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= 'https://www.haobala.com/bcjs/jee/AssessGradeSumC/exportWord?id='+selectedRows[0].id; layer.close(index); }, function(index){ window.location.href= 'https://www.haobala.com/bcjs/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; }
