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

14 * transfer 转账的方法
15 * from,to
16 * this.MoneyDao.update(from) from用户的钱减少
17 * this.MoneyDao.update(to) to用户的钱增加
18 * 解释：
19 * 试想一下如果说事物的切面点是切在dao上面，意味着
20 * Transaction t= session.beginTransaction();
21 * this.MoneyDao.update(from)
22 * t.commit();
23 *
24 * Transaction t= session.beginTransaction();
25 * this.MoneyDao.update(to)
26 * t.commit();
27 *
28 * 此时调用MoneyBizImpl.transfer方法
29 * Transaction t= session.beginTransaction();
30 * this.MoneyDao.update(from)
31 * t.commit();
32 *
33 * 此处方法生异常
34 *
35 * Transaction t= session.beginTransaction();
36 * this.MoneyDao.update(to)
37 * t.commit();
38 *
39 * 由上可知：转账涉及到的两个用户不在一个事物中，如果中途发生异常，回滚的话，不能保证数据的唯一性
40 * 切在biz上面：
41 * MoneyAction中调用MoneyBizImpl.transfer方法
42 * Transaction t= session.beginTransaction();
43 * MoneyBizImpl.transfer(from,to);
44 * 相当于this.MoneyDao.update(to)+this.MoneyDao.update(from)
45 * t.commit();
