2.spring-dao.xml与mybatis-config.xml
主要就是spring整合mybatis
在上面的基础上，去掉成接口的实现类了，需要配置dao接口扫描包，我的理解是这个dao接口扫描包中有datasource，有mapper的扫描范围, 它会自动生成这些接口对应的mapper,并将接口的mapper放到xml文件中，所以在spring-service中，直接
<property name="bookmapper" ref="bookmapper"></property>
引用即可

mybatis-config.xml 详细在上面的mybatis整合spring的文章中，它做两件事，配置映射文件路径，配置接口扫描范围，它被import到 spring-dao.xml中。

3.spring-service.xml
在这个文件中要进行事务的处理（事务本来就应该是在service层），要将service层的类全部放到ioc容器中，然后这些类中因为调用了dao层的类，然后因为刚才第二部配置了接口扫描包，直接ref获取mapper即可

4.引用
将这些文件的引用放到一个大的xml文件中，这个文件只放引用，这样就很容易看

或者在project structure中设置 spring application context，效果是一样的
