SSH项目整合
1.SSH框架结构
action,biz,dao之间的依赖关系由spring维护，动态注入
sping以AOP（面向切面的方式）实现了事务管理器。
spring整合Hibernate时，spring替代实现HibernateSessionFacctory和dao
spring整合struts时，代替实现Action
开发过程中的所有对象由spring控制管理

步骤如下：
1、设计数据库。
2、新建一个web项目。
3、导入项目开发所需的 struts2、spring、hibernate的jar包，
4、使用MiddleGenIDE工具或Myeclipse附带的Add Hibernate Cpabilities功能生成映射文件和映射类。
5、编写applicationContext.xml配置文件。（放在src根目录下）
6、编写struts.xml配置文件。（放在src根目录下）
7、编写web.xml配置文件。（放在WEB-INF根目录下）
8、编写DAO层的代码，每个映射类即实体类都对应一个DAO层，其命名为 “实体类名DAO.java”，如Person.java对应 personDAO.java，它跟映射文件和实体类放在同一个包下。（放在com.xxx.entity包下）
9、编写applicationContext-service.xml配置文件。（放在src根目录下）
10、编写service层的代码，每个DAO层文件对应一个service层文件，即“实体类名DAO.java” - “实体类名 Service.java
11、编写applicationContext-action.xml配置文件。（放在src根目录下）
12、编写action层的代码，action的数量和命名等根据前端显示层的需要来确定。（放在com.xxx.action包下）
13、编写action对应的xxx.xml配置文件，并把它们都用<include file="xxx.xml"></include>添加到 struts.xml文件中。（放在src根目录下）

步骤如下：
1、设计数据库。
2、新建一个web项目。
3、导入项目开发所需的 struts2、spring、hibernate的jar包，
4、使用MiddleGenIDE工具或Myeclipse附带的Add Hibernate Cpabilities功能生成映射文件和映射类。
5、编写applicationContext.xml配置文件。（放在src根目录下）
6、编写struts.xml配置文件。（放在src根目录下）
7、编写web.xml配置文件。（放在WEB-INF根目录下）
8、编写DAO层的代码，每个映射类即实体类都对应一个DAO层，其命名为 “实体类名DAO.java”，如Person.java对应 personDAO.java，它跟映射文件和实体类放在同一个包下。（放在com.xxx.entity包下）
9、编写applicationContext-service.xml配置文件。（放在src根目录下）
10、编写service层的代码，每个DAO层文件对应一个service层文件，即“实体类名DAO.java” - “实体类名 Service.java
11、编写applicationContext-action.xml配置文件。（放在src根目录下）
12、编写action层的代码，action的数量和命名等根据前端显示层的需要来确定。（放在com.xxx.action包下）
13、编写action对应的xxx.xml配置文件，并把它们都用<include file="xxx.xml"></include>添加到 struts.xml文件中。（放在src根目录下）
