解决方法
经过一些列的排查，最终发现，在菜单表中新增的菜单并没有配置该菜单的权限key，即@RequiresPermissions中的关键词。将注解中的key配置在菜单表中后就能解决该问题。这是因为shiro框架中高端doGetAuthorizationInfo方法会将该用户所有的菜单权限key查询出来，并放在框架的缓存后，用来进行判断，该用户是否有相应的权限。
这篇关于Wildcard string cannot be null or empty. Make sure permission strings are properly formatted的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
