权限分类型：比如说页面菜单展示的权限、访问接口的权限，根据当前登录用户拥有的所有角色的菜单权限 展示所拥有的菜单列表
配置接口类型的权限：用于查询数据以及新增、修改、删除等等按钮请求后台接口路径权限

根据初始化的一些数据可以看出，组长这个角色拥有50001的权限，而测试员的角色的权限ID属于50001，所有当拥有组长角色的用户登录时，前端页面展示该用户可以给其他新用户赋予测试员的角色，而超级管理员角色的用户拥有赋予其他用户 组长和测试员角色的权限

超级管理员拥有所有的权限，所有角色首先要先拥有菜单权限，然后才有某个后台接口的请求权限，比如：组长需要拥有系统管理菜单下的用户管理菜单，并且有该页面上的新增、修改、删除等按钮权限
