angularJS前台傳list數組，后台springMVC接收數組

有時候需要在前台自定義對象，然后把對象封裝在list中，在傳送到后台，這樣的思想也比較合理

1. 前台代碼

	$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");
			});
		}
	};

　　2. 后台接收

 

  @ResponseBody
    @RequestMapping(value = "/reviewProcess/save", method = RequestMethod.POST)
    public void saveUserScore (@RequestParam("userScoreRecords") String userScoreRecords) { //使用requestparam接收前台傳送的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); //在后台把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對象並且反序列化為對應的對象
                System.out.println(record); // 得到對象后后台即可操作
            }
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
        }
    }
