我正在使用 KryoNet 学习一些网络知识，我遇到了一个问题，当我将对象从服务器发送到客户端时，它发送它就很好，我可以阅读它，但是当我再次发送它时，我得到了这个错误。

服务器：

server = new Server();
    Kryo kryo = server.getKryo();
    kryo.register(Command.class, new JavaSerializer());
    server.start();
    try {
        server.bind(54555, 54777);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

客户：

client = new Client();
    Kryo kryo = client.getKryo();
    kryo.register(Command.class, new JavaSerializer());
    client.setKeepAliveTCP(2000);
    client.start();
    try {
        client.connect(5000, "192.168.1.5", 54555, 54777);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    client.addListener(new Listener() {
        public void connected(Connection connection){

        }
        public void received (Connection connection, Object object) {
            if(object instanceof Command){
                Command c = (Command) object;
                textField.setText(Integer.toString(c.getTime()));
            }
        }
     });

我的课：

public class Command implements Serializable{

private static final long serialVersionUID = 1L;
private int time;

public Command(int time) {
    setTime(time);
}

public int getTime() {
    return time;
}

public void setTime(int time) {
    this.time = time;
}

}

堆栈跟踪：

您是否尝试过在接收方法中检查您从服务器获得的值？

我认为可能是因为您正在实现 Serializable 接口，因此数据正在被序列化，当您尝试将其从整数转换为 String 时，它会导致问题。

尝试反序列化您收到的数据，看看会发生什么。
