org.apache.shiro.realm.AuthorizingRealm - No cache or cacheManager properties have been set. Authorization cache cannot be obtained.

項目中用spring shiro來處理權限的問題，但是啟動的時候會打印如下日志

org.apache.shiro.realm.AuthorizingRealm  - No cache or cacheManager properties have been set.  Authorization cache cannot be obtained.

檢查了basicRelam配置如下

<bean id="basicRealm" class="com.ebon.platform.realm.BasicRealm" />

BasicRealm繼承自AuthorizingRealm

根據提示信息可以判斷未給BasicRealm指定cacheManager，所以修改如下

<bean id="basicRealm" class="com.ebon.platform.realm.BasicRealm" >
        <property name="authorizationCacheName" value="shiro-authorizationCache"/>
        <property name="cacheManager" ref="shiroCacheManager"/>
</bean>
