一.简介

SSM（Spring+SpringMVC+MyBatis）框架集由Spring、SpringMVC、MyBatis三个开源框架整合而成，常作为数据源较简单的web项目的框架。
其中Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架。
SpringMVC分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制。
MyBatis是一个支持普通SQL查询，存储过程和高级映射的优秀持久层框架。

二.开发工具

intellij idea: 15

jdk:1.8

tomcat:7.0.75

mysql: 5.5

maven:3

三.idea创建maven工程

1.新建maven工程

这里写图片描述

选择maven-web工程-下一步
这里写图片描述

填写groupID、artifactId
这里写图片描述
默认选择本地的maven资源-下一步

输入项目名称 web-完成
这里写图片描述

项目结构如图示：

四.配置spring、springmvc、mybatis 等相关依赖
