Dropzone多张图片 上传问题

图片传不过来 uploadMultiple: false,传单张可以 求教？

Dropzone.options.tabPackageImg = {
// autoProcessQueue: false,//自动上传
maxFilesize: 5.0, // MB
maxFiles: 3,//一次性上传的文件数量上限
acceptedFiles: "image/*",
thumbnailWidth: 300,
thumbnailHeight: 300,
addRemoveLinks: true,//添加移除文件
dictDefaultMessage: "点击或拖拽上传图片",
dictCancelUploadConfirmation: '你确定要取消上传吗？',
dictMaxFilesExceeded: "您一次最多只能上传{{maxFiles}}个文件",
dictFileTooBig: "文件过大({{filesize}}MB). 上传文件最大支持: {{maxFilesize}}MB.",
dictResponseError: '文件上传失败!',
dictInvalidFileType: "你不能上传该类型文件,文件类型只能是图片类型。",
dictCancelUpload: "取消上传",
dictRemoveFile: "重新上传",
uploadMultiple: true,
// Dropzone settings
init: function () {
var myDropzone = this;
// this.element.querySelector("button[type=submit]").addEventListener("click", function (e) {
// e.preventDefault();
// e.stopPropagation();
// myDropzone.processQueue();
// });
this.on("sendingmultiple", function () {
});
this.on("successmultiple", function (files, response) {
});
this.on("errormultiple", function (files, response) {
});
},

                    e.printStackTrace();
                }
            }

        tabPackage.setPackageimages(packageimages);


        tabPackageService.update(tabPackage);

Spring 有个MultipartRequest 用这个去读取文件

Sring后台还有个设置文件大小的上限的，记得加上
