该项目是在 Spring 3、Spring web flow 2.3、Spring security 3 和 Primefaces 3.2 中开发的。当我使用 JSF2 的调度程序 servlet 时，视图会完美地使用 AJAX 重新加载，我可以使用标签 h:link。但由于我使用 SWF 的调度程序 servlet，我在上述两种情况下开始遇到问题。

例如，当我使用h:link标记及其属性output="listActivities，结果是href="WEB-INF/views/WEB-INF/views/listActivities.xhtml"。我可以使用h:outputlink解决这个问题标记，因为结果是 href="listActivities" 并且我已将 SWF 配置为使用 UrlBasedViewResolver。

在使用 AJAX 的情况下，应用程序无法正常工作并且消息是 serverError: class com.sun.faces.context.FacesFileNotFoundException /WEB-INF/views/WEB-INF /views/comunes/registro.xhtml Not Found in ExternalContext 作为资源。与使用 h:link 相同的问题。

       distrito" value="#{registro.idDistrito}" title="Seleccione su distrito">

     <f:selectItem itemLabel="Seleccione distrito" itemValue="0"
              noSelectionOption="true"></f:selectItem>
    <f:selectItems var="distrito" value="#{registro.distritos}" itemLabel="#
          {distrito.nombre}" itemValue="#{distrito.idDistrito}">
    </f:selectItems>

    <f:ajax update="barrio calle messageDistrito" render="barrio calle messageDistrito" 
          listener="#{registro.updateBarrio}" event="blur" />

    <f:validateBean for="idDistrito" />
    </h:selectOneMenu>

      <h:message id="messageDistrito" for="distrito" styleClass="messageError" />           

    <h:outputLabel for="barrio" value="Barrio" styleClass="labelInput" />
    <h:selectOneMenu id="barrio" effect="fade" required="true" requiredMessage="Debe
     seleccionar un barrio" value="#{registro.idBarrio}" title="Seleccione su barrio ">

  <f:selectItem itemLabel="Seleccione barrio" itemValue="0" noSelectionOption="true" />     

<f:selectItems var="barrio" value="#{registro.barrios}" itemLabel="#{barrio.nombre}"
               itemValue="#{barrio.idBarrio}">
</f:selectItems>

<f:ajax render="calle messageBarrio" listener="#{registro.updateCalle}" 
         event="valueChange" />
<f:validateBean for="idBarrio" />
</h:selectOneMenu>
<h:message id="messageBarrio" for="barrio" styleClass="messageError" />

检测到的问题是：当我具体在 URL /spring/.....

1- f:ajax 标签不调用侦听器属性中的方法，但“重新加载”视图和第二点发生。

2- 在 URL /WEB-INF/views/WEB-INF/views/中重复上下文路径，当我使用 h:link 标记或更改 ah:selectOneMenu 中的值时会发生这种情况。

3- h:comammdbuton 不起作用，侦听器属性不调用该方法。

当我在 URL /faces/......中使用时，上述步骤工作正常。

为什么会出现这种行为？

亲切的问候。

我认为，您必须在流程中修改您的视图。在示例中：

<view-state id="idView" view="remove your prefix /WEB-INF/view/ so only the folder under that prefix">

faceletsViewResolver 中的前缀必须设置为

<property name="prefix" value="/WEB-INF/" />

并且您的 *.xhtml 文件应该与您的流程定义进入同一文件夹
