使用Idea创建ssm项目，SpringMVC+Spring+MyBatis+Maven整合
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
选择maven-web工程-下一步
填写groupID、artifactId
默认选择本地的maven资源-下一步
输入项目名称 web-完成
项目结构如图示：
四.配置spring、springmvc、mybatis 等相关依赖

五.创建项目目录并标记资源目录
六. 创建相关配置文件并配置web.xml
