本文详细介绍Struts、Spring和Hibernate（SSH）三大框架的整合步骤，包括环境搭建、配置文件设置及书籍增删改查实例。从数据库建立到前端展示，为读者提供了一个完整的实战案例。
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
