1.依赖


  <!--引入open feign依赖-->
  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
  </dependency>
</dependencies>

2.启动注解


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

3.接口


@FeignClient("productservices")
public interface ProductClient {
  @RequestMapping("/product/findAll")
  public Map findAll();
}

4.服务调用


@Autowired
private ProductClient productClient;
@RequestMapping("/user/showProductMsg")
public Map showProductMsg() {
  Map msg = productClient.findAll();
  return msg;
}

5.超时设置
