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
