Socket

客户端:

public class MyClient {
	public static void main(String[] args) {
		
		try {
			Socket s = new Socket("192.168.0.106",9090);
			OutputStream ops = s.getOutputStream();
			ops.write("gg".getBytes());
			ops.close();
		} catch (IOException e) {
			
			e.PRintStackTrace();
		}
		
	}
}
服务端:

public class MyServer {
	public static void main(String[] args) {
		try {
				ServerSocket serverSocket = new ServerSocket(9090);
				System.out.println("服务器开启");
				while(true){
				
					Socket socket = serverSocket.accept();
					new ServiceThread(socket);
				}
		} catch (IOException e) {
			
			e.printStackTrace();
		}
	}
}

服务端线程

public class ServiceThread implements Runnable{
	
	Socket socket;
	private InputStream iS;
	public ServiceThread(Socket socket){
		this.socket = socket;
		InetAddress address = socket.getInetAddress();
		System.out.println("---客户端连接:"+address+"---");
		try {
			iS = socket.getInputStream();
		} catch (IOException e) {
			
			e.printStackTrace();
		}
		new Thread(this).start();
	}
	
	@Override
	public void run() {
		while(true){
			try{
			String msg = MessageUtil.read(iS);
			System.out.println("客户端发送的消息:"+msg);
			Thread.sleep(200);
			}catch(Exception e){
				System.out.println("---客户端关闭连接---");
				break;
			}
		}
		
	}

}
信息的读与写的方法

public class MessageUtil {
	public static String read(InputStream iS){
				
				try {
					
					byte[] b = new byte[1024];//缓存数组(1k)
					int length = -1;
					String content = "";
					while((length = iS.read(b))!= -1){
						String result = new String(b,0,length);
						if("#end#".equals(result)){
							break;
						}else{
							content += result;
						}
					}
					return content;
				} catch (Exception e) {
					throw new RuntimeException();
				}
				
	}
	public static void write(OutputStream ops,String t){
		try {
			ops.write(t.getBytes());
			ops.write("#end#".getBytes());
		} catch (IOException e) {
			
			e.printStackTrace();
		}
			
	}
