non serializable session websocket java ee

问题

I write a ExchangeMoney class implements Serializable interface . This class has Session (javax.websocket.Session) property. See code below:

import javax.websocket.Session;
import javax.websocket.EncodeException;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.io.Serializable;
...
public class ExchangeMoney implements Serializable {

    private static final long serialVersionUID = -4363184570862565571L;

    private static final Logger logger = Logger.getLogger("ExchangeMoney ");

    private Session session;

    ....
}

Error due to session field non serializable. How to resolve this problem.

回答1:

Check this post. Java Serialization with non serializable parts

Basically you can extend session and implement serializable and override writeObject and readObject methods and try to persist and read the values you are interested in.

Reconsider the design. Why does a serializable object requires a websocket session inside it and if it is required, shouldn't it be transient?
