总体大概目录
主要 配置：pom.xml 配置、web.xml配置、applicationContext.xml配置、springmvc.xml配置
日志log4j2.xml、xxMapper.xml配置；
对三层的MVC搭建：entity层、service层、controller层；
对象和SQL映射mapper层；
1 对pom.xml依赖下载

3、对web.xml进行配置
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"

5、对springmvc.xml进行配置
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
