尝试为个别操作配置拦截器，如下所示。

<action name="yourAction" class="com.YourActionClass">
    <interceptor-ref name="tokenSession"></interceptor-ref>
    <interceptor-ref name="defaultStack"></interceptor-ref>
    <result name="success">/success.jsp</result>
    <result name="input">/update.jsp</result>
</action>

在我的应用程序中使用令牌拦截器获取异常后
