SSM项目开发环境搭建，适合初学SSM的入门人员阅读和使用。
一.环境的准备
1.JDK的安装 2.tomcat安装 3.maven的安装及settings.xml的配置 4.eclipse或者Idea的安装 5.mysql的安装 6.在eclipse中对jdk、tomcat、maven、编码（java和web）的配置
二.进行数据库的设计
1.利用PowerDesigner对数据库进行设计 2.将PD生成的SQL语句导入到数据库中 3.对数据库表进行数据的添加
三.前端页面的简单设计
login.html、index.html.、index.jsp等等
四.创建maven项目引入相关依赖
1.项目名：项目名称_ssm 2.在pom文件中引入相关依赖,项目所需依赖 3.利用节点对jar包版本进行统一管理
