创建两个工程，一个是nacos-provider, 另一个是naocos-consumer；
添加nacos-provider的依赖

- provider基本代码
@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服务地址
nacos:
server-addr: 127.0.0.1:8848
在启动类上添加@EnableDiscoveryClient注解
- consumer基本代码
@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服务地址
nacos:
server-addr: 127.0.0.1:8848
在启动类添加@EnableFeignClients，@EnableDiscoveryClient注解
调用结果：
