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
