SSH是 struts+spring+hibernate的一个集成框架，是目前比较流行的一种Web应用程序开源框架。
SSH的整合思路
1、导入所需要的pom依赖
2、几大框架的配置文件（web.xml/struts.xml、hibernate的配置、spring的配置）
3、spring与hibernate整合桥接的配置文件替换掉了hibernate.cfg.xml
spring-hibernate.xml(难点)
注册数据库连接信息文件
配置数据库连接池（新的知识点）
配置sessionfactory
配置声明式事务（aop）
com.liuwenwu.base.xxxBiz
com.liuwenwu.book.xxxBiz
com.liuwenwu.book.yyyBiz
com.liuwenwu.*.*Biz
配置Base模块
UserDao
private Session session;
add
session
edit
del
<bean id="sesion" class="....">
<bean id="userDao" class="com.zking.dao.UserDao">
<property name="session' ref="session"></property>
</bean>
4、配置struts.xml
5、做测试
导入所需的pom依赖 不要一次性导入太多，网不好是容易下不全
