JavaWeb_(Spring框架)Spring整合Hibernate


  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.Driverproperty>
        <property name="hibernate.connection.url">jdbc:mysql:///springproperty>
        <property name="hibernate.connection.username">rootproperty>
        <property name="hibernate.connecton.password">123456property>
        
        
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialectproperty>
        
        <property name="hibernate.show_sql">trueproperty>
        
        <property name="hibernate.format_sql">trueproperty>
        
        <property name="hibernate.hbm2ddl.auto">updateproperty>
        
        <property name="hibernate.connection.isolation">4property>

hibernate.cfg.xml

  使用Spring框架整合Hibernate后

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


    <bean name="transactionManager"
        class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        
        <property name="sessionFactory" ref="sessionFactory">property>
