Spring Boot + Cloud | Zuul Proxy | 404 Error

Question

I am using Spring Cloud and Zuul proxy as gateway to my RESTful service.

Gateway Application (Spring Boot web app running on port 8080) relevant code:-

Main class:-

@SpringBootApplication
@EnableZuulProxy
public class WebfrontApplication extends WebMvcConfigurerAdapter {

    /**
     * @param args
     */
    public static void main(String[] args) {
        SpringApplication.run(WebfrontApplication.class, args);
    }
}

Zuul Mappings:-

zuul:
  routes:
    customer:
      path: /customer/**
      url: http://localhost:9000/

During startup of above UI Gateway application, I can see in my logs that mappings for proxies are registered:-

o.s.c.n.zuul.web.ZuulHandlerMapping      : Mapped URL path [/customer/**] onto handler of type [class org.springframework.cloud.netflix.zuul.web.ZuulController]

The REST service (A Spring Boot web app running on port 9000) relevant code:-

@RestController
@RequestMapping(value = "/customer")
public class CustomerController {

    @Autowired
    private CustomerService customerService;

    /**
     * Get List of All customers.
     * 
     * @return
     */
    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public List<Customer> list(Principal principal) {
        return customerService.list();
    }
}

Using a rest client (POSTMAN in my case) I am able to get response from above endpoint successfully (after taking care of auth token).

I am using AngularJS for in UI application to get data from the REST endpoint.

Relevant code:-

angular.module('customerModule').factory('customerService',function($http) {

    return {
        customerList : function(){
            // PROBLEM !!!!!
            // THIS CALL GIVES A 404 ERROR
            return $http.get('/customer/list');
        }
    };
});

The above call is giving back a 404 error:- This is what my Chrome debugger shows:-

Remote Address:127.0.0.1:8080
Request URL:http://localhost:8080/customer/list
Request Method:GET

What's is wrong here ? Are mappings incorrect or am I missing something else?

SOLVED

As per the accepted answer, changing the Zuul mapping worked when changed to:-

zuul:
 routes:
  resource:
   path: /customer/**
   url: http://localhost:9000/
   stripPrefix: false

I am following Dave Syer's blog from here: http://spring.io/blog/2015/01/12/spring-and-angular-js-a-secure-single-page-application — Kumar Sambhav, Mar 20 '15 at 04:32

There is no mapping for "/list" on the resource server (so it's a 404). You either need to set stripPrefix=false on your route declaration, or change the request mapping on the backend to "/".

I'm having a similar problem. Only in my case, it gives me a 405(Not Allowed) when `POST`ing, but `GET` works fine. Could you help with this? – cst1992 Apr 14 '16 at 11:07

You can also try the following configuration if you do not wish to set the stripPrefix property:

zuul:
  routes:
    customer:
      path: /customer/**
      url: http://localhost:9000/customer
