如何在 Spring Web Flow 中的每个 Dispatcher servlet 之前调用拦截器？

Question

嗨朋友们，我在 Spring Web Flow 中工作，在每个事件之前我想要检查会话是否存在，为此我想要调用拦截器，所以我在此处配置 Web 流中的拦截器时遇到问题，ID 我的 Web 流。

    <!-- Dispatches requests mapped to flows to FlowHandler implementations -->
    <bean class="org.springframework.faces.webflow.JsfFlowHandlerAdapter">
        <property name="flowExecutor" ref="flowExecutor" />
    </bean>

</beans>

<mvc:interceptors /> 旨在与<mvc:annotation-driven /> 一起使用，它不适用于常规配置的HandlerMapping bean。对于那些你需要配置他们的interceptors 属性的人。

要解决您的问题，请删除 <mvc:interceptors /> 并将配置添加到 FlowHandlerMapping bean。

<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
    <property name="order" value="1" />
    <property name="flowRegistry" ref="flowRegistry" />
    <property name="interceptors">
        <bean class="com.pcx.ui.converter.ExecuteTimeInterceptor"/>
    </property>
    <property name="defaultHandler">
        <bean class="org.springframework.web.servlet.mvc.UrlFilenameViewController" />
    </property>
</bean>
