Socket通信

Server:

public class Server {

	public static void main(String[] args) throws Exception{
		
		ServerSocket server = new ServerSocket(9999);
		
		Socket socket = null;
		
		while(true){
		    socket = server.accept();
			LoginThread lt = new LoginThread(socket);
			new Thread(lt).start();
		}
		
		
		
	}
}

LoginThread：

public class LoginThread implements Runnable {

	private Socket socket;
	
	public LoginThread(Socket socket) {
		super();
		this.socket = socket;
	}

	@Override
	public void run() {
		// TODO Auto-generated method stub
		try {
			
			InputStream is = socket.getInputStream();
			ObjectInputStream ois = new ObjectInputStream(is);
			User user = (User) ois.readObject();
			OutputStream os = socket.getOutputStream();
			
			System.out.println("服务器收到User："+user);
			String temp = "";
			if("aaa".equals(user.getName())&&"aaa".equals(user.getPwd())){
				temp="登陆成功！！";
			}else{
				temp="登录失败";
			}
			os.write(temp.getBytes());
			
			is.close();
			ois.close();
			os.close();
			socket.close();
			
			
			
			} catch (Exception e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
	}

}

Client：

public class Client {
	public static void main(String[] args) throws Exception {
		Socket socket = new Socket("localhost",9999);
		OutputStream os = socket.getOutputStream();
		ObjectOutputStream oos = new ObjectOutputStream(os);
		
		Scanner sc = new Scanner(System.in);
		
		System.out.print("请输入名称：");
		String name = sc.next();
		System.out.print("请输入密码：");
		String pwd = sc.next();
		
		oos.writeObject(new User(name,pwd));
		
		InputStream is = socket.getInputStream();
		BufferedReader br = new BufferedReader(new InputStreamReader(is));
		
		System.out.println(br.readLine());
		
		br.close();
		is.close();
		sc.close();
		oos.close();
		os.close();
		socket.close();
		
	}
