java xlsx文件在http请求中发送时已损坏/为空（0字节）
我正在通过http请求发送xlsx文件，但该文件已损坏。 我只是不明白为什么文件在发送时会损坏。 请帮忙，我是新手
以下是jsp文件：

angular.module('myApplication',["ngRoute"]).

.controller('myController',['$scope','$http',
function($scope,$http) {
$scope.message = "Test message";
$scope.filesChanged = function(elm) {
$scope.files=elm.files;
$scope.$apply();

$scope.upload = function() {

angular.forEach($scope.files,function(file){
fd.append('file',file);
})
$http.post('http://localhost:80/simple-web-services/uploadQuestions', fd,{

.success(function(d){
console.log(d);

};
}
])
.config(function($routeProvider) {
$routeProvider

.when("/upload", {

<body ng-controller="myController">
<nav class="navbar navbar-default">

<ul class="nav navbar-nav">

<li><a href="#download">Download Question Template</a></li>
</ul>
</div>
</nav>
<div ng-view></div>
</body>
</html>
这是表格：（uploadQuestion.html）
<form method="post">
<input type="file"
file-input="files"
multiple></input>
<button ng-click="upload()"> Upload </button>
<li ng-repeat="file in files" >{{file.name}} </li>
</form>
例外情况是 JAVAlang.RuntimeException:org。阿帕奇。cxf。拦截器。错误：您的InputStream既不是OLE2流，也不是OOXML流
