Three ways to set the STRUTS2 session expiration date

Method One:
Used anywhere the struts2 frame is used
Servletactioncontext.getrequest (). GetSession (). Setmaxinactiveinterval (XXX);

Method Two:
Defines a HttpServletRequest member object Req in action;
The action class implements the Servletrequestaware interface, which implements the method;
In the implementation of the method written: Req= method parameters;
Then use Req.getsession () anywhere in the action where the session is needed ...

Method Three:
Set the duration of the session in the project's Web. xml
<session-config>
<session-timeout>30</session-timeout>
</session-config>

The session-timeout element is used to specify the default session time-out interval, in minutes. The element value must be an integer. If the value of the session-timeout element is zero or negative, it means that the session will never time out. The value range of the Session-timeout is 1-1440.



Comparison of Setmaxinactiveinterval and Session-config:
1, Setmaxinactiveinterval high priority, if Setmaxinactiveinterval is not set, the default is the time set in Session-config.
2. Setmaxinactiveinterval sets the expiration time of the current session, not the entire Web service.
3, the Setmaxinactiveinterval parameter is the second, Session-config is configured in the Session-timeout is the minute.
