Java批量导出word压缩后的zip文件案例

一、js代码，由于参数比较大所以利用form表单使用post导出


 function export_word(){
  var selectedRows = $("#dg").datagrid("getSelections");
  if (selectedRows.length==0) {
   showAlertWarning("请选择一条的信息...");
   return;
  }
  if (selectedRows.length > 1) {//批量导出压缩文件
   var id = "";
   for (var i = 0; i < selectedRows.length; i++) {
    var row = selectedRows[i];
    id += row.id+"name"+row.user_name+"@@";
   }
   layer.confirm('请选择要导出考核表的类型？', {
    btn: ['次数','具体条目'] //按钮
   }, function(index){
    postExportFile({"id":id,"type":0},"jee/AssessGradeSumC/exportWordsZip");
    layer.close(index);
   }, function(index){
    postExportFile({"id":id,"type":1},"jee/AssessGradeSumC/exportWordsZip");
   });
  } else {//导出单个
   layer.confirm('请选择要导出考核表的类型？', {
    btn: ['次数','具体条目'] //按钮
   }, function(index){
    window.location.href= "jee/AssessGradeSumC/exportWord?id="+selectedRows[0].id;
    layer.close(index);
   }, function(index){
    window.location.href= "jee/AssessGradeSumC/exportWordForSpecific?id="+selectedRows[0].id;
   });
  }
 }
 function postExportFile(params, url) { //params是post请求需要的参数，url是请求url地址
  var form = document.createElement("form");
  form.style.display = 'none';
  form.action = url;
  form.method = "post";
  document.body.appendChild(form);
  for(var key in params){
   var input = document.createElement("input");
   input.type = "hidden";
   input.name = key;
   input.value = params[key];
   form.appendChild(input);
  }
  form.submit();
  form.remove();
 }

二、controller代码（读完压缩文件后删除文件）


 /**
 *
 * @Description 考核成绩汇总考核表批量导出压缩
 * @Fcunction exportWordsZip
 * @param response
 * @return ReturnDatas
 *
 */
 @ResponseBody
 @SystemControllerLog(description = "考核成绩汇总考核表批量导出压缩")
 @RequestMapping(value = "exportWordsZip")
 public ReturnDatas exportWordsZip(HttpServletResponse response, String id, String type) {
 ReturnDatas returnDatas = ReturnDatas.getSuccessReturnDatas();
 try {
 response.setCharacterEncoding("UTF-8");
 response.setContentType("application/msexcle");
 response.setHeader("content-disposition", "attachment;filename=" + new String("考核成绩汇总表".getBytes("gb2312"), "ISO8859-1") + ".zip");
 String fileUrl = assessGradeSumService.exportWordsZip(id,type);
 OutputStream outputStream = response.getOutputStream();
 BufferedInputStream bis = new BufferedInputStream(new FileInputStream(fileUrl));;
 BufferedOutputStream bos = new BufferedOutputStream(outputStream);
 byte[] buff = new byte[2048];
 int bytesRead;
 while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
 bos.write(buff, 0, bytesRead);
 }
 bis.close();
 bos.close();
 outputStream.close();
 File zip = new File(fileUrl);
 if (zip.exists() && zip.isFile()) {
 zip.delete();
 }
 return returnDatas;
 } catch (Exception e) {
 e.printStackTrace();
 LogUtil.error("考核成绩汇总考核表批量导出压缩异常：" + e.getMessage(), e);
 returnDatas.setStatus(ReturnDatas.ERROR);
 returnDatas.setMessage("考核成绩汇总考核表批量导出压缩异常。");
 }
 return returnDatas;
 }

三、实现类代码，其中exportWord()和exportWordForSpecific()都是具体的word导出方法，生成zip压缩文件后删除word文件，ZipUtils是压缩文件工具类


/**
 *
 * @Fcunction exportWordsZip
 * @param id
 * @param type
 * @return String
 *
 */
 @Override
 public String exportWordsZip(String id, String type)throws Exception{
 String[] ids = id.split("@@");
 List<File> fileList = new ArrayList<>();
 String url = "C:\\";
 for (int i = 0; i < ids.length; i++) {
 String id_name = ids[i];
 String id_value = id_name.split("name")[0];
 String name = id_name.split("name")[1];
 String docUrl = url + name + ".doc";
 fileList.add(new File(docUrl));
 XWPFDocument workbook = null;
 if ("0".equals(type)) {//按次
 workbook = exportWord(id_value);
 } else {//表单条目
 workbook = exportWordForSpecific(id_value);
 }
 FileOutputStream out = new FileOutputStream(docUrl);
 workbook.write(out);
 }
 String zipUrl = url+"考核成绩汇总表.zip";
 FileOutputStream fos = new FileOutputStream(new File(zipUrl));
 ZipUtils.toZip(fileList, fos);
 for (File out:fileList) {
 if (out.exists() && out.isFile()) {
 out.delete();
 }
 }
 return zipUrl;
 }
