Angular.js前台传list数组由后台spring MVC接收数组示例代码

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");

});

}

};

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);

}

}
