JavaWeb实现多文件上传及zip打包下载

 
 上传资料

var formData = new FormData($("#uploadForm")[0]);
formData.append("foldName", "datumList"); //设置父级文件夹名称

formData.append("oderCode", selfOrderCode);
formData.append("datumType", datumType);
$.ajax({
 type: "POST",
 data: formData,
 url: "order/datumList/batchInsertDatumLists",
 contentType: false,
 processData: false,
 success: function (result) {
 if (result.success) {

  //清空框文件内容
  $("#fileImage").val("");
  var obj = document.getElementById('fileImage');
  obj.outerHTML = obj.outerHTML;

  refreshDatumList();
  showSuccessToast(result.message);
 } else {
  showWarningToast(result.message);
 }
 },
 error: function () {
 showErrorToast('请求失败！')
 }
});

MultipartHttpServletRequest mRequest = (MultipartHttpServletRequest) request;
List files = mRequest.getFiles("fileImage");

 

 
 
 批量下载
 

//批量下载
function batchDatumListDownLoad() {
 var param = {};
 param.datumType = $("#datumTypeQ").val();
 if (param.datumType == -1) {
 param.datumType = null; //查询所有
 }
 param.orderCode = selfOrderCode;

 $("#uploadForm input[name=orderCode]").val(param.orderCode);
 $("#uploadForm input[name=datumType]").val(param.datumType);

 var form = $("#uploadForm")[0];
 form.action = "order/datumList/batchDownLoadDatumList";
 form.method = "post";
 form.submit();//表单提交
}

public void batchDownLoadDatumList(DatumListVo datumListVo, HttpServletResponse response) {
 try {
 //查询文件列表
 List voList = datumListService.queryDatumLists(datumListVo);

 //压缩文件
 List files = new ArrayList<>();
 for (DatumListVo vo : voList) {
  File file = new File(vo.getDatumUrl());
  files.add(file);
 }

 String fileName = datumListVo.getOrderCode() + "_" + datumListVo.getDatumType() + ".zip";
 //在服务器端创建打包下载的临时文件
 String globalUploadPath = "";
 String osName = System.getProperty("os.name");
 if (osName.toLowerCase().indexOf("windows") >= 0) {
  globalUploadPath = GlobalKeys.getString(GlobalKeys.WINDOWS_UPLOAD_PATH);
 } else if (osName.toLowerCase().indexOf("linux") >= 0 || osName.toLowerCase().indexOf("mac") >= 0) {
  globalUploadPath = GlobalKeys.getString(GlobalKeys.LINUX_UPLOAD_PATH);
 }
 String outFilePath = globalUploadPath + File.separator + fileName;
 File file = new File(outFilePath);
 //文件输出流
 FileOutputStream outStream = new FileOutputStream(file);
 //压缩流
 ZipOutputStream toClient = new ZipOutputStream(outStream);
 //设置压缩文件内的字符编码，不然会变成乱码
 toClient.setEncoding("GBK");
 ZipUtil.zipFile(files, toClient);
 toClient.close();
 outStream.close();
 ZipUtil.downloadZip(file, response);

 } catch (Exception e) {
 e.printStackTrace();
 }
