125 });

功能接口实现（实现SQL语句的编写和执行，完成人口信息的存储）：

 1 @Override
 2     public boolean add(People people) {
 3         
 4         // TODO Auto-generated method stub
 5         boolean flag=false;
 6         try {
 7             String sql="insert into huseventhpeoplecheck  values('"+people.getTIME()+"','"+people.getHB()+"','"+people.getZFLX()+"','"+people.getXZFMJ()+"','"+people.getXZFJS()+"','"+people.getHZXM()+"','"+people.getSFZHM()+"','"+people.getXB()+"','"+people.getMZ()+"','"+people.getSJYCD()+"')";
 8             PreparedStatement pstmt = conn.prepareStatement(sql);
 9             int i=pstmt.executeUpdate();
10             pstmt.close();
11             conn.close();
12             if(i>0) {
13                 flag=true;
14             }
15         }catch(SQLException e) {
16             System.out.println("人口信息登记失败！！！");
17             e.printStackTrace();
18         }
19         return flag;
20     }

servlet源代码（主要从界面获取所填写的值，并调用接口中的方法，将其存储入数据库中）：

 1 package service;
 2 
 3 import java.io.IOException;
 4 import java.text.SimpleDateFormat;
 5 import java.util.Date;
 6 
 7 import javax.servlet.ServletException;
 8 import javax.servlet.annotation.WebServlet;
 9 import javax.servlet.http.HttpServlet;
10 import javax.servlet.http.HttpServletRequest;
11 import javax.servlet.http.HttpServletResponse;
12 
13 
14 import dao.PeopleDao;
15 import dao.PeopleDaoImpI;
16 import entity.People;
17 
18 /**
19  * Servlet implementation class PeopleAddServlet
20  */
21 @WebServlet("/PeopleAddServlet")
22 public class PeopleAddServlet extends HttpServlet {
23     private static final long serialVersionUID = 1L;
24        
25    
26     /**
27      * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
28      */
29     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
30         request.setCharacterEncoding("utf-8");
31         response.setContentType("text/html;charset=utf-8");
32 
33         SimpleDateFormat formatter= new SimpleDateFormat("yyyy-MM-dd 'at' HH:mm:ss z");
34         Date date = new Date(System.currentTimeMillis());
35         
36         
37         String HB = request.getParameter("HB");
38         String ZFLX = request.getParameter("ZFLX");
39         String  XZFMJ = request.getParameter("XZFMJ");
40         String XZFJS = request.getParameter("XZFJS");
41         String HZXM = request.getParameter("HZXM");
42         String SFZHM = request.getParameter("SFZHM");
43         String XB = request.getParameter("XB");
44         String MZ = request.getParameter("MZ");
45         String SJYCD = request.getParameter("SJYCD");
46         String TIME = formatter.format(date);
47         
48         System.out.println(SFZHM);
49         
50         People p = new People();
51         p.setHB(HB);
52         p.setZFLX(ZFLX);
53         p.setXZFMJ(XZFMJ);
54         p.setXZFJS(XZFJS);
55         p.setHZXM(HZXM);
56         p.setSFZHM(SFZHM);
57         p.setXB(XB);
58         p.setMZ(MZ);
59         p.setSJYCD(SJYCD);
60         p.setTIME(TIME);
61         
62         
63         PeopleDao pd = new PeopleDaoImpI();
64         try {
65             pd.add(p);
66             response.sendRedirect("renkoudengji.jsp");
67             System.out.println("人口添加成功！！！");
68         }catch(Exception e){
69             System.out.println("人口信息添加失败！！！");
70             e.printStackTrace();
71         }
72         
73     }
74 
75 }

该部分主要是人口信息登记方面的功能实现，其最核心的部分就是接口方法的实现，servlet中调用即可。
