Spring整合Shiro出现There is no session with id [XXX] with root cause问题的解决方案
最近使用spring + shiro整合的时候出现一个非常头疼的问题，就是会经常出现There is no session with id [XXX]的问题，而且非常难调试出问题的所在，源码也看了关于shiro的部分，但是原因还是找不到。废话不多说，直接上配置文件shiro.xml
/index.do = anon
/agencyLogin.do = anon
/login.do = anon
/user/doLogin.do = anon
/webSocketServer.ws = authc
/user/index.do = kickout,authc,perms[gljgsy_cx]
/user/agencyIndex.do = kickout,authc,perms[jyjgsy_cx]
/user/alertInfo/** = kickout,authc,perms[jkyjrz]
/user/business/** = kickout,authc,perms[ywbl]
/user/inspect/** = kickout,authc,perms[jyxxgl]
/user/vehicle/** = kickout,authc,perms[clxxgl]
/user/agencyManage/** = kickout,authc,perms[jyjggl]
/user/statistics/** = kickout,authc,perms[tjbb]
/user/userManage/** = kickout,authc,perms[yhgl]
/user/log/** = kickout,authc,perms[rzgl]
/user/system/** = kickout,authc,perms[xtsz]
服务器出现异常，具体如下：
严重: Servlet.service() for servlet [spring-action] in context with path [/mtjg] threw exception [org.apache.shiro.session.UnknownSessionException: There is no session with id [04a5e4e8-e5fb-4cd4-99b1-4b2bc792cf29]] with root cause
