完全参考java8的开发文档写的文件读写

    public static void main(String[] args) throws IOException {
        String path = "D:\\project\\luotuo-server\\src\\test\\java\\com\\manageSystem\\project\\lt\\service\\impl\\db_dump.sql";
        File file = new File(path);
        //151382

        InputStream inputStream = new  FileInputStream(file);
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
        String line = bufferedReader.readLine();
        Stream<String> lines = bufferedReader.lines();
        lines = lines.limit(151382);

        FileOutputStream fileOutputStream = new FileOutputStream("a.txt");
//        BufferedWriter writer = new BufferedWriter();
        try {
        lines.forEach(p->{
           //写数据到文件
            try {
                fileOutputStream.write(p.getBytes());
                fileOutputStream.write("\r\n".getBytes());
            } catch (IOException e) {
                e.printStackTrace();
            }

            System.out.println("haha");
        });

        } finally {
            if(fileOutputStream != null){
                fileOutputStream.close();
            }
            if(bufferedReader != null) {
                bufferedReader.close();
            }
            if (inputStreamReader != null) {
                inputStreamReader.close();
            }
            if(inputStream != null ) {
                inputStream.close();
            }
            System.out.println("chegn");
        }


    }
