将Jsp响应转换为JSON

Question

我有一个问题，因为我试图从angularjs中的jsp检索数据。这可行吗？如果没有..在角度js控制器中获取检索数据的其他方法是什么。任何人都可以帮我解决问题。我的守则如下......

    angular.module("myApp", []).controller('testController',['$scope', '$http', '$log', function($scope, $http, $log)
     {
                var stateNameHindi = "";
                var stateLandingPageUrl = "";
        $scope.ScopeObject = {
              states : [

             { name: "राज्य चुनें", Ename: "select", district: [{Hnname: 'जिला चुनें', DEname: "Select" }] },

                        $scope.CityData = JSON.parse(response);
                        alert("sing" + $scope.CityData);

                        $log.info(response);}

                        $scope.StateData =  JSON.stringify(response);
                        var data = JSON.parse($scope.CityData)
