搭建Employ员工服务

创建数据库

1.执行microserivcecloud-database中的Employ.sql文件创建员工服务需要用到的表当然也可以自己考出来执行

use db;
SET STORAGE_ENGINE = InnoDB;

DROP TABLE IF EXISTS `employ`;
CREATE TABLE `employ` (
  `id` bigint(20) NOT NULL COMMENT '员工编号',
  `name` varchar(48) NOT NULL COMMENT '名字',
  `departmentId` bigint(10) NOT NULL COMMENT '部门编号',
  `datasourceId` varchar(64) NOT NULL COMMENT '数据存储位置',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
insert into employ(id,name,departmentId,datasourceId) values(1,"zhansan",1,DATABASE());
insert into employ(id,name,departmentId,datasourceId) values(2,"lisi",2,DATABASE());
insert into employ(id,name,departmentId,datasourceId) values(3,"wangwu",3,DATABASE());
insert into employ(id,name,departmentId,datasourceId) values(4,"maliu",4,DATABASE());

2.创建springboot+mybatis整合项目 2.1创建microservicecloud-api 子模块项目用于存放公共的接口和实体修改pom.xml文件

 <!--添加lombok依赖-->
 <dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
</dependency>

2.2利用MyBatisCodeHelper-Pro生成mybatis的mapper接口和数据库实体到microservicecloud-api中生成结果如下

com.styz.microservicecloud.entity.Employ #实体
com.styz.microservicecloud.mapper.EmployMapper #mapper接口
microservicecloud-api/src/main/resources/mapperxml/EmployMapper.xml #mapper.xml sql 文件

然后执行mvn install操作 2.3创建microservicecloud-employservice 模块修改pom文件

<dependencies>
    <dependency>
        <groupId>com.com.styz.microservicecloud</groupId>
        <artifactId>microservicecloud-api</artifactId>
        <version>${project.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>

    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
    </dependency>
    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis</artifactId>
        <version>3.5.1</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.3.0</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
</dependencies>

创建com.styz.microservicecloud包新建EmployServiceApplication启动类

@SpringBootApplication
@MapperScan("com.com.styz.microservicecloud.mapper")
public class EmployServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployServiceApplication.class);
    }
}

然后创建com.styz.com.styz.microserivcecloud.service.EmployService接口以及其实现类

public interface EmployService {
    /**
     * 获取所有员工
     * @return
     */
    public List<Employ> getAllEmployes();

    /**
     * 根据Id获取指定员工
     * @param id
     * @return
     */
    public Employ getEmployById(long id);
}

@Service
public class EmployServiceImpl implements EmployService {
    @Autowired
    private EmployMapper employMapper;

    public List<Employ> getAllEmployes() {
        return employMapper.listAll();
    }

    public Employ getEmployById(long id) {
        return employMapper.selectByPrimaryKey(id);
    }
}

然后创建com.styz.com.styz.microserivcecloud.controller.EmployController

@RestController
@RequestMapping("/employ")
public class EmployController {
    @Autowired
    private EmployService employService;

    @RequestMapping("/getAllEmployes")
    public List<Employ> getAllEmployes(){
        return employService.getAllEmployes();
    }
    @RequestMapping("/getEmployById/{id}")
    public Employ getEmployById(@PathVariable("id")long id){
        return employService.getEmployById(id);
    }
}

添加配置文件

#应用程序使用的端口
server:
  port: 8999
#mybatis相关配置
mybatis:
  config-location: classpath:mybatis/mybatis.cfg.xml
  type-alias-package: com.com.styz.microservicecloud.entity
  mapper-locations:
    - classpath*:mapperxml/*Mapper.xml
#数据源配置
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://k8s-n1:3307/db
    username: root
    password: 123456
    dbcp2:
      min-idle: 5
      initial-size: 5
      max-idle: 10
      max-total: 20
      max-wait-millis: 10
# 服务名称
  application:
    name: EmployService

mybatis/mybatis.cfg.xml

<?xml version="1.0" encoding="UTF-8" ?>
        <!DOCTYPE configuration
                PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
                "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <!--二级缓存开启-->
        <setting name="cacheEnabled" value="true"/>
    </settings>
</configuration>

**注意：@MapperScan("com.com.styz.microservicecloud.mapper")**必须扫描到API模块里的mapper接口

2.5 自嗨一下访问http://localhost:8999/employ/getAllEmployes 查看一下是否正常返回自此单机服务已经整合完毕

创建消费者服务microservicecloud-employconsummer

1.新建模块microservicecloud-employconsummer修改pom文件

<dependencies>
    <dependency>
        <groupId>com.com.styz.microservicecloud</groupId>
        <artifactId>microservicecloud-api</artifactId>
        <version>${project.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>
</dependencies>

2.添加配置application.yml

server:
  port: 8111
spring:
  application:
    name: EmployComsummer
  devtools:
    restart:
      enabled: true

3.新建config配置类com.styz.com.styz.com.styz.microservice.config.ConsummerConfigBean

@Configuration
public class ConsummerConfigBean {
   /**
    * RestTemplate 封装了httpclient的实现能够简化我们对请求的访问
    * @return 
    */
    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }
}

4.创建消费者controller com.styz.com.styz.com.styz.microservice.controller.EmployConsumerController

@RestController
@RequestMapping("/comsummer")
public class EmployConsumerController {
    //服务提供方的地址：http://localhost:8999/employ/getAllEmployes
    public static final String EMPLOY_PROVIDE_URL="http://localhost:8999/employ";
    @Autowired
    private RestTemplate restTemplate;

    @RequestMapping("/getById/{id}")
    public Employ getEmployById(@PathVariable("id") long id){
        return restTemplate.postForObject(EMPLOY_PROVIDE_URL+"/getEmployById/"+id,null,Employ.class);
    }
    @RequestMapping("/getAllEmployes")
    public List<Employ> getAllEmployes(){
        return restTemplate.postForObject(EMPLOY_PROVIDE_URL+"/getAllEmployes",null,List.class);
    }
}

5.新建消费者启动类：com.styz.com.styz.com.styz.microservice.EmployComsumerApplication

@SpringBootApplication
public class EmployComsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployComsumerApplication.class);
    }
}

至此单体消费者实例已经完成。自嗨一下：访问http://localhost:8111/consummer/getById/1 看看能不能调用到服务端提供的服务

Eureka注册中心搭建

Eureka主要的功能就是服务注册与发现。是Netflix公司下开源一款产品，功能比较单一基于AP原则实现。cs架构模式实现,想要详细了Eureka可以百度。

单机模式

创建microservicecloud-registry-8211 模块

1.修改pom文件

 <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <finalName>${project.name}</finalName>
                </configuration>
            </plugin>
        </plugins>
    </build>

2.创建com.styz.com.styz.com.styz.microservice.RegistryApplication_8211 启动类

@SpringBootApplication
@EnableEurekaServer
public class RegistryApplication_8211 {
    public static void main(String[] args) {
        SpringApplication.run(RegistryApplication_8211.class,args);
    }
}

3.配置文件

spring:
  application:
    name: registry-8211

eureka:
  instance:
    #euraka 服务器实例名称
    #主机名字需要修改host文件
    hostname: registry8211
  client:
    #false表示不向注册中心注册自己
    register-with-eureka: false
    #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    fetch-registry: false
    service-url:
      #单机配置 http://${eureka.instance.hostname}:${server.port}/eureka
      #集群环境搭建:http://registry8212:8212/eureka/,http://registry8213:8213/eureka/
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka
server:
  port: 8211

单机注册中心已经完成访问 http://registry8211:8211/ 就会出现注册中心的界面

集群搭建

修改microservicecloud-registry-8211 模块

1.只需要修改bootstrap.yml中的

 defaultZone: http://registry8212:8212/eureka/,http://registry8213:8213/eureka/

拷贝microservicecloud-registry-8211 两份

microservicecloud-registry-8212 microservicecloud-registry-8213 同理修改

 
spring:
  application:
    name: registry-8212

eureka:
  instance:
    #euraka 服务器实例名称
    hostname: registry8212
  client:
    #false表示不向注册中心注册自己
    register-with-eureka: false
    #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    fetch-registry: false
    service-url:
      #单机配置 http://${eureka.instance.hostname}:${server.port}/eureka
      #集群环境搭建
      defaultZone: http://registry8211:8211/eureka/,http://registry8213:8213/eureka/
server:
  port: 8212

spring:
  application:
    name: registry-8213

eureka:
  instance:
    #euraka 服务器实例名称
    hostname: registry8213
  client:
    #false表示不向注册中心注册自己
    register-with-eureka: false
    #false表示自己端就是注册中心，我的职责就是维护服务实例，并不需要去检索服务
    fetch-registry: false
    service-url:
      #单机配置 http://${eureka.instance.hostname}:${server.port}/eureka
      #集群环境搭建
      defaultZone: http://registry8211:8211/eureka/,http://registry8212:8212/eureka/
server:
  port: 8213

修改hosts文件

127.0.0.1  registry8213 registry8212 registry8211

至此集群模式搭建完毕，可以分别访问 http://registry8211:8211/ http://registry8212:8212/ http://registry8213:8213/ 出现Eureka的界面表示成功。

注册服务到注册中心

新建microservicecloud-employproviderwithregistry

拷贝microserivicecloud-employservice中的代码和配置文件到microservicecloud-employproviderwithregistry 模块中修改pom文件

<!--添加注册中心依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<!--添加springboot监控依赖-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

添加bootstrap.yml文件

#服务名称
spring:
  application:
    name: EmployService
eureka:
  client:
    service-url:
      #单机配置：http://localhost:8211/eureka
      defaultZone: http://registry8212:8212/eureka/,http://registry8213:8213/eureka/,http://registry8211:8211/eureka/
  # 修改注册服务的名字
  instance:
    instance-id: EmployService-8999
    # 防问路径可以显示IP地址
    prefer-ip-address: true
# 添加服务Info信息
info:
  app.name: EmployService-8999
  app.describution: 员工服务
  company.name: com.com.styz
  author.name: liuy
  build.artifactId: $project.artifactId$
  build.version: $project.version$

修改启动类com.styz.com.styz.microserivcecloud.EmployServiceApplication 添加@EnableEurekaClient注解

@SpringBootApplication
@MapperScan("com.com.styz.microservicecloud.mapper")
@EnableEurekaClient
public class EmployServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployServiceApplication.class,args);
    }
}

然后可以查看注册中心是否有服务注册进去了。

消费者调用

修改microservicecloud-employconsummer中的com.styz.com.styz.com.styz.microservice.controller.EmployConsumerController 中的

// EMPLOYSERVICE为服务名称
public static final String EMPLOY_PROVIDE_URL="http://EMPLOYSERVICE/employ";

修改pom添加eureka客户端依赖

 <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

修改启动类添加服务发现注解@EnableDiscoveryClient

@SpringBootApplication
@EnableDiscoveryClient
public class EmployComsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployComsumerApplication.class,args);
    }
}

修改yml文件

eureka:
  client:
    service-url:
      #单机配置：http://localhost:8211/eureka
      defaultZone: http://registry8212:8212/eureka/,http://registry8213:8213/eureka/,http://registry8211:8211/eureka/
    register-with-eureka: false

此时访问消费者就能够完成消费者调用服务端服务的调用了

服务集群搭建

为了介绍下面的resttemplate+ribbon 和feign负载均衡，需要将服务作集群搭建。基本架构是，每个服务访问自己独立的数据库，数据上构造一定的差异，这样方便我们测试负载均衡。

执行Employ-cluster.sql文件中的sql

创建三个不同的库，同样的表。然后插入不同的数据。

拷贝microservicecloud-employproviderwithregistry 三份

分别为microservicecloud-employ-provider-8911 microservicecloud-employ-provider-8912 microservicecloud-employ-provider-8913 具体修改内容见代码。

创建microservicecloud-employ-comsumer-robbin 模块

1.修改pom文件

<!-- 添加 ribbon依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

修改启动类

@SpringBootApplication
@EnableDiscoveryClient
//指定某个服务用某种负载均衡算法
@RibbonClient(name = "EMPLOYSERVICE",configuration = MyRules.class)
public class EmployComsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployComsumerApplication.class,args);
    }
}

com.styz.rules.MyRules

@Configuration
public class MyRules {
    @Bean
    @Primary
    public IRule getRobbinRule(){
        return new RandomRule();
    }
}

新建自定义负载均衡算法 com.styz.com.styz.com.styz.microservice.robbin.CountRobbinRule

public class CountRobbinRule implements IRule {
    private ILoadBalancer loadBalancer;
    private AtomicInteger count = new AtomicInteger(0);
    private AtomicInteger serverIndex = new AtomicInteger(0);
    @Override
    public Server choose(Object o) {
        List<Server> allServers = loadBalancer.getAllServers();
        while (true){
            if(count.get() > 5){
                if(serverIndex.incrementAndGet() > allServers.size()){
                    serverIndex.set(serverIndex.get()%allServers.size());
                }
                count.set(0);
            }else {
                count.incrementAndGet();
                return allServers.get(serverIndex.get());
            }
        }
    }

    @Override
    public void setLoadBalancer(ILoadBalancer iLoadBalancer) {
        loadBalancer = iLoadBalancer;
    }

    @Override
    public ILoadBalancer getLoadBalancer() {
        return loadBalancer;
    }
}

修改配置文件类com.styz.com.styz.com.styz.microservice.config.ConsummerConfigBean

@Configuration
public class ConsummerConfigBean {
    /**
     * @LoadBalanced 注解会使用robbin负载均横算法。默认是轮训，如需修改得显示声明对应的算法。
     * 如果没有声明，默认就是轮训
     * robbin 提供7种轮训算法，我们可以手动扩展实现负载均衡算法。
     */
    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplate(){
        RestTemplate restTemplate = new RestTemplate();
        return restTemplate;
    }
}

启动注册中心，启动服务提供者集群，启动消费者，访问http://localhost:7111/consummer/getById/1 查看负载均衡情况。

引入Feign负载均衡

RestTemplate+robbin是基于微服务名称封装httpclient的方式完成的服务调用。

而Feign是在此基础上又进行了一次封装，使得消费端可以通过注解+接口的方式用接口的方式完成服务的调用，有点类似于Dubbo中接口调用一样。只是底层实现不一样， Dubbo是RPC，而Feign是http的Restful调用。

创建microservicecloud-employ-consummer-feign模块

修改pom文件添加Feign支持

            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
    </dependencies>

2.修改microservicecloud-api 添加Feign接口com.styz.microservicecloud.service.EmployClientService

@FeignClient(value = "EMPLOYSERVICE")
public interface EmployClientService {
    //注意此时的url是服务端的全路径，不是客户端哦
    @RequestMapping(value = "/employ/getAllEmployes",method = RequestMethod.POST)
    public List<Employ> getAllEmployes();

    @RequestMapping(value = "/employ/getEmployById/{id}",method = RequestMethod.POST)
    public Employ getEmployById(@PathVariable("id")long id);

}

修改com.styz.com.styz.com.styz.microservice.controller.EmployConsumerController

@RestController
@RequestMapping("/comsummer")
public class EmployConsumerController {
    //EmployClientService 为Feign接口
    @Autowired
    private EmployClientService clientService;

    @RequestMapping("/getById/{id}")
    public Employ getEmployById(@PathVariable("id") long id){
       return clientService.getEmployById(id);
    }
    @RequestMapping("/getAllEmployes")
    public List<Employ> getAllEmployes(){
        return clientService.getAllEmployes();
    }
}

修改启动类com.styz.com.styz.com.styz.microservice.EmployComsumerApplication

@SpringBootApplication
@EnableDiscoveryClient
//注意EnableFeignClients 一定要扫描到@FeignClient的包否则会报错
@EnableFeignClients(basePackages = "com.styz.microservicecloud.service")
public class EmployComsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployComsumerApplication.class,args);
    }
}

此时再次访问http://localhost:7111/consummer/getById/1 查看负载均衡情况

添加熔断Hystrix支持

Hystrix是什么？请自行百度。

新建microservicecloud-employ-consummer-hystrix 模块

修改pom文件

            <artifactId>lombok</artifactId>
        </dependency>
    </dependencies>

修改启动类添加

@SpringBootApplication
@EnableDiscoveryClient
//注意EnableFeignClients 一定要扫描到@FeignClient的包否则会报错
@EnableFeignClients(basePackages = "com.styz.microservicecloud.service")
//添加熔断机制
@EnableHystrix
@ComponentScan("com.styz")
public class EmployComsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployComsumerApplication.class,args);
    }
}

修改controller 添加@HystrixCommand，一般情况下熔断一般实现在服务提供端，我这里只是demo就实现在消费端了。 @HystrixCommand能捕获异常可以根据异常不同，进行不同的熔断操作。

@RestController
@RequestMapping("/comsummer")
public class EmployConsumerController {
    @Autowired
    private EmployClientService clientService;

    @RequestMapping("/getById/{id}")
    @HystrixCommand(fallbackMethod = "processEmployException")
    public Employ getEmployById(@PathVariable("id") long id){
        Employ employ = clientService.getEmployById(id);
        if(null == employ){
            throw new RuntimeException("未找到对应ID的员工！");
        }
        return employ;
    }

    /**
     * 这个方法可以写在服务端，也可以写在消费端，如果异常导致的最好写在服务端，如果非异常，可以实现在消费端
     * 方法写在服务端叫熔断，写在消费端叫降级。
     * HystrixCommand 注解能实现的熔断，但是缺点非常明显，容易导致方法膨胀：也就是每个方法都需要写一个异常方法
     * 方法会非常多，不便与维护。
     *
     * @param id
     * @return
     */
    public Employ processEmployException(@PathVariable("id") long id){
        Employ employ = new Employ();
        employ.setId(id);
        employ.setName("未找到对应ID的员工!");
        return employ;
    }
    @RequestMapping("/getAllEmployes")
    public List<Employ> getAllEmployes(){
        return clientService.getAllEmployes();
    }
}

@HystrixCommand 业务代码耦合严重，方法容易膨胀，所以有了Fegin熔断机制可以在接口上面实现熔断，从而解藕修改com.styz.microservicecloud.service.EmployClientService

/**
 * 服务降级处理：
 * 1.添加fallbackFactory 或者Fallback类
 * 2.开启服务降级：
 * feign:
 *   hystrix:
 *     enabled: true
 * 注意fallbackFactory类或者Fallback类要能被扫描到。否则不会生效。
 */

@FeignClient(value = "EMPLOYSERVICE",fallbackFactory = EmployClientServiceFallbackFactory.class)
public interface EmployClientService {
    //注意此时的url是服务端的全路径，不是客户端哦
    @RequestMapping(value = "/employ/getAllEmployes",method = RequestMethod.POST)
    public List<Employ> getAllEmployes();

    @RequestMapping(value = "/employ/getEmployById/{id}",method = RequestMethod.POST)
    public Employ getEmployById(@PathVariable("id")long id);

}

@Component
public class EmployClientServiceFallbackFactory implements InitializingBean,FallbackFactory<EmployClientService> {

    @Override
    public void afterPropertiesSet() throws Exception {

    }

    public static class EmployClientServiceFallback implements EmployClientService{

        @Override
        public List<Employ> getAllEmployes() {
            ArrayList<Employ> employs = new ArrayList<>();
            employs.add(new Employ().setName("********暂停服务*****"));
            System.out.println("*************暂停服务****************");
            return employs;
        }

        @Override
        public Employ getEmployById(long id) {
            return new Employ(id,"该ID不存在",0L,"");
        }
    }

    @Override
    public EmployClientService create(Throwable throwable) {
        return new EmployClientServiceFallback();
    }
}

开启Fegin降级机制

feign:
  hystrix:
    enabled: true

此时称之为Feign+fallback 服务降级何谓服务降级：简单的说就是当整个系统资源不够用时，为了满足某些服务依然可用，就需要忍痛将其他服务停掉，将系统资源释放用以支持其他服务。此时停掉的服务不能影响整个系统的使用，就需要在消费端在访问不到服务的情况下，将服务进行降级处理。

启动消费者测试一下服务的熔断和降级看看。

hystrix.stream

springboot2.0中hystrix.stream url出现404错误问题解决办法1 添加配置类com.styz.com.styz.com.styz.microservice.config.HystrixConfig

@Configuration
public class HystrixConfig {
    @Bean
    public HystrixMetricsStreamServlet hystrixMetricsStreamServlet(){
        return new HystrixMetricsStreamServlet();
    }

    @Bean

        ServletRegistrationBean registrationBean = new ServletRegistrationBean();
        registrationBean.setServlet(servlet);
        //是否启用该registrationBean
        registrationBean.setEnabled(true);
        registrationBean.addUrlMappings("/hystrix.stream");
        return registrationBean;
    }
}

修改yml文件

    web:
      exposure:
        include:

访问 http://localhost:7112/hystrix 页面，出现豪猪图片表示成功访问 http://localhost:7112/hystrix/hystrix.stream 出现ping 字眼表示成功 http://localhost:7112/hystrix 这个页面如何使用，请自行百度吧。

前面使用的/hystrix.stream端点监控单个微服务。然而在使用微服务架构的应用系统一般会包含多个微服务，每个微服务通常都会部署多个实例。如果每次只能查看单个实例的监控数据，就必须在Hystrix Dashboard上切换想要监控的地址，这显然很不方便。

Turbine简介

Turbine是一个聚合Hystrix监控数据的工具，它可将所有相关/hystrix.stream端点的数据聚合到一个组合的/turbine.stream中，从而让集群的监控更加方便

使用Turbine监控多个微服务

创建microservicecloud-employ-consummer-hystrixDashborad-turbine 修改pom文件

<!--添加Turbine依赖-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-netflix-turbine</artifactId>
</dependency>

修改启动类添加@EnableTurbine注解

@SpringBootApplication
@EnableDiscoveryClient
//注意EnableFeignClients 一定要扫描到@FeignClient的包否则会报错
@EnableFeignClients(basePackages = "com.styz.microservicecloud.service")
//添加熔断机制
@EnableHystrix
@ComponentScan("com.styz")
//添加服务监控 1.服务端要添加对应的包spring-boot-starter-actuator
@EnableHystrixDashboard
@EnableTurbine
public class EmployConsummerTurbineApplication {
    public static void main(String[] args) {
        SpringApplication.run(EmployConsummerTurbineApplication.class,args);
    }
}

添加turbine配置

turbine:
  # app-config表示待监测的服务名称
  app-config: EmployComsummer-HystrixDashboard,EmployComsummer-HystrixDashboard-Turbine
  aggregator:
    cluster-config: default
  cluster-name-expression: new String("default")

turbine.appConfig ：配置Eureka中的serviceId列表，表明监控哪些服务 turbine.aggregator.clusterConfig ：指定聚合哪些集群，多个使用","分割，默认为default。可使用http://.../turbine.stream?cluster={clusterConfig之一}访问 turbine.clusterNameExpression ：

clusterNameExpression指定集群名称，默认表达式appName；此时：turbine.aggregator.clusterConfig需要配置想要监控的应用名称；
当clusterNameExpression: default时，turbine.aggregator.clusterConfig可以不写，因为默认就是default；
当clusterNameExpression: metadata['cluster']时，假设想要监控的应用配置了eureka.instance.metadata-map.cluster: ABC，则需要配置，同时turbine.aggregator.clusterConfig: ABC

测试

启动microservicecloud-employ-consummer-hystrixDashboard 和microservicecloud-employ-consummer-hystrixDashborad-turbine 访问http://localhost:7113/hystrix，监控http://localhost:7113/turbine.stream 后然后分别访问 http://localhost:7112/comsummer/getById/1 和http://localhost:7113/comsummer/getById/1 查看监控面板的变化。

添加网关Zuul支持

启动类添加

@SpringBootApplication

@EnableDiscoveryClient
public class GatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(GatewayApplication.class,args);
    }
}

添加配置服务Config支持

新建microservicecloud-config模块

修改pom文件

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

创建com.styz.microservicecloud.ConfigServerApplication

@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ConfigServerApplication.class,args);
    }
}

修改配置文件

spring:
  cloud:
    config:
      server:
        native:
          search-locations: classpath:/config
#  本地模式
  profiles:
    active: native

server:
  port: 8888

此配置意思是config配置服务器扫描服务所在的config目录。将config目录下的配置文件发不成restful接口。

启动com.styz.microservicecloud.ConfigServerApplication 然后访问http://localhost:8888/config/dev 就能访问到application-dev.yml配置。访问http://localhost:8888/employservice/default 就能访问到employsevice配置。

修改服务提供者

修改microservicecloud-employ-provider-8911 让其加载config服务器上的配置 1.删除原来的application.yml 2.添加依赖spring-cloud-starter-config 其实原来就有。

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
</dependency>

3.修改bootstrap.yml 添加如下内容

spring:
  application:
    name: EmployService
  cloud:
    config:
      uri: http://config:8888
      fail-fast: true

spring.cloud.config.url 配置的就是配置服务的地址。

重启服务端microservicecloud-employ-provider-8911 测试一下是否正常

采用spring.cloud.config.url 这种方式指定url的方式直接连接，有明显缺陷，当配置服务器挂掉，无法加载远程配置。就有了将config服务器服务化，注册到 Eureka，利用服务发现的方式去找服务的地址，从而实现config地址动态变化，尽管 config服务器发生变化，服务端也无需在修改对应的url。同时config配置服务器可以做集群注册到Eureka，从而也可避免单点故障。

配置中心config把配置放置到git仓库

之前配置放在本地了，现在将配置迁移到git仓库，好处是config服务做集群的时候可以统一从仓库拉取配置，自己不需要维护配置文件。

创建存放配置的git目录

在microservicecloud文件夹下创建microservicecloud-config-dir目录将配置文件放入此文件，提交github。

新建microservicecloud-config-git 模块

1.修改pom文件

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-actuator</artifactId>
        </dependency>
    </dependencies>

2.新建类com.styz.microservicecloud.GItConfigServerApplication

@EnableConfigServer
public class GItConfigServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(GItConfigServerApplication.class,args);
    }
}

3.修改yml

spring:
  application:
    name: GitConfigServer
  cloud:
    config:
      # label 表示是哪个分支
      label: master
      server:
        git:
          # git用户密码私有仓库必填
          username:
          password:
          # uri 是git的地址
          uri: https://github.com/liuyong520/microservicecloud
          # search-paths 搜索git仓库哪个目录，相对地址
          search-paths: microservicecloud-config-dir

eureka:
  client:
    register-with-eureka: true
    service-url:
      defaultZone: http://registry8212:8212/eureka/,http://registry8213:8213/eureka/,http://registry8211:8211/eureka/
  instance:
    instance-id: GitConfigServer
    prefer-ip-address: true

server:
  port: 8888

server端就此改造完了

测试一下访问http://localhost:8888/config/dev 就能访问到application-dev.yml配置。访问http://localhost:8888/employservice/default 就能访问到employsevice配置。

修改microservicecloud-employ-provider-8911

采用服务发现的方式连接configsever。

spring:
  application:
    name: EmployService
  cloud:
    config:
      name: EmployService  #指定配置文件名称
      profile: default
      label: master
      discovery:
        enabled: true
        service-id: GitConfigServer #configserver服务

重启服务端看看是否正常启动。

添加链路跟踪

何谓链路跟踪? 在分布式系统中往往一次简单的请求，往往涉及到一系列的服务调用，服务A调用服务B，服务B调用服务C。这样的服务链上如果某个服务发生故障，无法快速定外到故障点，从而无法快速定位问题。而链路跟踪是就是跟踪整个服务之间的调用链，监控每个服务间的调用情况，以备在调用出现问题时，能快速定位问题。

zipKin 简介

Zipkin是一种分布式跟踪系统。它有助于收集解决服务体系结构中的延迟问题所需的计时数据。功能包括收集和查找此数据。

如果日志文件中有跟踪ID，则可以直接跳转到该文件。否则，您可以根据服务，操作名称，标签和持续时间等属性进行查询。将为您总结一些有趣的数据，例如在服务中花费的时间百分比，以及操作是否失败 Zipkin UI还提供了一个依赖关系图，显示了每个应用程序通过的跟踪请求数。这有助于识别聚合行为，包括错误路径或对已弃用服务的调用。

zipKin环境搭建

1.docker环境下：

docker run --name zipkin -d -p 9411:9411 openzipkin/zipkin

2.物理机

curl -sSL https://zipkin.io/quickstart.sh | bash -s
java -jar zipkin.jar

访问http://localhost:9411/ 出现zipkin UI界面为了演示一下链路跟踪需要搭建一个调用链环境，我这里用一个消费端和服务端来演示

修改服务提供者

1.新建microservicecloud-employ-provider-8911-sleuth 改造一下microservicecloud-employ-provider-8911 修改pom

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>

修改yml文件

spring:
  application:
    name: EmployService
  #添加链路跟踪
  sleuth:
    web:
      client:
        enabled: true
    sampler:
      probability: 1.0
  zipkin:
    base-url: http://k8s-n3:9411/

至此服务端改造完成

修改消费者

1.新建microservicecloud-employ-consummer-hystrix-sleuth模块改造一下microservicecloud-employ-consummer-hystrix 修改pom文件

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>

然后修改一下yml文件

server:
  port: 7115
spring:
  application:
    name: EmployComsummer-Hystrix
  devtools:
    restart:
      enabled: true
  sleuth:
    web:
      client:
        enabled: true
    sampler:
      probability: 1.0 #采样比例 1表示100%全部采样
  zipkin:
    base-url: http://k8s-n3:9411/

消费端完成启动服务端和消费端，访问http://localhost:7115/consummer/getById/1 调用一下消费者，然后去http://localhost:9411/zipkin/ 查看一下链路跟踪情况。

简单说一下链路跟踪的原理：针对给个服务的调用，都进行来埋点，消息的发送时刻以及消息的接收，都会被记录，以及包括服务名称，方法名称都被埋点探针记录下来，每次调用链上有唯一的tracId，这个是全局唯一的，然后用spanId区分是调用链上的哪个服务的哪个方法。以上数据的采集是通过httpReport方式提交的这种方式优点是简单直接，缺点是 1.网络问题：导致数据采集丢失 2。给zipkin带上访问上的压力量大可以压蹦zipkin 所以要改造一下：用消息队列进行解藕。就有了下面的sleuth+zipkin+rabbitmq方式，当然消息队列可以换成kafka也没有问题。

链路跟踪之sleuth+zipKin+rabbitmq

rabbitMq环境搭建

我这里用的是docker环境，所以直接贴出来docker下搭建过程。拉取官方镜像，镜像地址：https://hub.docker.com/_/rabbitmq/ 拉取镜像：docker pull rabbitmq，如需要管理界面：docker pull rabbitmq:management 执行指令启动RabbitMQ 无管理界面：

docker run --localhost rabbit-host --name my_rabbit -d -p 5672:5672 rabbitmq

有管理界面：

docker run --localhost rabbit-host --name my_rabbit -d -p 5672:5672 -p 15672:15672 rabbitmq:management

账号：guest 密码：guest

调整之前的消费者和服务者

修改pom文件

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>

修改yml文件

spring
    sleuth:
        web:
          client:
            enabled: true
        sampler:
          probability: 1.0
      zipkin:
        sender:
          type: rabbit
      rabbitmq:
        password: guest
        username: guest
        host: k8s-n3
        port: 5672
        virtual-host: /

修改zipkin服务端

docker run -d -p9411:9411 -e "RABBIT_ADDRESSES=rabbithost:5672" openzipkin/zipkin

如果你的rabbitMq用户名密码不是guest需要指定环境变量。
