Spring集成Hibernate,使用JPA注解方式,新增数据无法提交

环境:

spring 3.1

hibernate 4.2.8 final 

mysql 5.6

问题描述:

调用controller的查询方法,可以正常返回数据

调用controller的创建方法,即:新增数据,控制台打印出了读取和修改序号表的sql,但是没有打印插入数据的sql,数据库表中也没有新增数据。

怀疑是spring控制的事务没有提交,但是排查了两三天,从网上找了各种方法,都没有解决问题。

请各位大侠拉小弟一把,实在是找不到事务为什么没有提交。

说明:

这个扫描组件默认会扫描@Component,@Service,@Repository,@Controller注解,也就是说,你的业务层和持久层的bean被扫描了两次,因为你两个xml文件中都有这个配置。而Controller层的bean要比业务层和持久层的bean晚加载,所以会覆盖它们,而你在控制层中又没有事务配置(也就是dispatcher-servlet.xml文件中没有事务控制),所以可能导致事务不起作用。

如果是上面这个问题,那么:dispatcher-servlet.xml这么配置,只扫描@Controller注解:

<context:component-scan base-package="com.lxl" use-default filters="false">
<context:include-filter type="annotation"      expression="org.springframework.stereotype.Controller" />
</context:component-scan>

applicationController这么配置,不扫描@Controller主键:


/context:component-scan

You config has some issues. You have 2 component-scanS in applicationContext.xml and dispatcher-servlet.xml. Check some material to see what the difference is in these 2 xmlS.

你的jpa没有配置扫描javabean 的路径啊?
