java 導出word 並下載

記錄一下導出操作

源碼：

    /************
     * 導出word 並下載
     * @param id   房號記錄編號
     * ***********************/
    @RequestMapping("/exportAgent")
    @ResponseBody
    public void execute(String id, HttpServletRequest request,HttpServletResponse resp) throws Exception {
        log.info("導出word 並下載==>>[id="+id+"]");
        String path = request.getSession().getServletContext().getRealPath("/ExportWord");
        String filename = exportSimpleWord(id, request);// 生成文件的文件名稱 這個需要動態的獲取
        OutputStream out;// 輸出響應正文的輸出流
        InputStream in;// 讀取本地文件的輸入流
        // 獲得本地輸入流
        File file = new File(path + "\\" + filename);
        in = new FileInputStream(file);
        // 設置響應正文的MIME類型
        resp.setContentType("Content-Disposition;charset=GB2312");
        resp.setHeader("Content-Disposition", "attachment;" + " filename="    + new String(filename.getBytes(), "ISO-8859-1"));
        // 把本地文件發送給客戶端
        out = resp.getOutputStream();
