Spring MVC not being called by the Angular JS controller
Question
I'm trying to intgrate Angular JS with an existing Spring MVC project. I had à problem calling a Spring controller from the Angular JS controller.
This is my app.js :
'use strict';
var AdminApp = angular.module('AdminApp',[]);
And the service:
'use strict';
AdminApp.factory('AdminService', ['$http', '$q', function($http, $q) {
return {
fetchAllTerminals: function() {
return $http.get('http://localhost:8081/crmCTI/admin/terminal')
.success(function(response) {
console.log('Service');
return response.data;
})
.error(function(errResponse) {
console.error('Error while fetching terminals');
return $q.reject(errResponse);
});
}
};
}]);
and the controller:
'use strict';
AdminApp.controller('AdminController', ['$scope', 'AdminService', function($scope, AdminService) {
var self = this;
self.terminal={id:'',connectedUser:'',type:'',state:''};
self.terminals=[];
self.fetchAllTerminals = function() {
console.log('Controller');
AdminService.fetchAllTerminals()
.success(function() {
self.terminals = d;
})
.error(function() {
console.error('Error while fetching Terminals');
});
};
self.reset = function() {
self.terminal = {id : null, connectedUser : '', type : '', state : ''};
};
}]);
The JSP I'm using to display the data is:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head></head>
<body ng-app="AdminApp" ng-init="names=['Jani','Hege','Kai']">
<div ng-controller="AdminController as adminController">
<table>
<thead>
<tr>
<th>Id</th>
<th>Login</th>
<th>Type</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="terminal in adminController.terminals">
<td>{{terminal.id}}</td>
<td>{{terminal.connectedUser}}</td>
<td>{{terminal.type}}</td>
</tr>
</tbody>
</table>
</div>
<script type="text/javascript" src="${pageContext.request.contextPath}/vendors/angular/1.4.4/angular.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/app.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/controller/admin-controller.js"></script>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/service/admin-service.js"></script>
</body>
</html>
I can access my Spring Controller from a web browser and it returns some data but it's not being called by the Angular JS controller
Am I missing something here? Could you please help me?
Thank you

try this:
'use strict';
angular.module('AdminApp',[]);
And the service:
'use strict';
angular.module('AdminApp').factory('AdminService', ['$http', '$q', function($http, $q) {
return {
fetchAllTerminals: function() {
return $http.get('http://localhost:8081/crmCTI/admin/terminal')
.success(function(response) {
console.log('Service');
return response.data;
})
.error(function(errResponse) {
console.error('Error while fetching terminals');
return $q.reject(errResponse);
});
}
};
}]);
controller:
'use strict';
angular.module('AdminApp').controller('AdminController', ['$scope', 'AdminService', function($scope, AdminService) {
var self = this;
self.terminal={id:'',connectedUser:'',type:'',state:''};
self.terminals=[];
self.fetchAllTerminals = function() {
console.log('Controller');
AdminService.fetchAllTerminals()
.success(function() {
self.terminals = d;
})
.error(function() {
console.error('Error while fetching Terminals');
});
};
self.reset = function() {
self.terminal = {id : null, connectedUser : '', type : '', state : ''};
};
}]);

To return a data from your service function you should use .then function which has ability to return a data when promise gets resolved OR reject. That you can't to with .success & .error function.
.success&.errormethod of$httphas been **deprecated
Factory
AdminApp.factory('AdminService', ['$http', '$q', function($http, $q) {
return {
fetchAllTerminals: function() {
return $http.get('http://localhost:8081/crmCTI/admin/terminal')
.then(function(response) {
console.log('Service');
return response.data;
},function(errResponse) {
console.error('Error while fetching terminals');
return $q.reject(errResponse);
});
}
};
}]);
Then controller method will again place .then function on the factory method. So the 1st function of .then will get called on resolved of fetchAllTerminals call, if it gets rejected 2nd function will get called.
Controller
self.fetchAllTerminals = function() {
console.log('Controller');
AdminService.fetchAllTerminals()
.then(function(data) {
self.terminals = data;
}, function(error) {
console.error('Error while fetching Terminals');
});
};
