1、导入坐标以及补全包结构

2、web.xml

3、applicationContext.xml

4、springmvc.xml

5、其它配置文件

内容大致包括以下几点

(1)web.xml

spring 监听器ContextLoaderListener

springmvc前端控制器dispatcherServlet

乱码过滤器CharacterEncodingFilter

(2)applicationContext.xml

组件扫描（主要是service和mapper，不扫描controller）

整合mybatis核心配置文件（代替sqlMapConfig.xml）

(3)springmvc.xml

扫描组件主要是controller

配置mvc注解驱动

内部资源视图解析器

开放静态资源访问权限

(4)mybatis核心配置文件sqlMapConfig.xml（这个被整合到了applicationContext.xml中）

别名（typeAliases）

配置环境

加载映射

druid.jdbc.password=root

log4j.properties

#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
