Spring 3 + Hibernate4 事务不成功
本帖最后由 tangtangzizi 于 2013-05-22 23:54:23 编辑 先贴配置吧：

我再整合spring3+Hibernate4，里面的ORM和spring的 bean都是用注解的方式配置的，事务我也想用注解的方式配置，但怎么配置也配置不对，上面就是我配置事务的代码（貌似直接加个@Transactional注解就可以直接写上面的tx:annotation-driven就可以了吧？）。但事实上不行。
其一，我目的是当整个service方法抛出异常了，事务代理自动帮我回滚，但我测试过不行。
其二，我将所有注释的和配置形式的事务代理配置都删掉了，结果我随便一个带修改的操作也成功将数据库修改了（按道理我没配置开启事务的话，是不是不应该自动提交的呢？）。
我已经在配置里显示的写了：<prop key="hibernate.connection.autocommit">false</prop>
貌似hibernate默认就是不开启自动提交的。
另外我附上一段DAO的插入代码：

@Override
public boolean add(T t) {
// TODO Auto-generated method stub
sessionFactory.getCurrentSession().save(t);
return true;
}

spring Hibernate 事务 异常 Java
[解决办法]
另外。
@EnableTransactionManagement and <tx:annotation-driven/> only looks for @Transactional on beans in the same application context they are defined in. This means that, if you put annotation driven configuration in a WebApplicationContext for a DispatcherServlet, it only checks for @Transactional beans in your controllers, and not your services. See Section 17.2, “The DispatcherServlet” for more information.
这是官网的提示。
它查找application context they are defined in 。并且不能定义到DispatcherServlet
所以包扫描必不可少
