在这里插入图片描述
这个相当于前面的myraim的规则

验证一:测试用户是否登录

用户数据库表
在这里插入图片描述
未登录状态访问passUser
在这里插入图片描述
admin/zs登录:(需要盐加密)
在这里插入图片描述

验证二:测试角色授权是否成功

OR 取并集,AND取交集

在这里插入图片描述
1,4分别是zs和zdm
在这里插入图片描述

只有zdm登录能访问passRole
在这里插入图片描述
zs登录
在这里插入图片描述
把Controller层的OR改成And
在这里插入图片描述
用用户角色中间表举例:
预测结果

     用户4 -zdm-才能访问passRole


     用户1--zs-不能访问passRole

在这里插入图片描述

验证三:角色权限

在这里插入图片描述
涉及的数据库表
在这里插入图片描述
在这里插入图片描述
在这里插入图片描述
预测
拥有角色为2,3,4的用户都能访问passPer
在这里插入图片描述
但是这里需要shiro盐加密所以是
在这里插入图片描述
zs,zdm都能访问但是admin不能登录
