最近封闭开发中,于是近乎一个月都没有更新内容,希望各位看官不要在意。本文我们来介绍Mybatis最入门中的最后一文:与spring的整合。本文仅作为基本Spring+mybatis配置,详细用法及含义需要相关基础知识储配,请各位看官先自行查阅相关资料吧。好了,废话不说,马上开始我们的正文部分吧!
准备工作:
a.操作系统 :win7 x64
b.基本软件:MySQL,Mybatis,SQLyog
注:数据库中的表,数据,请读者按照下文实体建立即可。
-----------------------------------------------------------------------------------------------------------------------------------------------------------1.创建本文我们将使用的工程Mybatis14,工程结构如下:
2.在pom.xml中添加以来,具体内容如下:

除了,这三条配置之外,我们还给出了事物相关的配置供各位看官参考。
关于这些配置发挥作用的时机,有兴趣的读者可以在启动时跟踪代码,观察控制台日志输出来学习,这里不再赘述。
最后,测试方法,在tomcat或其他容器上部署程序运行即可。

至此,Mybatis最入门---整合Spring 结束
备注:
到目前为止,mybatis入门系列的内容就全部结束了,在此,再对开源世界的大神们表示感谢。内容中如果有不妥之处还请积极留言,另外,如果还有想了解内容也可以留言,后续有时间也会更新。
祝好!
