如何在Spring Web流中的每個Dispatcher Servlet之前調用攔截器？

Question

嗨，朋友們，我正在春季Web流程中工作，在我想要檢查會話的每個事件存在或不存在之前，我都希望調用攔截器，因此我在配置Web流程中的ID的Web流程時遇到問題。

Answer 1

<mvc:interceptors />應該與<mvc:annotation-driven /> ，不適用於常規配置的HandlerMapping Bean。 對於那些，您需要配置其interceptors屬性。

要解決您的問題，請除去<mvc:interceptors />並將配置添加到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>
