系统逻辑结构

在struts、spring、hibernate三个框架的基础上，分层搭建：

model层：主要存放数据库中的表反转后的java及xml文件

DAO 层：存放对各表中数据的操作，是一个接口层

DAOImpl层：对DAO中方法的实现

service 层：业务逻辑层

serviceImpl层：对service层方法的实现

action层：控制页面跳转

JSP层:主要是页面的设计 直接接触用户的层-System logical structure in the struts, spring, hibernate on the basis of the three frameworks, hierarchical structures: model level: the main storage of the database table after reverse java and xml file DAO layer: the data stored on the operating table is an interface layer DAOImpl layer: the method of implementation of DAO service layers: business logic serviceImpl layer: the implementation of the service layer method of action layer: control page Jump JSP layer: The main page design is the direct contact with the user' s level
