spring配合hibernate报错：sessionFactory or hibernateTemplate is required

Caused by: java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required
	at org.springframework.orm.hibernate3.support.HibernateDaoSupport.checkDaoConfig(HibernateDaoSupport.java:118)
	at org.springframework.dao.support.DaoSupport.afterPropertiesSet(DaoSupport.java:44)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1469)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1409)

  原因：

我的com.hibernate.dao.impl.UserDAOImpl.java继承了org.springframework.orm.hibernate3.support.HibernateDaoSupport, spring在初始化容器的时候会对这个对象作一个check, 可以看看HibernateDaoSupport源码中的checkDaoConfig()方法

 

 protected final void checkDaoConfig()
 {
   	if (this.hibernateTemplate == null)
        throw new IllegalArgumentException("'sessionFactory' or 'hibernateTemplate' is required");
  }

 

所以，在com.hibernate.dao.impl.UserDAOImpl对象一定要注入一个sessionFactory or hibernateTemplate对

象。

 

<bean id="userDao" class="com.hibernate.dao.impl.UserDAOImpl">
	<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
