SSM环境搭建
流程
1，maven 依赖
2，spring 配置文件
3，mybatis 配置文件
4，springMVC 配置文件
5，web.xml
pom依赖
1，定义版本
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <spirng.version>4.3.14.RELEASE</spirng.version> <spirngmvc.version>4.3.14.RELEASE</spirngmvc.version> <mybatis.version>3.4.1</mybatis.version> <ms.version>1.3.0</ms.version> <jackson.version>2.9.5</jackson.version> <dbcp.version>1.4</dbcp.version> <mysql.version>5.1.38</mysql.version> <servlet.version>3.0.20100224</servlet.version> </properties>
2，依赖
