使用Java IO实现客户端服务端
服务端监听端口
客户端连接服务端
客户端循环写数据到服务端
import java.io.IOException; import java.net.Socket; /** * @author ko */ 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(); } } }
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(); } } }
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"); } } } }
/** * @author ko */ public class ServerBoot { private static final int PORT = 8000; public static void main(String[] args) { Server server = new Server(PORT); server.start(); } }
