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:-

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
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 "/".
