How to call java controller class from angularjs

I have a web project..no service call but there is a Java controller where one of the methods returns a string .. this needs to be read in my js file .. I cannot get the data or remove the url mapped to the controller class.

Controller class:

@Controller
@RequestMapping("/user")
public class UserController {    

    @GET        
    @RequestMapping(method = RequestMethod.GET, value = "/details")
    public @ResponseBody String getUserDetails(HttpServletRequest request) {
        System.out.println("1");
        UserInfoDTO userInfoDTO = new UserInfoDTO();

        userInfoDTO.setUserName("Akriti");
        userInfoDTO.setUserId("1111");
        String userString = new Gson().toJson(userInfoDTO);
        //return new ModelAndView("index.jsp", "userString", userString);
        System.out.println("user" + userString);
        return userString;
    }

      

        
        
        
      

    

And the js file I'm using:

'use strict';
(function () {
    /**
     * @ngdoc overview
     * @name User Module
     * @description Logged in User
     */
    var user = angular.module('sol.user', []);
    user.controller('sol.user.UserController', UserController);
    alert("Hi");
   // $state.go('home.user');
   function UserController($scope, $http){
       alert("Hello");
       $http({method: 'GET',
            url: '/user/details'})
            .success(function(data) {
                $scope.profiles = data;
            })
            .error(function(data) {
                  $scope.profiles = data;
                alert( "failure");
                alert( data);
            });
       $state.go('home.user');
   }
})();

      

        
        
        
      

    

The url doesn't run at all as none of the system instructions are printed to the console. Please, help
