Question

我在struts2.3 ::

中有以下代码

SessionEvent se = new SessionEvent();

se.setSessionID(session.getId());

se.setUserID(user.getUserId());

session.setAttribute("SessionEvent", se);**


Map attributes = ActionContext.getContext().getSession();

attributes.put("USER", user);  // user is a serialized object

attributes.put("ID", 0);

ActionContext.getContext.setSession(attributes);

CustomSessionManager cst = new CustomSessionManager();

cst.setUserID(user.getUserId());

cst.setUserMachineIP(req.getRemoteHost());

cst.setUsersessionId(session.getId());

session.setAttribute("boundUnboundUser", cst);


SessionEvent And CustomSessionManager are Serialized Listener classes ::

public class SessionEvent implements HttpSessionBindingListener, Serializable
{

     public void valueBound(HttpSessionBindingEvent arg0)
     {

     }
     public void valueUnbound(HttpSessionBindingEvent arg1)
     {
     }
}




public class CustomSessionManager implements HttpSessionBindingListener, Serializable
{

     public void valueBound(HttpSessionBindingEvent arg0)
     {

     }
     public void valueUnbound(HttpSessionBindingEvent arg1)
     {
     }
}

现在的问题是，在复制时，DeltaManager能够复制SessionEvent和CustomSessionManager对象，但无法重新复制用户对象。现在，如果我更改代码序列并将会话代码放在会话事件之上，则会复制用户对象，但自定义会话管理器不会。不确定这是否是我的代码中的问题或者tomcat 7中Delta Manager的行为存在问题。我也标记了我的Web应用程序。我的tomcat接收器端口也不同。我正在使用粘性会话。以下是群集的server.xml配置我还在server.xml文件中的Engine标记内指定了jvmRoute属性。我使用mod_proxy_balancer进行负载均衡

会话属性未在tomcat 7群集中正确复制
