Shiro用ehcache缓存session,关于JSESSIONID失效报错问题

15:59:12.430 [http-nio-8080-exec-19] DEBUG o.a.shiro.mgt.DefaultSecurityManager - Resolved SubjectContext context session is invalid.

解决方法如下：

<bean id="sessionManager" class="org.apache.shiro.web.session.mgt.DefaultWebSessionManager">        <property name="sessionDAO" ref="sessionDAO"/>        <property name="sessionIdCookieEnabled" value="true"/>        <property name="sessionIdCookie" ref="sessionIdCookie"/>    </bean>    <!-- 指定本系统SESSIONID, 默认为: JSESSIONID 问题: 与SERVLET容器名冲突, 如JETTY, TOMCAT 等默认JSESSIONID,        当跳出SHIRO SERVLET时如ERROR-PAGE容器会为JSESSIONID重新分配值导致登录会话丢失! -->    <bean id="sessionIdCookie" class="org.apache.shiro.web.servlet.SimpleCookie">        <constructor-arg name="name" value="ycyintang.session.id"/>    </bean>

就是自定义一个不与容器冲突的SEESIONID
