pushlet 应用到项目中 一 (修改SesssionManager,和Session类)

修改SesssionManager,和Session类使得sessionId是有意义的,一般改成用户id!

 

Session类添加一个方法:

/*** czp 新增方法,sessionId为用户id
	 * @param anId
	 * @param anEvent
	 * @return
	 * @throws PushletException
	 */
	public static Session create(String anId,Event anEvent) throws PushletException {
		Session session;
		try {
			session = (Session) Config.getClass(SESSION_CLASS, "nl.justobjects.pushlet.core.Session").newInstance();
		} catch (Throwable t) {
			throw new PushletException("Cannot instantiate Session from config", t);
		}
		// Init session
		session.id = anEvent.getField("userId");//sessionId为有意义的用户id
		session.controller = Controller.create(session);
		session.subscriber = Subscriber.create(session);
		return session;
	}

 

修改SessionManager类里面的createSession方法:

/**
	 * Create new Session (but add later).
	 * edit by czp
	 */
	public Session createSession(Event anEvent) throws PushletException {
		/*
		 * 如果存在user,创建一个带有userid的session,
		 * sessionId变成userid
		 */
		Session session = null;
		if(anEvent.getField("userId") != null && !("").equals(anEvent.getField("userId"))){
			session = Session.create(createSessionId(),anEvent);//个性化方法,加入用户id
		}else{
			session = Session.create(createSessionId());
		}
		return session;
	}

 

这样就可以将sessionId变成有意义的id了,现在前台接收的p_id就是userId了.
