Question

我正在尝试将一些JSF添加到我的Spring WebFlow项目中，并尝试按照以下细节进行一些更改：

http://static.springsource.org/spring-webflow/docs/2.3.x/reference/html/ch13s07.html

但现在我的webflow项目无效。

这是我的旧版flow.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:flow="http://www.springframework.org/schema/webflow-config"
 xmlns:p="http://www.springframework.org/schema/p"

   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />

  <!-- Executes flows: the entry point into the Spring Web Flow system -->
  <flow:flow-executor id="flowExecutor" />

  <!-- The registry of executable flow definitions -->
  <flow:flow-registry id="flowRegistry" 
           flow-builder-services="flowBuilderServices"
           base-path="/WEB-INF/flows">
     <flow:flow-location-pattern value="/**/*-flow.xml" />
  </flow:flow-registry>


 <flow:flow-builder-services id="flowBuilderServices" 
           view-factory-creator="mvcViewFactoryCreator"
           validator="validator"
           /> 


  <bean id="mvcViewFactoryCreator" class=
      "org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
     <property name="defaultViewSuffix" value=".jsp" />   
  </bean>

  <!--Maps request paths to flows in the flowRegistry-->
  <bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
    <property name="flowRegistry" ref="flowRegistry" />
  </bean>

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

</beans>

现在这里是我的新flow.xml文件无效：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:webflow="http://www.springframework.org/schema/webflow-config"
    xmlns:faces="http://www.springframework.org/schema/faces"
    xsi:schemaLocation="

        http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.3.xsd
        http://www.springframework.org/schema/faces
        http://www.springframework.org/schema/faces/spring-faces-2.2.xsd">

    <!-- Executes flows: the central entry point into the Spring Web Flow system -->
    <webflow:flow-executor id="flowExecutor">
        <webflow:flow-execution-listeners>
            <webflow:listener ref="facesContextListener"/>
        </webflow:flow-execution-listeners>
    </webflow:flow-executor>

    <!-- The registry of executable flow definitions -->
    <webflow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices" base-path="/WEB-INF">
        <webflow:flow-location-pattern value="**/*-flow.xml" />
    </webflow:flow-registry>

    <!-- Configures the Spring Web Flow JSF integration -->
    <faces:flow-builder-services id="flowBuilderServices" />

    <!-- A listener maintain one FacesContext instance per Web Flow request. -->
    <bean id="facesContextListener" 
        class="org.springframework.faces.webflow.FlowFacesContextLifecycleListener" />  

</beans>

现在我的faces-config.xml文件：

<?xml version='1.0' encoding='UTF-8'?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0">

    <application>
        <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    </application>

</faces-config>

有人可以告诉我为什么网络流停止工作!!

我认为您正在尝试将faces-config.xml作为Spring配置文件加载。 JSF配置文件（faces-config.xml）是您注册JSF应用程序资源的地方，它不是Spring配置文件，因此不要将其与其他Spring配置文件一起包含。另外/ WEB-INF文件夹是放置faces-config.xml的默认位置。如果你在/ WEB-INF / spring文件夹中有它，那么你需要在web.xml中提到这样的路径：

<context-param>
  <param-name>javax.faces.CONFIG_FILES</param-name>
  <param-value>
   /WEB-INF/faces/faces-config.xml
  </param-value>
</context-param>

与具体问题无关，您还需要在faces-config.xml中使用'SpringBeanFacesELResolver'来解析任何Spring bean，然后再将它们注入任何JSF托管bean。

<faces-config>
  <application>
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
  </application>
<faces-config>

试图将JSF添加到我的Spring WebFlow项目中，现在我的WebFlow将无法正常工作
