spring cloud zuul: How can return service httpstatus(or handle zuul status return)?

Question

If use zuul routes for eureka service id,service return some httpStatus like 503

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

Returns:

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

Session-Token-Expires: 2592000
Connection: keep-alive
ETag:

X-Application-Context: user-api-provider:5701

[{"key":"serviceUnavailable","message":"无效的接口"}]

But zuul reuturns ok/200, why? How can I change how Zuul handles statuses?

curl  10.1.0.19:8090/usr/users/xxx/a -H "Api-Version: v10" -i

Returns:

HTTP/1.1 200 OK
Connection: keep-alive
Content-Length: 0
X-Application-Context: zuul-server:8090

Answer 1

Works for me with latest spring-cloud-netflix (1.2.0):

@SpringBootApplication
@EnableZuulProxy
public class SimpleApplication {

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

with application.properties:

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

and:

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