自己照著教程搭springboot+mybatis+shiro前後端分離的一個框架。碰到了問題，幾天了，很困惑，煩請知道的朋友給點建議

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.

網上搜了兩圈答案無果。

執行這句話就報錯。getSubject();
