JavaWeb_(Spring框架)Spring整合Hibernate
2024-09-05 09:11:47
Dao层类要继承HibernateDaoSupport.java父类
原先使用Hibernate框架hibernate.cfg.xml配置数据库
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql:///spring</property>
<property name="hibernate.connection.username">root</property>

applicationContext.xml
在Dao层用到Session session = HibernateUtils.getCurrentSession()；获得session可以修改成
Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();
在Service层用到的关于事务的开启我们可以统一在applicationContext.xml中进行配置
开启事务Transaction beginTransaction = HibernateUtils.getCurrentSession().beginTransaction();
事务回滚beginTransaction.rollback();
提交事务beginTransaction.commit();
在applicationContext.xml中配置事务核心管理器
<!-- 事务的核心管理器 -->
<bean name="transactionManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<!-- 需要sessionFactory -->
<property name="sessionFactory" ref="sessionFactory"></property>
