Mybatis3+Spring4+SpringMVC4 整合

首先在整合这个框架的时候，想想其一般的步骤是怎样的，先有个步骤之后，不至于在后面的搞混了，这样在整合的时候也比较清晰些。

然后我们就细细的一步一步来整合。

1  创建一个Web项目。

    

2  导入Mybatis3、Spring4、SpringMVC4、连接数据库（我使用的数据库是mysql）的jar包。

 我所用的包：


  

 spring-websocket-4.2.0.RELEASE.jar

 

3  创建Mybatis3、Spring4、SpringMVC4、连接数据库的配置文件。

    


 

 

4  配置web.xml
