使用套接字发送对象时的连接休息

Question

我正在编写一个简单的程序，以使用TCP协议将对象表单服务器发送到客户端。我正在使用ObjectInputStream和ObjectOutputStream发送和接收对象。我在互联网上完全按照一些示例代码进行操作，但仍然出现此错误。这是我的代码。希望你们能帮助我

客户：

public class Client {
private Socket socket;
private ObjectInputStream receiveWeather;

public Client() {
    try {
        socket = new Socket("localhost", 4000);
        receiveWeather = new ObjectInputStream(socket.getInputStream());
        Weather w = null;
        try {
            w = (Weather) receiveWeather.readObject();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
        System.out.println(w.getDescription());
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public static void main(String[] args) {
    new Client();
}

}

服务器：

public class Server {
ServerSocket server;
ObjectOutputStream sendWeather;
Socket socket;
Weather w;

public Server() {
    try {
        server = new ServerSocket(4000);
        socket = server.accept();
        sendWeather = new ObjectOutputStream(socket.getOutputStream());
        w = WeatherInfo.getWeatherInfo("Ha Noi");          // this line just get object w from my function 
        sendWeather.writeObject(w);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public static void main(String[] args) {
    new Server();
}

}
