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

3.利用<properties></properties>节点对jar包版本进行统一管理

五.相关配置文件web.xml、spring.xml、spring_mybatis.xml、springmvc.xml、mybatisconfig.xml

1.web.xml文件

技术分享图片

web.xml文件加载的顺序:

1.全局初始化参数-->2.监听器-->3.过滤器-->4.Servlet

1-->context-param

2.-->listener

3.—>filter

4.-->servlet(springmvc)
