struts2通过拦截器后配置文件如何获取参数值

<result name="login" type="redirectAction">back/login/login_show?areaid=${areaid}</result><interceptor-ref name="defaultStack"></interceptor-ref> <interceptor-ref name="backAuthorizationStack"></interceptor-ref>

${areaid}部分获取action中的参数值,

<interceptor-ref name="defaultStack"></interceptor-ref>

<interceptor-ref name="backAuthorizationStack"></interceptor-ref>

顺序必须先defaultStack否则不好用！
