本文介绍如何正确配置Hibernate的getCurrentSession()方法，并确保在进行数据库查询时启动了事务。主要内容包括设置Hibernate属性和在代码中开始及提交事务。

first of all if you want to use getcurrentSession() method you need to add these properties to HibernateProperties:
<prop key="hibernate.current_session_context_class">thread</prop>
<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>

添加后如下：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.Oracle9Dialect </prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.current_session_context_class">thread</prop> <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop> </props> </property> <property name="mappingResources"> <list> Log.hbm.xml</value> </list> </property> </bean>

second thing is from the exception, Hibernate3 doesn't allow you to run queries without starting a transaction. you have to add this to your init method before running the query:
sessionFactory.getCurrentSession().beginTransactio n();
and of course commit it in the end of your unit of work.
