springboot整合shiro的时候出现了报错

报错信息：

Description:

No bean of type 'org.apache.shiro.realm.Realm' found.

Action:

Please create bean of type 'Realm' or add a shiro.ini in the root classpath (src/main/resources/shiro.ini) or in the META-INF folder (src/main/resources/META-INF/shiro.ini).

Disconnected from the target VM, address: '127.0.0.1:61129', transport: 'socket'

Process finished with exit code 1

原因：我的配置类和自定义的realm类忘了加相应的注解，没有注入到spring的容器中，因此报错。
解决方法：加上相应注解
