Config Swagger

Add first swagger dependency:

<dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger2</artifactId>
      <version>2.9.2</version>
</dependency>

<dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger-ui</artifactId>
      <version>2.9.2</version>
</dependency>

Then create a class and add on top of the class below annotation:

@Configuration @EnableSwagger2

Now Add below Code:

@Bean
public Docket api() {
    return new Docket(DocumentationType.SWAGGER_2).select()
            .apis(RequestHandlerSelectors.basePackage("com.aamnapm.counting")) //your package name
            .paths(PathSelectors.any())
            .build().apiInfo(apiEndPointsInfo());
}

private ApiInfo apiEndPointsInfo() {
    return new ApiInfoBuilder().title("Spring Boot REST API")
            .description("Employee Management REST API")
            .license("Apache 2.0")
            .licenseUrl("http://www.apache.org/licenses/LICENSE-2.0.html")
            .version("1.0.0")
            .build();
}

On class controller add @Api(value = "your title") and On the Entity or DTO class add @ApiModel(value = "dto",description = "description")
