我在 jboss 7.0.1.FINAL 中使用 webflow 2.3.0.RELEASE 和 richfaces 4.0.0.Final 时遇到这样的错误：

12:16:46,989 INFO [stdout]（MSC 服务线程 1-7） 2011-09-20 12:16:46,987 [MSC 服务线程 1-7] 错误（FrameworkServlet.java:314）� 上下文初始化失败 12 ：16：46,989 INFO [stdout]（MSC 服务线程 1-7）org.springframework.beans.factory.BeanCreationException：创建名为“flowExecutor”的 bean 时出错：无法创建 [org. springframework.webflow.config.FlowExecutionListenerLoaderFactoryBean]同时设置bean属性'flowExecutionListenerLoader'；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名称为“（内部 bean）#1”的 bean 时出错：设置 bean 属性“listeners”时无法解析对 bean 'jpaFlowExecutionListener'的引用；嵌套异常是 org.springframework.beans.factory.BeanCreationException：在 ServletContext 资源 [/WEB-INF/spring/transportes-webflow.xml] 中定义名称为“jpaFlowExecutionListener”的 bean 创建错误：设置构造函数参数时无法解析对 bean 'entityManagerFactory' 的引用；嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为“entityManagerFactory”的 bean。

好吧，我想这个错误是因为我在 META-INF 中有 Hibernate 配置，如下所示：

  • META-INF/spring/spring-master.xml
    • META-INF/spring/spring-hibernate.xml
    • META-INF/spring/spring-datasource.xml
    • META-INF/spring/jdbc.properties

以及WEB-INF中的webflow配置：WEB-INF/spring/transportes-webflow.xml

NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' is defined

意味着它无法找到 的 bean 定义entityManagerFactory。从您的 webflow 配置中，它需要jpaFlowExecutionListener：

<bean id="jpaFlowExecutionListener"
  class="org.springframework.webflow.persistence.HibernateFlowExecutionListener">
    <constructor-arg ref="entityManagerFactory"/>
    <constructor-arg ref="transactionManager"/>
</bean>

如果此 bean 定义在：

META-INF/spring/spring-hibernate.xml

它应该由 webflow 配置 ( WEB-INF/spring/transportes-webflow.xml)导入

<import resource="classpath:META-INF/spring/spring-hibernate.xml" />

或者确保您的 Web 配置侦听器中有这两个文件：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:META-INF/spring/spring-hibernate.xml /WEB-INF/spring/transportes-webflow.xml ... </param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
