'sessionFactory' or 'hibernateTemplate' is required

Question

public class CommonDaoImpl<T> extends HibernateDaoSupport implements ICommonDao<T> {

public void save(T t) {
    this.getHibernateTemplate().save(t);
}

// @Resource(name="sessionFactory")
// public final void setSessionFactoryDi(SessionFactory sessionFactory){
// super.setSessionFactory(sessionFactory);
// }

}
在这里注入sessionFactory是可以的但是我在beans.xml中注入就会报错

<bean id="commonDaoImpl" class="cn.jin.elec.dao.impl.CommonDaoImpl">
    <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>

请大虾们看下到底错在哪里了

完整的错误提示是

该回答引用ChatGPT

根据您提供的错误信息，可以看到错误信息中提到了'sessionFactory' or 'hibernateTemplate' is required，也就是说sessionFactory或者hibernateTemplate是必须的。

---

在您提供的代码中，您已经使用HibernateDaoSupport提供了hibernateTemplate，但是在XML配置中没有指定hibernateTemplate，只指定了sessionFactory，所以导致出现错误。

---

要解决这个问题，您可以在XML配置文件中增加hibernateTemplate的配置，例如：

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<bean id="commonDaoImpl" class="cn.jin.elec.dao.impl.CommonDaoImpl">
    <property name="hibernateTemplate" ref="hibernateTemplate"/>
</bean>

这样就可以通过hibernateTemplate注入sessionFactory，然后在CommonDaoImpl中就可以使用hibernateTemplate来操作数据库了。
