servlet+jdbc+javabean其实跟ssh差不多

我给的这个架构可以代替ssh的架构进行项目的开发

common中放的是一些公用类

dao中放的是一些对数据的处理

entity其实也就是javabean

service中放的是一些抽象类，简单来说抽象类就是有一些接口，所谓的接口就是只有"方法名，加上一个分号".如下

 1 package com.ll.www.mis.service;
 2 
 3 import java.io.IOException;
 4 import java.util.List;
 5 
 6 import javax.servlet.ServletException;
 7 import javax.servlet.http.HttpServletRequest;
 8 import javax.servlet.http.HttpServletResponse;
 9 
10 public interface IOrderService {
11     
12    public void SelectAll(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException;
13      
14    public void SelectByPar(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException;
15    
16    public void Save(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException;
17    
18    public void Update(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException;
19    
20    public void Delete(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException;
21 
22 }
