Javascript REST上载Excel文件：POI库拒绝包含多部分边界的文件

我正在尝试用AngularJS和REST（Jersey）上传excel（.xlsx）文件。多部分边界将添加到REST中接收的文件中，apache POI库将其作为无效文件拒绝，但出现以下异常。这个问题的解决方案是什么

org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13]

    When I add @FormDataParam instead of @RequestParam I get the following   exception

角度片段：

    angular.module(appName).controller('fileUploadController',
    [ '$scope', 'fileUpload', function($scope, fileUpload) {

        $scope.uploadFile = function() {
            var file = $scope.myFile;
            console.log('file is ');
            console.dir(file);
            var uploadUrl = "myurl";
            fileUpload.uploadFileToUrl(file, uploadUrl);
        };

    } ]);

angular.module(appName).directive('fileModel', [ '$parse', function($parse) {
return {
    restrict : 'A',
    link : function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function() {
            scope.$apply(function() {
                modelSetter(scope, element[0].files[0]);
            });
        });
    }

angular

    .service(

            [

                    function($http) {
                        this.uploadFileToUrl = function(file, uploadUrl) {
                            var fd = new FormData();
                            //
                            fd.append('file', file);
                            $http

                                    }).error(function() {
                                    });
                        }
                    } ]);

这个问题与下面链接中的问题类似，只是它特定于C#

注释应该是

FormDataParam

，而不是

RequestParam

。如果仍然出现错误，请通过将文件写入临时位置来验证是否接收到该文件。当文件内容为空时，通常会出现此错误，在您的情况下更可能出现此错误

您可能应该在问题中添加java代码这里有一个链接，显示如何使用web服务上载文件。。。希望对你有帮助@RC。嗨，我已经添加了所有的细节。这是我关于stackoverflow的第一个问题，对不起。我正在获取边界后的数据，您可以在图像中看到它。我在本地复制了文件，并验证了边界内的数据是否相同。在“fileUpload”方法中，您是否将文件写入了临时位置，并且能够在没有错误的情况下打开它？关于FormDataParam的错误，您正在使用哪个版本的Jersey？我知道了。我正在使用以下Jersey JAR。jersey-bundle-1.19.jar jersey-core-1.19.jar jersey-multipart-1.19.jar
