写实现子类的时候最好使用自动的注入方式完成。

Realm用@Component自动注入
<!-- 配置SecuityManager的管理 --> <bean id="securityManager" class="org.apache.shiro.mgt.DefaultSecurityManager"> <!-- 配置你需要使用的Realms --> <property name="realm" ref="memberRealm"></property> </bean>
<!-- shiro里面需要针对于所有的路径进行配置,所有的配置需要通过文本的形式设置 --> <property name="filterChainDefinitionMap"> <value> /*=anon /shiroLogin=anon /messages/**=authc /admin*=authc /pages/welcome.jsp=authc,perms[member:add],perms[dept:add] </value> </property>
<!-- shiro里面需要针对于所有的路径进行配置,所有的配置需要通过文本的形式设置 --> <property name="filterChainDefinitionMap"> <value> /*=anon /shiroLogin.action=anon /messages/**=authc /admin*=authc /pages/welcome.jsp=authc,perms[member:add],perms[dept:add] </value> </property>
不要用filterChainDefinitionMap,要用filterChainDefinitions
