Three ways to set session timeout (fail) in Java

1. Set in the Web container (for example, Tomcat here)

Set in Tomcat-5.0.28\conf\web.xml, the following is the default configuration in Tomcat 5.0:

[HTML]View PlainCopy

2. <!--==================== Default Session Configuration =================--
4. <!--You can set the default session timeout (in minutes) for all newly--
6. <!--created sessions by modifying the value below. -
8. <session-config>
10. <session-timeout>30</session-timeout>
12. </session-config>

Tomcat default session timeout is 30 minutes, can be modified as needed, negative or 0 is not limit session failure time.

2. Set up in the project's Web. xml

[HTML]View PlainCopy

1. <!--time in minutes--

<session-config>

<session-timeout>15</session-timeout>

</session-config>

3. Using Java Code settings

Session.setmaxinactiveinterval (30*60);//in seconds
