springMVC导出word模板的方法

本文实例为大家分享了springMVC导出word模板的具体代码，供大家参考，具体内容如下

controller 调用

@RequestMapping(value = "/exportWord")
public void exportWord(HttpServletResponse response, HttpServletRequest request) throws IOException {
  String templatePath = request.getServletContext().getRealPath("") + "/template/税源信息比对.docx";
  String fileName = new String("税源信息比对".getBytes("gb2312"), "ISO8859-1") + ".docx";
  /*数据*/
  Map<String, Object> params = new HashMap<String, Object>();
  params.put("${name}", "aaaa");
  params.put("${sex}", "bbbb");

  TempleWordUtil wordUtil = new TempleWordUtil();

  XWPFDocument doc;
  InputStream is = new FileInputStream(templatePath);
 // is = getClass().getClassLoader().getResourceAsStream(templatePath);
  doc = new XWPFDocument(is);  //只能使用.docx的

  wordUtil.replaceInPara(doc, params);
  //替换表格里面的变量
  wordUtil.replaceInTable(doc, params);
  OutputStream os = response.getOutputStream(); 

  response.setContentType("application/vnd.ms-excel");
  response.setHeader("Content-disposition", "attachment;filename=" + fileName); 

  doc.write(os); 

  wordUtil.close(os);
  wordUtil.close(is); 

  os.flush();
  os.close(); 

}
