SSH整合

SSH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）
               配置Base模块
4、配置struts.xml
5、做测试

　　导入pom依赖:

 *  为什么一定要切在biz对应的接口上

 *   transfer 转账的方法
 *   from ,to
 *   this.MoneyDao.update(from) from用户的钱减少  
 *   this.MoneyDao.update(to)   to用户的钱增加
 *   
 *   解释：
 *   试想一下如果是事务的切面点是在dao上面，意味着
 *   Transaction t= session.beginTransaction();
 *   this.MoneyDao.update(from)
 *   t.commit();
 *   
 *   Transaction t= session.beginTransaction();
 *   this.MoneyDao.update(to)
 *   t.commit();
 *   
 *   此次调用MoneyBizImpl.transfer方法
 *     Transaction t= session.beginTransaction();
 *   this.MoneyDao.update(from)
 *   t.commit();
 *   此处发生异常
 *   Transaction t= session.beginTransaction();
 *   this.MoneyDao.update(to)
 *   t.commit();
 *   
 *   由上可知：转账涩级到两个不同用户不在一个事务中，如果中途发生异常，回滚的话不会保证数据的唯一性
 *  切在biz上面：
 *  此次调用MoneyBizImpl.transfer方法
 *  
 *  Transaction t= session.beginTransaction();
 *   this.MoneyDao.update(from,to)
 *   t.commit();
