Struts2的配置文件是struts.xml和web.xml

Spring的配置文件是applicationContext.xml和web.xml

Hibernate的配置文件是实体映射配置文件和hibernate.cfg.xml和jdbc.properties

总的流程大致是web层调用Service层，Service层调用DAO层，然后返回

详细流程就是：

1.jsp页面提交表单，通过web.xml里配置的过滤器找到struts.xml里对应的action和方法

2.web层通过applicationContext.xml注入了Service层的对象，从而调用Service层的方法

3.Service层通过applicationContext.xml注入了DAO层的对象，从而调用DAO层的方法

4.DAO层数据库连接的配置在applicationContext.xml中（或hibernate.cfg.xml），连接到数据库后，使用模板执行sql
