Angular.js前臺傳list數組由后臺spring MVC接收數組示例代碼

$scope.saveScore = function () {

 $scope.userScoreList = new Array();//自定義數組

 angular.forEach ($scope.records, function (record, index) {

 

 if (record.score != null) {

 $scope.userScoreModel = {'userAnswerId': null,'score': null};//自定義對象結構

 $scope.userScoreModel.userAnswerId = record.userAnswerId;//賦值

 $scope.userScoreModel.score = record.score;

 

 $scope.userScoreList.push($scope.userScoreModel);//把對象封裝在集合中

 debugger;

 }

 });

 

 if ($scope.userScoreList != null && $scope.userScoreList.length > 0) {

 var fd = new FormData();// 使用angularJS的FormData封裝要傳送的數據

 var userScoreRecords = angular.toJson($scope.userScoreList);//把對象(集合)轉換為json串

 fd.append('userScoreRecords', userScoreRecords);//參數放入formData中

 debugger;//使用 debugger模式查看傳值情況

 $http.post('/reviewProcess/save', fd, { //使用post方法 傳送formdata對象

 transformRequest: angular.identity, //使用angular傳參認證

 headers: {

 'Content-Type': undefined //設置請求頭

 }

 })

 .success(function (data){

 toastr.success("success");

 })

 .error(function (data) {

 toastr.success("failed");

 });

 }

}; 

@ResponseBody

 @RequestMapping(value = "/reviewProcess/save", method = RequestMethod.POST)

 public void saveUserScore (@RequestParam("userScoreRecords") String userScoreRecords) { //使用requestparam接收前臺傳送的json串

 System.out.println(userScoreRecords);

 ObjectMapper mapper = new ObjectMapper(); // 使用fastJson的ObjectMapper反序列化json串為對象

 UserScoreModel record = null;

 try {

 JSONArray jsonArray = new JSONArray (userScoreRecords); //在后臺把json串轉換為json數組

 for (int i =0; i < jsonArray.length(); i++) {

 record = mapper.readValue(jsonArray.getJSONObject(i).toString(), UserScoreModel.class); //獲取json數組的json對象并且反序列化為對應的對象

 System.out.println(record); // 得到對象后后臺即可操作

 }

 } catch (Exception e) {

 logger.error(e.getMessage(), e);

 }

 }
