• provider部分代碼

@RestController
public class ProviderController {

    @GetMapping("invoke")
    public String invoke() {
        return LocalTime.now() + " invoke;
    }
}

 

　　application.yml

server:
  port: 8070
spring:
  application:
    name: nacos-provider
  cloud:
    # nacos服務地址
    nacos:
      server-addr: 127.0.0.1:8848

　　

　　在啟動類上添加@EnableDiscoveryClient注解

 

• consumer部分代碼

@RestController
public class ConsummerController {

    @Autowired
    private ProviderFeign providerFeign;

    @GetMapping("/test")
    public String test() {
        return providerFeign.invoke();
    }
}

　　

@FeignClient("nacos-provider")
public interface ProviderFeign {

    @GetMapping("invoke")
    String invoke();
}

 

　　application.yml

server:
  port: 8071
spring:
  application:
    name: nacos-consumer
  cloud:
    # nacos服務地址
    nacos:
      server-addr: 127.0.0.1:8848

　　

　　在啟動類添加@EnableFeignClients，@EnableDiscoveryClient注解
