spring+struts2+hbeinate时 我写了:
basedao代码如下
public class BaseDao extends HibernateDaoSupport{
public Session getSess(){
Session session=this.getHibernateTemplate().getSessionFactory().openSession();
return session;
}
不管点出来的是什么getCurrentSession() 都返回了session。
hibernate.cfg.xml配置
<property name="current_session_context_class">thread</property>
applicationContext.xml配置
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation"
value="classpath:hibernate.cfg.xml">
</property>
</bean>
<bean id="baseDao" class="com.qygl.dao.BaseDao">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
请问高手到底怎么能获取到session 。帮我写全些!环境里无异常,提交了有异常,一看12行就是获取session为空,这行Session session=this.getHibernateTemplate().getSessionFactory().openSession();
异常如下:500

basedao代码如下
