问题解决：
找到缓存目录，删除缓存文件，重启tomcat（把tomcat路径下temp文件夹中shiro产生的缓存文件删除，然后重新运行）
我的缓存目录是tomcat/temp文件夹下(见上面代码块中红色的位置)
[*** temp]# ll
-rw-r--r--. 1 root root 1321166 2月 20 17:32 active%0053essions%0043ache.data
-rw-r--r--. 1 root root 2325 2月 20 17:00 sys%0043ache.data
-rw-r--r--. 1 root root 3674 2月 20 17:00 user%0043ache.data
