本文提供了一个简单的示例，展示如何通过Java代码实现从服务器下载指定的文件，包括文档模板和Excel模板。具体步骤包括获取输入流、读取文件内容、设置HTTP响应头，并返回包含文件数据的响应实体。

/**
   * 下载用户信息填写模板使用说明
   * @param httpServletResponse response对象
   * @return
   * @throws Exception
   */
   @RequestMapping("/downloadReadFile")
   public ResponseEntity<byte[]> downloadReadFile(HttpServletResponse httpServletResponse) throws Exception {
       byte [] body = null;
       //获得输入流
       InputStream in = this.getClass().getClassLoader().getResourceAsStream("excel/说明.docx");
       body = new byte[in.available()];
       in.read(body);

       HttpHeaders headers = new HttpHeaders();
       headers.add("Content-Disposition", "attachment;filename=" + new String("说明.docx".getBytes(), "ISO-8859-1"));
       HttpStatus statusCode = HttpStatus.OK;
       ResponseEntity<byte[]> response = new ResponseEntity<byte[]>(body, headers, statusCode);
       return response;
   }

   /**
   * 下载用户信息填写模板
   * @param httpServletResponse response对象
   * @return
   * @throws Exception
   */
   @RequestMapping("/downloadExcel")
   public ResponseEntity<byte[]> downloadExcel(HttpServletResponse httpServletResponse) throws Exception {
       byte [] body = null;
       //获得输入流
       InputStream in = this.getClass().getClassLoader().getResourceAsStream("excel/用户模板.xls");
       body = new byte[in.available()];
       in.read(body);

       HttpHeaders headers = new HttpHeaders();
       headers.add("Content-Disposition", "attachment;filename=" + new String("用户模板.xls".getBytes(), "ISO-8859-1"));
       HttpStatus statusCode = HttpStatus.OK;
       ResponseEntity<byte[]> response = new ResponseEntity<byte[]>(body, headers, statusCode);
       return response;
   }
