Struts+Spring+Hibernate真正入门级实例

网上有很多关于SSH架构的实例文章，但都显得复杂，我想，入门的朋友，还是希望从最简单的CRUD操作开始，一些复杂的数据库关系，逻辑关系，以后在项 目中就能碰到，所以，本文定位于从零开始的一个SSH架构的例子，功能很简单，就是完成一个人员的CRUD操作，麻雀虽小，五脏俱全，希望能对从来没有接 触过三者结合开发的朋友带来一点点帮助，这个例子，也算是我的入门实例，从此，开始Struts+Spring+Hibernate之旅

开发工具：MyEclipse5.1+Tomcat+Mysql

开发前准备：数据库安装，tomcat安装，下载jar包这些就不费口水了，直接切入正题吧
CREATE TABLE `people` (
`id` int(11) NOT NULL auto_increment,
`name` varchar(100) default NULL,
`location` varchar(100) default NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=gb2312 ROW_FORMAT=COMPRESSED;

首先，建立工程和package,以下是我的工程目录
action
DeletePeopleAction.java //删除人员action
EditPeopleAction.java //编辑人员action第一步，读取需要修改的人员资料
EditPeopleActionDo.java//修改人员action
ListPeopleAction.javaSave //显示人员列表action
SavePeopleAction.java //新增人员action
SearchPeopleAction.java //查找人员action
dao
IDAO.java //数据库操作接口
StudentDAOImpl.java//数据库操作实现
domain
AbstractPeople.java //实体抽象类
People.hbm.xml //数据库映射
People.java //实体类
service
IService.java //服务层接口
StudentManagerImpl.java //服务层实现
util
Character.java //字符编码过滤器
PageSupport.java //分页
applicationContext_hibernate.xml //Spring配置文件（hibernate部分）
applicationContext_service.xml //Spring配置文件(Service部分)

JSP：这几个jsp从名字就能看出功能，不说了
addStudent.jsp
editStudent.jsp
searchList.jsp
searchStudent.jsp
studentList.jsp
