1. 在web容器中设置(此处以tomcat为例)
在tomcat-5.0.28\conf\web.xml中设置,以下是tomcat 5.0中的默认配置:
[html] view plaincopyprint?
- <!-- ==================== 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>
<!-- ==================== 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默认session超时时间为30分钟,可以根据需要修改,负数或0为不限制session失效时间。
2. 在工程的web.xml中设置
[html] view plaincopyprint?
- <!-- 时间单位为分钟 -->
<!-- 时间单位为分钟 -->
<session-config>
<session-timeout>15</session-timeout>
</session-config>
3. 通过java代码设置
session.setMaxInactiveInterval(30*60);//以秒为单位
三种方式优先级:1 < 2 <3
