1、环境搭建
1.1概念
Spring是一个Java应用的开源框架，Bean/Context/Core/IOC/AOP/MVC等是其重要组件，IOC控制反转，AOP面向切面编程，各种注入方式，实现方式不再一一列举；
SpringMVC是一个基于请求的Web框架，模型视图控制器，涉及的控制器解析器处理器以及流程，不再一一列举；
Mybatis是一个基于原型ibatis的Java持久层框架，消除jdbc代码，仅通过简单的配置与映射，通过接口实现与数据库的交互；
1.2环境
JDK：从sun公司官网下载jdk，安装，配置环境变量（新建变量名：JAVA_HOME 变量值：（例如）E:Javajdk1.6.0_43；编辑变量名：Path 在后面加上：%JAVA_HOME%in;%JAVA_HOME%jrein），cmd中输入java -version测试；
Tomcat：从apache官网下载Tomcat，安装，不配置环境变量；
Maven：从Maven官网下载Maven，安装或者解压，配置环境变量（ 新建变量名：MAVEN_HOME 变量值：（例如）D:serverapache-maven-3.2.1；编辑变量名：Path 在最前面加上：%MAVEN_HOME%in;）
eclipse或者idea编辑器；
2、项目创建
idea创建Maven项目
2.1创建项目
groupId为项目组织id或者编码等
artifactID为项目的Id或者编码等
3、配置整合
3.1 Maven引入需要的JAR包
修改pom.xml
