Spring MVC-AngularJS-文件上传-org.apache.commons.fileupload.FileUploadException

Question

我有一个Java Spring MVC Web应用程序作为服务器。并且基于AngularJS的应用程序作为客户端。

在AngularJS中，我必须上传文件并发送到服务器。

这是我的 html

<form ng-submit="uploadFile()" class="form-horizontal" enctype="multipart/form-data">
   <input type="file" name="file" ng-model="document.fileInput" id="file" onchange="angular.element(this).scope().setTitle(this)" />
   <input type="text" class="col-sm-4" ng-model="document.title" id="title" />
   <button class="btn btn-primary" type="submit">
         Submit
    </button>
</form>

这是我的 UploadController.js

'use strict';

var mainApp=angular.module('mainApp', ['ngCookies']);

mainApp.controller('FileUploadController', function($scope, $http) {

    $scope.document = {};

        $scope.setTitle = function(fileInput) {

        var file=fileInput.value;
        var filename = file.replace(/^.*[\\\/]/, '');
        var title = filename.substr(0, filename.lastIndexOf('.'));
        $("#title").val(title);
        $("#title").focus();
        $scope.document.title=title;
    };

        $scope.uploadFile=function(){
             var formData=new FormData();
         formData.append("file",file.files[0]);
                   $http({
                  method: 'POST',
                  url: '/serverApp/rest/newDocument',
                  headers: { 'Content-Type': 'multipart/form-data'},
                  data:  formData
                })
                .success(function(data, status) {                       
                    alert("Success ... " + status);
                })
                .error(function(data, status) {
                    alert("Error ... " + status);
                });
      };
});

它要发送到服务器。这是我的 DocumentUploadController.java

@Controller
public class DocumentUploadController {

    @RequestMapping(value="/newDocument", headers = "'Content-Type': 'multipart/form-data'", method = RequestMethod.POST)
    public void UploadFile(MultipartHttpServletRequest request, HttpServletResponse response) {

        Iterator<String> itr=request.getFileNames();

        MultipartFile file=request.getFile(itr.next());

        String fileName=file.getOriginalFilename();
        System.out.println(fileName);
    }
}

运行此命令时，出现以下异常

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found] with root cause

在我的 applicationContext.xml中 ，我提到了

<bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="100000" />
    </bean>

我在用

spring - 3.2.1.RELAESE
commons-fileupload - 1.2.2
commons-io - 2.4

如何解决呢？

如果有人打电话给我，如何从angularJS发送文件和其他表单数据并将其获取到服务器中，那将是很棒的。

我的服务器在其他8080端口上运行。我使用的是eoman，grunt和bower。太瘦了gruntfile.js我已经提到了服务器端口。因此它进入服务器并运行，并引发异常

Answer 1

即使更新了transformRequest之后，我也面临着同样的问题并遇到了同样的问题。“有些情况下，标题边界似乎设置不正确。

按照http://uncorkedstudios.com/blog/multipartformdata-file-upload-with-
html" target="_blank">angularjs
，此问题已解决。从该位置提取…。

通过设置’Content-Type’：未定义，浏览器为我们将Content-Type设置为multipart / form-
data并填写正确的边界。手动设置“内容类型”：multipart / form-data将无法填写请求的边界参数。

不确定这是否对任何人都有帮助，但也许可以使查看此帖子的人变得容易…至少，它使难度降低。
