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
