Socket 多线程简例

多线程服务端，单独线程处理客户端连接，多个客户端之间不会阻塞

服务器端：

public class Server {

	ServerSocket serverSocket;
	Socket socket;

	public Server() throws IOException {
		serverSocket = new ServerSocket(10086);
		while (true) {
			socket = serverSocket.accept();
			// 启动多线程处理 socket
			new SocketHandler(socket).start();
		}
	}

	public static void main(String[] args) {
		try {
			new Server();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

}

Socket多线程处理类：

public class SocketHandler extends Thread {

	private Socket socket;

	public SocketHandler(Socket socket) {
		this.socket = socket;
	}

	@Override
	public void run() {
		try {
			accept(this.socket);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	private void accept(Socket socket) throws IOException {
		BufferedReader socketIn = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		String msg = socketIn.readLine();
		System.out.println("Client: " + msg);
		socketIn.close();
	}

}

客户端：

public class Client {

	Socket socket;

	public Client() throws UnknownHostException, IOException {
		// 连续发送
		while (true) {
			send();
		}
	}

	private void send() throws IOException {
		socket = new Socket("localhost", 10086);
		PrintWriter socketOut = new PrintWriter(socket.getOutputStream());
		System.out.print("Say: ");
		BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
		socketOut.write(input.readLine());
		socketOut.close();
	}

	public static void main(String[] args) {
		try {
			new Client();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

}
