angularJS前台传list数组,后台springMVC接收数组

有时候需要在前台自定义对象,然后把对象封装在list中,在传送到后台,这样的思想也比较合理

1. 前台代码

	$scope.saveScore = function () {
$scope.userScoreList = new Array();//自定义数组
angular.forEach ($scope.records, function (record, index) { if (record.score != null) {
$scope.userScoreModel = {'userAnswerId': null,'score': null};//自定义对象结构
$scope.userScoreModel.userAnswerId = record.userAnswerId;//赋值
$scope.userScoreModel.score = record.score; $scope.userScoreList.push($scope.userScoreModel);//把对象封装在集合中
debugger;
}
}); if ($scope.userScoreList != null && $scope.userScoreList.length > 0) {
var fd = new FormData();// 使用angularJS的FormData封装要传送的数据
var userScoreRecords = angular.toJson($scope.userScoreList);//把对象(集合)转换为json串
fd.append('userScoreRecords', userScoreRecords);//参数放入formData中
debugger;//使用 debugger模式查看传值情况
$http.post('/reviewProcess/save', fd, { //使用post方法 传送formdata对象
transformRequest: angular.identity, //使用angular传参认证
headers: {
'Content-Type': undefined //设置请求头
}
})
.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接收前台传送的json串
System.out.println(userScoreRecords);
ObjectMapper mapper = new ObjectMapper(); // 使用fastJson的ObjectMapper反序列化json串为对象
UserScoreModel record = null;
try {
JSONArray jsonArray = new JSONArray (userScoreRecords); //在后台把json串转换为json数组
for (int i =0; i < jsonArray.length(); i++) {
record = mapper.readValue(jsonArray.getJSONObject(i).toString(), UserScoreModel.class); //获取json数组的json对象并且反序列化为对应的对象
System.out.println(record); // 得到对象后后台即可操作
}
} catch (Exception e) {
logger.error(e.getMessage(), e);
}
}
