动态菜单设计

查询当前用户下的菜单权限

思路：根据用户id 左关联表查询出对应的菜单选项

查询SQL

select distinct
    -- 菜单表  去除重复记录
    sys_menu.id,sys_menu.parentId, sys_menu.name
from
-- 权限表
   sys_menu
 
-- 角色与权限表       菜单表id = 角色菜单表的菜单id
left join sys_menu_role ON sys_menu.id = sys_menu_role.mid
 
-- 角色表          角色菜单表的uid = 角色表id
left join sys_role ON sys_menu_role.uid = sys_role.id
 
-- 用户角色表      角色表id = 用户角色表role_id
left join sys_user_role ON sys_role.id = sys_user_role.rid
 
-- 用户表          用户角色表user_id = 用户表的id
left join sys_user ON sys_user_role.uid = sys_user.id
where
    sys_user.id=1;

需要五张表

用户表	sys_user
角色表	sys_role
菜单表(权限表)	sys_menu
用户角色关联表	sys_user_role
角色菜单关联表	sys_menu_role

新建表

中间表进行权限关联 user_role 用户角色表

uid为用户表中的id 其中uid=1 是超级管理员

uid =1 对应的

rid=1 对应的

角色菜单表对应关系 menu_role

sys_menu_role 代表超级管理员对应7个菜单选项

uid=1 表示用户id是1

mid {1,...7} 对应菜单表的

查询结果为 uid=1 对应7个菜单项

当前用户查询下的菜单权限包括父菜单
