[TOC] # 简介 我们这边用不断创建一个线程接收客户端发过来的消息,这样就不会阻塞 然后我们把消息处理的时候也不断的创建线程这样消息来的时候就不用等待阻塞在那边 # ServerBoot 服务端启动类 ~~~ public class ServerBoot { private static final int PORT = 8000; public static void main(String[] args) { Server server = new Server(PORT); server.start(); } } ~~~ # Server 服务端接收客户端消息类 ~~~ import java.io.IOException; import java.net.ServerSocket; import java.net.Socket; public class Server { private ServerSocket serverSocket; public Server(int port) { try { this.serverSocket = new ServerSocket(port); System.out.println("服务端启动成功，端口:" + port); } catch (IOException exception) { System.out.println("服务端启动失败"); } } public void start() { new Thread(new Runnable() { @Override public void run() { doStart(); } }).start(); } private void doStart() { while (true) { try { Socket client = serverSocket.accept(); new ClientHandler(client).start(); } catch (IOException e) { System.out.println("服务端异常"); } } } } ~~~ # ClientHandler 处理客户端消息的类 ~~~ import java.io.IOException; import java.io.InputStream; import java.net.Socket; public class ClientHandler { public static final int MAX_DATA_LEN = 1024; private final Socket socket; public ClientHandler(Socket socket) { this.socket = socket; } public void start() { System.out.println("新客户端接入"); new Thread(new Runnable() { @Override public void run() { doStart(); } }).start(); } private void doStart() { try { InputStream inputStream = socket.getInputStream(); while (true) { byte[] data = new byte[MAX_DATA_LEN]; int len; while ((len = inputStream.read(data)) != -1) { String message = new String(data, 0, len); System.out.println("客户端传来消息: " + message); socket.getOutputStream().write(data); } } } catch (IOException e) { e.printStackTrace(); } } } ~~~ # Client 客户端发送消息类 ~~~ import java.io.IOException; import java.net.Socket; public class Client { private static final String HOST = "127.0.0.1"; private static final int PORT = 8000; private static final int SLEEP_TIME = 5000; public static void main(String[] args) throws IOException { final Socket socket = new Socket(HOST, PORT); new Thread(new Runnable() { @Override public void run() { System.out.println("客户端启动成功!"); while (true) { try { String message = "hello world"; System.out.println("客户端发送数据: " + message); socket.getOutputStream().write(message.getBytes()); } catch (Exception e) { System.out.println("写数据出错!"); } sleep(); } } }).start(); } private static void sleep() { try { Thread.sleep(SLEEP_TIME); } catch (InterruptedException e) { e.printStackTrace(); } } } ~~~
