我来自LazyInitializationException with hibernate and spring mvc,但现在问题是这个错误:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'sessionFactory' is defined
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:660)

我的web.xml
是:

在我的servlet-context.xml
中,Session Factory的定义如下:
...
<!-- Hibernate session factory -->
<beans:bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<beans:property name="dataSource" ref="dataSource"/>
<!-- Annotated hibernate clasess -->
<beans:property name="packagesToScan" value="org.example.myproject.domains"/>
<beans:property name="hibernateProperties">
<beans:props>
<beans:prop key="hibernate.connection.pool_size">${hibernate.pool_size}</beans:prop>
<beans:prop key="hibernate.dialect">${hibernate.dialect}</beans:prop>
<beans:prop key="hibernate.cache.provider_class">${hibernate.provider_class}</beans:prop>
<beans:prop key="hibernate.show_sql">${hibernate.show_sql}</beans:prop>
<beans:prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl}</beans:prop>
</beans:props>
</beans:property>
</beans:bean>
...
为什么这是hapening?好像我有一个错误的*.xml
定义,你能帮帮我吗?
答案 0 :(得分:0)
您不必删除root-context.xml
,因为您必须将所有bean放在一起分享,并将可见设为web.xml
, servlet-context.xml
以及您拥有的hibernateFilter
,因为现在他“没有看到任何sessionFactory
bean。请查看相关帖子:Spring, Hibernate Lazy Loading, sessionFactory, and OpenSessionInViewFilter。
