获取到的sessionId 和request 为 null
protected Session retrieveSession(SessionKey sessionKey) throws UnknownSessionException {
Serializable sessionId = getSessionId(sessionKey);
if(sessionId == null) {
System.out.println("sessionId 为 null ");
}
ServletRequest request = null;
if(sessionKey instanceof WebSessionKey) {
request = ((WebSessionKey) sessionKey).getServletRequest();
}
if(request == null) {
System.out.println("request 为 null");
}
if(request != null && sessionId != null) {
Session session = (Session)request.getAttribute(sessionId.toString());
if(session != null) {//在request中取
System.out.println("从request中取...");
return session;
}
}
Session session = super.retrieveSession(sessionKey);//从redis中取
if(request != null && sessionId != null)
request.setAttribute(sessionId.toString(), session);
return session;
}因为sessionId 和request 为 null ，所以也就用不了request 去存取 session 。不知道什么原因？有人帮忙解决一下吗？
