新手个人笔记-java获取Excel模板并生成新的Excel导出

前端大概的样式:

模板:

效果:

HTML:

<span class="l" style="margin-left: 10px;"><a class="btn btn-primary radius" data-title="导出明细记录" onclick="downloadExcelDetails()" href="#"><i class="Hui-iconfont"></i> 导出明细记录</a>
</span>

JS：

//导出Excel公共方法function downloadExcelDetails() {var logmin = $("#logmin").val();var logmax = $("#logmax").val();var compname = $("#compname").val();var area_name = $("#p_status").val();var d_type = $("#d_type").val();//条件判断省略//.....window.location.href = "<%=basePath%>inspection/publicDownloadExcel.cyl?sDate="+ logmin +"&eDate="+ logmax +"&villageName="+ compname +"&area_name="+ area_name +"&d_type="+ d_type;}

控制层（根据个人需求修改，代码写的有点乱，没有什么设计模式，新手上路请多指教！）:

@ResponseBody@RequestMapping(value = "publicDownloadExcel")public void downloadExcelQueryData(HttpServletRequest request, HttpServletResponse response, String sDate, String eDate, String villageName, String d_type, String area_name, Authentication authentication) throws IOException {SessionUser sessionUser = (SessionUser) authentication.getPrincipal();String excelPathP = null;String excelNameP = null;Map<String, String> resultList = new HashMap<String, String>();//导出明细if (area_name != null && !area_name.equals("")) {//导出明细String templatefile = request.getServletContext().getRealPath("/");if (d_type != null && d_type.equals("0")) {templatefile += "excleTemplate/AreaTemplate.xlsx";//小区}if (d_type != null && d_type.equals("1")){templatefile += "excleTemplate/CompanyTemplate.xlsx";//单位}List<ljCheckBodyTarget> resultDetailsList = dailyInService.queryDetailsInfoBydateAndvillageName(sDate, eDate, villageName, d_type, area_name, sessionUser.getLevel(), sessionUser.getId());resultList = ExportExcelUtil.putInto1Excel(request.getServletContext(), null, resultDetailsList, templatefile, d_type);excelPathP = resultList.get("path");excelNameP = resultList.get("name");}//文件流的方式导出Exceltry {// 输出响应正文的输出流OutputStream out;// 读取本地文件的输入流InputStream in;// 获得本地输入流File file = new File("C:\\"+ excelPathP + excelNameP);in = new FileInputStream(file);// 设置响应正文的MIME类型response.setContentType("application/octet-stream;charset=UTF-8");String fileName = new String(excelNameP.getBytes("gb2312"), "iso8859-1");response.setHeader("Content-disposition", "attachment;filename=" + fileName);// 把本地文件发送给客户端out = response.getOutputStream();int byteRead = 0;byte[] buffer = new byte[512];while ((byteRead = in.read(buffer)) != -1) {out.write(buffer, 0, byteRead);}in.close();out.flush();out.close();} catch (Exception e) {e.printStackTrace();logger.error("文件下载出现异常", e); } }
