BIO通讯

传统阻塞io模型

代码：

public class BioServerSocket {

    public static void main(String[] args) throws IOException {

        ServerSocket serverSocket = new ServerSocket(6666);
        ExecutorService executorService = Executors.newFixedThreadPool(10);
        System.out.println("1.启动服务");
        while (true) {
            // 监听客户端连接
            System.out.println("2.等待连接...");
            Socket socket = serverSocket.accept();
            executorService.execute(new Runnable() {
                @Override
                public void run() {
                    try {
                        System.out.println("建立连接，开启线程处理socket...");
                        handle(socket);
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            });
        }
    }

    private static void handle(Socket socket) throws IOException {
        try {
            InputStream inputStream = socket.getInputStream();
            byte[] bytes = new byte[1024];
            while (true) {
                int read = inputStream.read(bytes);
                if (read != -1) {
                    System.out.print(new String(bytes, 0, read));
                } else {
                    break;
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            socket.close();
        }
    }
}

windows下验证：
windows开启telnet命令

• telnet为黑框，不显示输入的字符串
