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
