SSH实现的增删改查实例

 学习SSH 2012-05-17
一.整合步骤

1. 通过MyEclipse向导，添加struts功能

2. 通过MyEclipse向导，添加Hibernate3功能：生成会话工厂的那个步骤中一定要将那个对号要去掉，不能由hibernate来生成，而是交给Spring来生成；还有就是导入jar包的时候选择复制到lib目录下这一项。

3. 通过MyEclipse向导，导入实现Spring功能，注意导入jar包的时候选择复制到lib目录下这一项。

3. 利用MyEclipse反向工程的方法，以Spring<dao>生成dao对象的方式创建Hibernate DAO，相关POJO及其xxx.hbm.xml。

4. DAO实现类加入@Transactional标记。

5. 修改applicationContext.xml文件，增加Spring事务管理、DAO等bean的配置。

6. 编写action类。

7. 在applicationContext.xml文件中添加Action的代理bean。

8. 在struts的配置文件中，添加相应的Action，类名指向Spring中的代理bean，并加入<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />和<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="/WEB-INF/classes/applicationContext.xml" />
</plug-in>。

9. 编写Jsp文件。

10. 发布web项目。

11. 启动web服务器，运行项目

二.SSH实现关于书籍增删改查实例

1.创建mysql数据库及其表

create database book;

create table book(id int not null primary key auto_increment,bookname varchar(30),bookauthor varchar(30));

2.表现层
