错误嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException WebFlow

Question

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) ï¿初始化失败 12:16:46,989 INFO [stdout]（MSC 服务线程 1-7） org.springframework.beans.factory.BeanCreationException：创建名称为“flowExecutor”的bean时出错：设置bean属性“flowExecutionListenerLoader”时无法创建[org.springframework.webflow.config.FlowExecutionListenerLoaderFactoryBean]类型的内部bean“（内部bean）”；嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名称为“(inner 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：创建 ServletContext 资源 [/WEB-INF/spring/transportes-webflow.xml] 中定义的名为“jpaFlowExecutionListener”的 bean 时出错：设置时无法解析对 bean“entityManagerFactory”的引用构造函数参数；嵌套异常为 org.springframework.beans.factory.NoSuchBeanDefinitionException：未定义名为“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

Answer 1

NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' is defined

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

<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 配置导入 (WEB-INF/spring/transportes-webflow.xml< /code>)

<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>
