Spring boot 整合 shiro 出现 org.apache.shiro.UnavailableSecurityManagerException: 错误

<!-- 相当于调用SecurityUtils.setSecurityManager(securityManager) -->
    <bean
        class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">

            value="org.apache.shiro.SecurityUtils.setSecurityManager" />
        <property name="arguments" ref="securityManager" />
    </bean>

　　//主要是这个，但是需要用到 getSecurityManager 所有就贴出来
