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这样的错误：

12：16：46,989 INFO [stdout]（MSC服务主题1-7）2011-09-20 12：16：46,987 [MSC服务主题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。]类型的内部bean'（内部bean）'。 springframework.webflow.config.FlowExecutionListenerLoaderFactoryBean]设置bean属性'flowExecutionListenerLoader';嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为'（内部bean）＃1'的bean时出错：在设置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]中定义创建名为'jpaFlowExecutionListener'的bean时出错：设置时无法解析bean'entalManagerFactory'的引用构造函数参数;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中有这样的Hibernate配置：

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

和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：

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

如果这个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）

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

或者确保在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>
