使用 Spring Web 流 + JSF 的流程中不会捕获操作事件

问：

流程正在工作，我可以启动它并访问第一个视图状态激活，但是当我按下它应该触发操作事件以过渡到下一个状态的按钮时，它不起作用。 我尝试了许多解决方案来触发激活.xhtml（成功）中的操作事件，但没有人工作。我想我缺少将JSF与Spring Web Flow集成的配置。

web.xml 包含两个 servlet（Dispatcher + jsf）：

<?xml version="1.0" encoding="UTF-8"?>
<web-app>

    <servlet>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/web-application-config.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    
    <servlet-mapping>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <url-pattern>/spring/*</url-pattern>
    </servlet-mapping>
    
    <!-- Just here so the JSF implementation can initialize, *not* used at runtime -->
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    
    <!-- Just here so the JSF implementation can initialize -->
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.faces</url-pattern>
    </servlet-mapping>

    <!-- Use JSF view templates saved as *.xhtml, for use with Facelets -->
    <context-param>
        <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
        <param-value>.xhtml</param-value>
    </context-param>

</web-app>
