Spring MVC之——SSM整合
搭建整合环境
详细信息可以进入以下网址查看
http://www.mybatis.org/spring/
整合说明：SSM整合可以使用多种方式，咱们选择XML + 注解的方式
整合的思路
- 先搭建整合的环境
- 先把Spring的配置搭建完成
- 再使用Spring整合SpringMVC框架
- 最后使用Spring整合MyBatis框架
ps：其实都无所谓啦。。。下面为了看起来不臃肿，代码不重复放出来

log4j配置文件

1、搭建Spring + Mybatis

@SelectKey(statement = {"select last_insert_id()"}, keyColumn = "id", keyProperty = "id", before = false, resultType = Integer.class)
int insertUser(User user);
