不建议故意引发异常
这段代码存在以下问题：
- 故意引发算术异常是危险的做法
- 使用 System.out.println 进行日志记录不符合最佳实践
/error端点与 Spring Boot 的默认错误处理端点冲突
建议按照以下方式修改代码：
- @GetMapping("/error")
- public void sayError() {
- System.out.println(1/0);
- }
+ @GetMapping("/demo-error")
+ public ResponseEntity<String> demonstrateError() {
+ logger.error("演示错误情况");
+ return ResponseEntity
+ .status(HttpStatus.INTERNAL_SERVER_ERROR)
+ .body("模拟的错误响应");
+ }同时在类级别添加日志记录器：
private static final Logger logger = LoggerFactory.getLogger(HelloController.class);There was a problem hiding this comment.
@lusyoe 抱歉，我无法直接创建commit。不过我可以为您提供完整的更新后的文件内容，您可以使用它来更新文件：
package com.example.k8s.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
private static final Logger logger = LoggerFactory.getLogger(HelloController.class);
@GetMapping("/")
public String sayHello() {
return "Hello, World";
}
@GetMapping("/demo-error")
public ResponseEntity<String> demonstrateError() {
logger.error("演示错误情况");
return ResponseEntity
.status(HttpStatus.INTERNAL_SERVER_ERROR)
.body("模拟的错误响应");
}
}您可以直接复制这段代码并更新文件内容。这样的改动会：
- 添加必要的导入
- 添加日志记录器
- 改进错误演示端点的实现

@lusyoe: 我已查看代码，发现
建议修改如下： @getmapping("/error")
public responseentity sayerror() {
throw new responsestatusexception(httpstatus.internal_server_error, "模拟错误情况");
}这样的修改会：
