springcloud-feign 断路由

微信：zmjyyg (一对一讲解)

原理：当service-A 中的接口获取service-B中的请求时，如果service-B响应timeout, 此时请求会进入service-A 中设置的断路由中。

------------------------------------------------------------------------------------------------------------------------

service-A中：

@FeignClient(name = "eureka-client-first", fallback = DemoRemoteHystrix.class)
public interface FeignInterfaceClient {

　　@RequestMapping(value = "/feigns/postRequestByParam", method = RequestMethod.POST)
　　String postRequestByParam(@RequestBody(required = false) User user);

}

 

service-A中需要一个FeignClient 接口的实现中，在实现方法中写逻辑代码

@Component
public class DemoRemoteHystrix implements FeignInterfaceClient {

　　@Override
　　public String postRequestByParam(User user) {
　　System.out.println("---------yes!!!-------断路由成功");
　　return null;
}
