1. 框架整合原理：
struts2整合Spring 两种：
一种struts2自己创建Action，自动装配Service ；
一种 将Action交给Spring管理，通过Bean依赖，注入Service
**** 引入jar包，改写Struts2 默认对象工厂, 默认StrutsObjectFactory 改为 StrutsSpringObjectFactory
spring整合hibernate， 将sessionFactory 由Spring管理，将SessionFactory 注入HibernateTemplate , DAO通过HibernateTemplate 操作Hibernate 。
2. 导入jar包（struts2、spring、hibernate框架需要的包及详细说明）
通过这个过程，了解SSH框架所需要的jar包，以及它们的各自用途。下面是我引入的最小jar包的列表：
Struts2 9个
1.struts2-core-2.2.3.jar struts的核心jar包。
2.freemarker-2.3.16.jar Freemarker是struts2默认的模版语言
3.commons-logging-1.1.1.jar Apache Commons包中的一个，包含了日志功能，必须使用的jar包
4.ognl-3.0.1.jar Struts2默认的表达式语言OGNL:对象图形化导航语言
5.xwork-core-2.2.3.jar Struts2核心包，毕竟struts2很大部分是来webwork6.commons-io-2.0.1.jar 封装了一些输入输出流的常用操作
7.commons-fileupload-1.2.2.jar 用来实现文件上传
8. struts2-json-plugin-2.2.3.jar JSON 插件提供了一个 "json" 结果类型来把 action 序列化成 JSON
9. struts2-spring-plugin-2.1.6.jar 使struts2能集成到spring中
Spring框架 13个
1.org.springframework.aop.jar 包含在应用中使用Spring的AOP特性时所需的类
2. org.springframework.beans.jar 所有应用都要用到的，它包含访问配置文件、创建和管理bean以及进行Inversion of Control / Dependency Injection（IoC/DI）操作相关的所有类。
3.org.springframework.context.support.jar 包含支持缓存Cache（ehcache）、JCA、JMX、邮件服务（Java Mail、COS Mail）、任务计划Scheduling（Timer、Quartz）方面的类。
4.org.springframework.context.jar 为Spring核心提供了大量扩展。可以找到使用Spring ApplicationContext特性时所需的全部类，JDNI所需的全部类，UI方面的用来与模板（Templating）引擎如 Velocity、FreeMarker、 JasperReports集成的类，以及校验Validation方面的相关类。
5.org.springframework.core.jar 包含Spring框架基本的核心工具类，Spring其它组件要都要使用到这个包里的类，是其它组件的基本核心。
6.org.springframework.expression.jar Spring表达式语言
7.org.springframework.jdbc.jar 包含对Spring对JDBC数据访问进行封装的所有类。
8.org.springframework.jms.jar 提供了对JMS 1.0.2/1.1的支持类。
9. org.springframework.orm.jar 包含Spring对DAO特性集进行了扩展，使其支持 iBATIS、JDO、OJB、TopLink，因为Hibernate已经独立成包了，现在不包含在这个包里了。这个jar文件里大部分的类都要依赖spring-dao.jar里的类，用这个包时你需要同时包含spring-dao.jar包。
10.org.springframework.transaction.jar 为JDBC、Hibernate、JDO、JPA等提供的一致的声明式和编程式事务管理。
11.org.springframework.web.struts.jar Struts框架支持，可以更方便更容易的集成Struts框架。
12.org.springframework.web.jar 包含Web应用开发时，用到Spring框架时所需的核心类，包括自动载入WebApplicationContext特性的类、Struts与JSF集成类、文件上传的支持类、Filter类和大量工具辅助类。
13. org.springframework.asm.jar Spring独立的asm程序, Spring2.5.6的时候需要asmJar 包,3.0开始提供他自己独立的asmJar
Hibernate3框架10个
1.hibernate3.jar 这个是hibernate3.0的核心jar包，必须的，没的选，像我们常用的Session,Query,Transaction都位于这个jar文件中，必要。
2.cglib-2.1.3.jar CGLIB库，Hibernate用它来实现PO字节码的动态生成，非常核心的库，必要。
3.asm.jar ASM字节码库 如果使用“cglib”则必要，必要
4.asm-attrs.jar ASM字节码库 如果使用“cglib”则必要，必要
5.ehcache.jar EHCache缓存 如果没有其它缓存，则必要，必要
6.antlr.jar 语言转换工,Hibernate利用它实现 HQL 到 SQL。 ANother Tool for Language Recognition是一个工具，必要
7.jta.jar JTA规范，当Hibernate使用JTA的时候需要，不过AppServer都会带上，所以也是多余的。但是为了测试方便建议还是带上。必要
8.commons-collections.jar ApacheCommons包中的一个，包含了一些Apache开发的集合类，功能比java.util.*强大。必要
9.dom4j 是一个Java的XMLAPI，类似于jdom，用来读写XML文件的。Hibernate用它来读写配置文件。必要
10.C3P0.jar C3P0数据库连接池提供数据库连接池
其他4个
1. com.springsource.javax.mail-1.4.0.jar Java email组建，提供email的常用方法
2. mysql-connector-java-5.0.8-bin.jar mysql数据库驱动
3. commons-lang-2.3.jar Apache Commons包中的一个，包含了一些数据类型工具类，是java.lang.*的扩展。必须使用的jar包http://commons.apache.org/lang/
4. log4j-1.2.15.jar 提供日志功能http://logging.apache.org/log4j/
单元测试和其他
junit-4.10.jar
xercesImpl-2.8.1.jar ---这里用到Base64编码(可以不引入)
3. 创建web项目与包结构：
4. 配置SSH开发框架
一般Java都是三层架构 数据访问层（dao） 业务逻辑层（biz 或者services） 界面层（ui）
action 是业务层的一部分，是一个管理器 （总开关）（作用是取掉转）（取出前台界面的数据，调用biz方法，转发到下一个action或者页面） 模型成（model）一般是实体对象(把现实的的事物变成java中的对象)作用是一暂时存储数据方便持久化（存入数据库或者写入文件）而是 作为一个包裹封装一些数据来在不同的层以及各种java对象中使用 dao是数据访问层 就是用来访问数据库实现数据的持久化（把内存中的数据永久保存到硬盘中）
Dao主要做数据库的交互工作
Modle 是模型 存放你的实体类
Service 做相应的业务逻辑处理
Action是一个控制器
