maven+SSM框架工程搭建
1.百度下载 maven 和 tomcat 安装 配置环境变量
2.使用最新版eclipse 集成maven
maven conf文件夹下的settings.xml文件配置存放maven仓库的位置，D:\hongzhimei\repository 为存放路径
3.新建工程
项目原型选择webapp项目
在buildPath中选择Edit更改为工作空间默认的jdk，项目目录会变成这样
在程序部署中把test删除，程序就不会编译test的代码
在pom.xml文件中添加依赖,然后等待jar包下载.

目前这里会有个报错，需要配置一下servlet，我这里用的是Tomcat6
这样就不报错了。
4.数据库搭建
我这里就用了mysql，插入了一张很简单的表。
5.整合SSM框架
搭建目录
在resource文件夹下加上这些配置文件
6.运行测试
显示结果
下面是jsp java代码
