1. Set up in the web container (tomcat here)
Set in tomcat-5.0.28\conf\web.xml, the following is the default configuration in tomcat 5.0:
<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly -->
<!-- created sessions by modifying the value below. -->
<session-config>
<session-timeout>30</session-timeout>
</session-config>
Tomcat's default session timeout is 30 minutes, which can be modified as needed. Negative Numbers or 0 do not limit session expiration time.
2. Set in the web.xml of the project
<!-- Time is measured in minutes -->
[html] view plaincopy
<session-config>
<session-timeout>15</session-timeout>
</session-config>
3. Set through Java code
session.setMaxInactiveInterval ( 30*60 ) ;//In seconds & NBSP; < br / >
