前面一节spring与hibernate整合中，事务配置并不完整，运行起来后虽然能在表中加入数据，但其实并拦截到事务
System.out.println(session.getTransaction().isActive());
public void save(User user){ System.out.println("执行UserDao save方法:"); //getCurrentSession方法与openSession方法区别 Session session = sessionFactory.getOppenSession(); //打印事务是否存在 System.out.println(session.getTransaction().isActive()); session.save(user); session.close(); System.out.println("执行UserDao save方法完成"); } 打印事务是否被激活：false １.Service层配置修改
原版配置
这样拿到的userService不具备事务功能
需要再进行配置：
transactionBean是spring_annotation-hibernate.xml中配置的抽象类TransactionProxyFactoryBean
这样配置的意思就是userService = userServiceBase继承自transactionBean，让UserServiceBean的实例具有事务功能
修改后加入一个包：aopalliance-1.0.jar，再行测试：还是没有事务加入
２.再将session = sessionFactory.openSession改为 session = sessionFactory.getCurrentSession();
这时候抛出一个异常：
save is not valid without active transaction
上网查找问题：
需要去掉这行：<prop key="hibernate.current_session_context_class">thread</prop>
测试成功
表明openSession取得的session并没有被事务拦截．
３.主键生成策略改为TABLE方式，抛出异常：
@GeneratedValue(strategy=GenerationType.TABLE, generator="seq") @TableGenerator(name="seq",table="seq_table1",pkColumnName="SEG_NAME",valueColumnName="id",allocationSize = 1,initialValue=10)

修改：
public void save(User user){ System.out.println("执行UserDao save方法:"); //getCurrentSession方法与openSession方法区别 Session session = sessionFactory.getCurrentSession(); //打印事务是否存在 System.out.println(session.getTransaction().isActive()); session.save(user); System.out.println("执行UserDao save方法完成"); } 终于成功了，没有问题． 转载地址：http://wnihj.baihongyu.com/
