Spring MVC+Spring +Hibernate配置事务，但是事务不起作用

最近做项目，被一个问题烦恼了很久。使用Spring MVC+Spring +Hibernate开发项目，在使用注解配置事务管理，刚开始发现无论如何数据库都无法更新，但是可以从数据库查询到数据。怀疑是配置文件的问题，但是反复确认，配置文件没有问题。后来将注解配置事务变更为注解配置事务，同样无法入库。

后来在dao层方法里面添加了session.flush()数据可以入库，但是不能回滚。正常的情况下，配置事务成功的话，事务会自动提交，session会自动flush。于是怀疑配置的事务根本就没有起到作用。在网上查找资料，终于发现问题症结所在。

引起问题原因：spring初始化时优先component-scan bean,注入Web Controller 的Service直接拿了上下文中的@Service("someService"),这个时候@Transactional (readOnly=false, isolation = Isolation.READ_COMMITTED) 还没有被处理.所以Web Controller 的Service是SomeServiceImpl而不是AOP的$ProxyNO.

解决途径：不让spring扫描到ServiceImpl类,直接写在xml文件,其它的配置和annotation照用,这样事务就起作用了.

按照上述配置，发现事务起作用了，自动提交，并且在出现异常的时候自动回滚。

工程具体配置：

InformationDaoImpl.java

后来师父找到了我的问题所在：在springmvc.xml在扫描包的时候缺少了：use-default-filters="false"

 

<context:component-scan base-package="cn.com.yinuo.school" use-default-filters="false" >
        <context:include-filter type="regex" expression="cn.com.yinuo.*.web.*Controller$"/> 
    </context:component-scan>

 

添加之后，去掉spring-core.xml中的

<context:component-scan base-package="cn.com.yinuo.school">
        <context:exclude-filter type="regex" expression="cn.com.yinuo.*.web.*Controller$"/>
        <!-- <context:exclude-filter type="regex" expression=".*ServiceImpl$" /> -->
    </context:component-scan>

以及service的配置执行发现事务同样起到作用了。

去掉我的其他配置，同时不加use-default-filters="false"，会报错 session没有绑定。
