JAVA 读取本地文本文件

 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();}
