Discovery route locator not picking up new services

Hello, I used springboot2.2.2.RELEASE,springcloud Hoxton.SR1.

• When I started order is

eurekaServer(design-eureka)-->configServer(design-config)-->gateway(design-gateway)-->authServer(design-auth).
The request url is
http://localhost:9000/DESIGN-AUTH/auth/login

  @RequestMapping(value = "/login",method = RequestMethod.POST)
    public String login() {
        String result="{\"code\":200,\"data\":\"success\"}";
        return result;
    }

The result is 404 error.can‘t reach authServer

• When I started order is

eurekaServer(design-eureka)-->configServer(design-config)-->authServer(design-auth)-->gateway(design-gateway)

The result is ok，The authServer is ok.
