shiro报错 org.apache.shiro.UnavailableSecurityManagerException

自己照着教程搭springboot+mybatis+shiro前后端分离的一个框架。碰到了问题，几天了，很困惑，烦请知道的朋友给点建议

org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.  This is an invalid application configuration.

网上搜了两圈答案无果。

执行这句话就报错。getSubject();
