SSH简单整合代码

[size=large][size=medium][size=small][size=x-small][size=xx-small]开发环境 ：JDK1.5,Struts1.2,Hibernate3.0,spring1.2
说明：采用MVC模式，引入IOC技术。代码分DAO层，SERVICE层，分别实现DAO层接口，SERVICE接口。在SERVICE层中注入DAO接口。在struts的action里注入SERVICE层接口。使用各层具有相对独立，更好的体现了面向对象思想。DAO的实现可以去extends HibernateDaoSupport 用
getHibernateTemplate()方法操作底层数据库。也可以用这句代码创建一个Session对象
Session session = SessionFactoryUtils.getSession(getSessionFactory(), false);
在用session去操作底层数据库。【完成操作要关闭session释放占用的内存】
