[踩坑]使用shiro-redis插件退出登录报缺少id的错

在使用shiro-redis的时候报了这个错误：

org.crazycake.shiro.exception.PrincipalInstanceException: class com.baskbull.library_system.shiro.vo.AccountProfile must has getter for field: id
We need a field to identify this Cache Object in Redis. So you need to defined an id field which you can get unique id to identify this principal. For example, if you use UserInfo as Principal class, the id field maybe userId, userName, email, etc. For example, getUserId(), getUserName(), getEmail(), etc.
Default value is "id", that means your principal object has a method called "getId()"

报这个错误的原因是我的用户名使用的不是id导致的，查阅作者的文档：
shiro-redis使用文档
可以看到我们需要配置
cacheManager.principalIdFieldName = 你设置的id
在网上查到的方法都不管用 我自己找了个地方设置 可以把principalIdFiledName设置在这里：

然后在退出的时候就不会报错啦！
