spring中 shiro logout 配置方式

spring中 shiro logout 配置方式有两种方式实现logout

1. 普通的action中 实现自己的logout方法，取到Subject，然后logout

 @RequestMapping(value = "${adminPath}/logout", method = )
	public String logout(HttpServletRequest request, HttpServletResponse response, Model model) throws IOException {
		Principal principal = ();
		// 如果已经登录，则跳转到管理首页
		if(principal != null){
			().logout();
		}
		return "redirect:" + adminPath+"/login";
	}

这种需要在ShiroFilterFactoryBean 中配置 filterChainDefinitions

对应的action的url为anon

<bean name="shiroFilterChainDefinitions" class="">
		<constructor-arg>
			<value>
				/static/** = anon
				/userfiles/** = anon
				${adminPath}/cas = cas
				${adminPath}/login = authc
				${adminPath}/logout = anno
				${adminPath}/** = user
				/act/rest/service/editor/** = perms[act:model:edit]
				/act/rest/service/model/** = perms[act:model:edit]
				/act/rest/service/** = user
				/ReportServer/** = user
			</value>
		</constructor-arg>
	</bean>

2. 使用shiro提供的logout filter 需要定义 相应的bean

<<bean  class="">
		<property name="securityManager" ref="securityManager" /><!-- 
		<property name="loginUrl" value="${}?service=${}${adminPath}/cas" /> -->
		<property name="loginUrl" value="${adminPath}/login" />
		<property name="successUrl" value="${adminPath}?login" />
		<property name="filters">
            <map>
                <entry key="cas" value-ref="casFilter"/>
                <entry key="authc" value-ref="formAuthenticationFilter"/>
				<entry key="logout" value-ref="logoutFilter" />
            </map>
        </property>
		<property name="filterChainDefinitions">
			<ref bean="shiroFilterChainDefinitions"/>
		</property>
	</bean>

对应在 shiroFilterChainDefinitions中将对应的url改为logout

     <bean name="shiroFilterChainDefinitions" class="">
		<constructor-arg>
			<value>
				/static/** = anon
				/userfiles/** = anon
				${adminPath}/cas = cas
				${adminPath}/login = authc
				${adminPath}/logout = logout
				${adminPath}/** = user
				/act/rest/service/editor/** = perms[act:model:edit]
				/act/rest/service/model/** = perms[act:model:edit]
				/act/rest/service/** = user
				/ReportServer/** = user
			</value>
		</constructor-arg>
	</bean>

并配置loginFilterbean

<bean  class="">
   <property name="redirectUrl" value="${adminPath}/login" />
</bean>
