请求被拒绝,因为没有找到angularjs和spring mvc的多部分边界

我试图使用angular js和spring mvc上传多个=“true”的多个输入类型文件,但我从服务器获得异常是“请求被拒绝,因为没有找到多部分边界”

在这里,我将把我的代码放在下面

我的jsp是


这里我是在点击添加后从角度控制器生成输入元素,并在“”中生成输入控件.
我的角度控制器是

'use strict';
var App = angular.module('TechnoBlogs',['ngRoute','ui.router']);
var $injector = angular.injector(['ng']);
App.config(['$httpProvider',function ($httpProvider) {    
    /*$httpProvider.defaults.headers.post['Content-Type'] = 'application/json; charset=UTF-8';*/
}],['$routeProvider',function($routeProvider){
    $routeProvider.
    when('/create',{
       templateUrl: '/',controller: 'controller'
});
 }]);
var currentg1=0;
var controller = function($scope,$http,fileService){
$scope.blog = [];
/*var currentg1=0;*/
$scope.blog.desc=[];
$scope.blog.desccode=[];
$scope.blog.descimg=[];
$scope.add=function(){
var $div = angular.element("required='required'>

我的弹簧控制器是

@RequestMapping(value="/saveblog",method=RequestMethod.POST,headers = "'Content-Type': 'multipart/form-data'")
public void saveblog(MultipartHttpServletRequest request,HttpServletResponse response)
{
    System.out.println("in multipart ");
    Iterator

我也为multipart创建一个bean

  

之后仍然有例外
我的回复标题是

最佳答案
也许这link会帮助你.您缺少的是内容标题.
从链接的答案：


Angular will POST as JSON even if you set the Content-Type to the correct value multipart/form-data. So we must transform our request manually to the correct data. … [using] a transformRequest function that does nothing as returning your original FormData … like this:

$http({
    method: 'POST',url: 'newDocument',headers: {'Content-Type': 'multipart/form-data'},data: formData,transformRequest: function(data,headersGetterFunction) {
        return data; // do nothing! FormData is very good!
    }
})
编辑：您能告诉我们您的HTTP响应和/或请求吗？
