多次发送自定义对象后，Kryonet断开连接

Question

我正在学习KryoNet的一些网络知识，并且遇到了以下问题：当我从服务器向客户端发送对象时，它可以很好地发送并且可以读取它，但是当我再次发送它时，出现此错误。

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：

Answer 1

您是否尝试过以收到的方法检查从服务器获取的值？

我认为可能是这种情况，因为您正在实现Serializable接口，因此数据正在被序列化，并且当您尝试将其从整数转换为String时，会引起问题。

尝试反序列化收到的数据，看看会发生什么。
