Spring Cloud Feign demo

Spring Cloud Feign 测试demo

测试使用的是之前测试Spring Cloud Eureka服务注册的demo项目。参考Spring Cloud Eureka demo

测试目标：consumer访问provider提供的服务使用spring cloud feign访问。

1. maven配置

    org.springframework.cloud
    spring-cloud-starter-openfeign

2.开启Feign功能

使用@EnableFeignClients注解

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

3.封装Feign客户端

/**
 * @author wangerniu
 * @date 2020/9/30 14:17
 */
@FeignClient(name = "server-provider")
public interface FeignDemoClient {
    
    @RequestMapping(value = "/user/test", method = RequestMethod.GET)
    String getIdentity();
    
}

4.测试用例

/**
 * @author wangerniu
 * @date 2020/9/29 14:57
 */
@RestController
@Slf4j
public class TestController {

    private final FeignDemoClient feignDemoClient;

    public TestController(FeignDemoClient feignDemoClient) {
        this.feignDemoClient = feignDemoClient;
    }

    @GetMapping("/test")
    public String getUserIdentity() {
        return feignDemoClient.getIdentity();
    }

}

5.测试

启动所有服务，访问http://127.0.0.1:8091/test ，成功返回结果，测试成功
