Maven管理,Spring与Mybatis的环境整合

ps.本文旨在提供Spring + Mybatis环境整合的资源文件配置供大家参考.

这里是spring与mybatis的环境整合，使用maven管理
希望对大家有帮助，如有错误或疏漏的地方，请大家指出，在这里先谢谢了.

SSM近来比较受大家喜爱，
但其实有些中小项目呢，用到spring+mybatis也就可以了

ps.这是我一个小课题中使用的jar包与配置文件，可能与大家实际开发项目情况有偏差，请自行判断修改.

1.先是jar包截图 :

2.pom.xml :

pom.xml中jar的版本要注意，这里贴出mvnrepository
http://mvnrepository.com/
若是有版本不兼容等问题，可去mvnrepository中查询指定jar包的其他版本.
