    String encoding = "GBK";
    File file = new File("D:\\jz_activity_exchange_voucher-INSERT.txt");
    if (file.isFile() && file.exists()) { //判断文件是否存在
        InputStreamReader read = new InputStreamReader(
                new FileInputStream(file), encoding);//考虑到编码格式
        BufferedReader bufferedReader = new BufferedReader(read);
        String lineTxt = null;
        while ((lineTxt = bufferedReader.readLine()) != null) {
               System.out.println(lineTxt);         
         }       

        read.close();
    } else {
        System.out.println("找不到指定的文件");
        return new Success<>(false);
    }
} catch (Exception e) {
    System.out.println("读取文件内容出错");
    e.printStackTrace();
}
