spring - 使用 OpenSessionInViewFilter 时出现 No bean named 'sessionFactory' 错误

Question

我正在使用 Hibernate 的延迟加载，在将 OpenSessionInViewFilter 添加到我的 web.xml 之后，我开始出现 sessionFactory 丢失异常，即使在定义要使用的 sessionFactory bean 之后也是如此。

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined
org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:529)
org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1095)
org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:277)
org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197)
org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1097)
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.lookupSessionFactory(OpenSessionInViewFilter.java:242)
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.lookupSessionFactory(OpenSessionInViewFilter.java:227)
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:171)
org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)

This似乎是同样的问题，但不幸的是我不明白解决方案。 我按照建议的解决方案(将 sessionFactory 移动到一个名为 root-spring.xml 的文件)我得到了服务器启动的异常。

知道我错过了什么吗？

尝试将以下配置移动到 applicationContext.xml

    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
          p:location="/WEB-INF/jdbc.properties"/>

    <bean id="dataSource"
          class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
          p:driverClassName="${jdbc.driverClassName}"
          p:url="${jdbc.databaseurl}" p:username="${jdbc.username}"
          p:password="${jdbc.password}"/>


    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation">
