我正在使用 Hibernate 的延迟加载,并且在将 OpenSessionInViewFilter 添加到我的 web.xml 之后,我开始得到 sessionFactory 丢失异常,即使在定义了要使用的 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)
这似乎是同一个问题,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 移动到名为 root-spring.xml 的文件)我得到了服务器启动的异常。
知道我缺少什么吗?
