下載excel模板：

此示例簡單介紹下載excel模板

 public void downloadExcel(HttpServletResponse response)throws IOException{
        //獲取輸入流，原始模板位置
//        String  filePath = getClass().getResource("/template/xxxxxx.xlsx").getPath();
//        InputStream bis = new BufferedInputStream(new FileInputStream(new File(filePath)));
 


//伺服器資源地址
        URL url = new URL(“模板資源地址”);
        InputStream bis = new BufferedInputStream(url.openStream());

        //設定下載檔名稱
        String filename = "XX模板.xlsx";
        //轉碼，避免中文檔名亂碼
        filename = URLEncoder.encode(filename,"UTF-8");
        //設定檔案下載頭
        response.
 
addHeader("Content-Disposition", "attachment;filename=" + filename);
        //設定ContentType型別，這樣設定，會自動判斷下載檔案型別
        response.setContentType("multipart/form-data");
        BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
        int len =
 
 0;
        while((len = bis.read()) != -1){
            out.write(len);
            out.flush();
        }
        out.close();
    }
