spring云zuul：如何返回服务httpstatus（或处理zuul状态返回）？

Question

如果尤里卡服务ID使用zuul路线，服务还有些则httpStatus像503

curl 10.1.0.21:5701/usr/users/xxx/a -H "Api-Version: v10" -i 

返回：

HTTP/1.1 503 Service Unavailable 
Set-Cookie: Session-Token=9e66fb56-21e2-457a-a00f-f788c5ce820b; path=/; domain=.0.21:5701; HttpOnly; Max-Age=2592000; Expires=Sat, 29-Oct-2016 09:23:41 GMT

对我的作品与最新的弹簧云的Netflix（1.2.0）：

@SpringBootApplication 
@EnableZuulProxy 
public class SimpleApplication { 

    public static void main(String[] args) { 
     SpringApplication.run(SimpleApplication.class, args); 
    } 
} 

与application.properties：

zuul.routes.test.url=http://httpstat.us/503 
zuul.routes.test.path=/test/** 

和：

$ curl localhost:8080/test/ 
> GET /test/ HTTP/1.1 
> User-Agent: curl/7.35.0 
> Host: localhost:8080 
> Accept: */*
