2019年2月11日 - 注册免费送38元体验金

                             

0.费用流程:

1.类型约定:

   6个小组:

小组项目名称:EasyBuy_flc或者(EasyBuy_01)

小组数据库名称:EasyBuy_flc

版本控制工具:svn,不再使用

前几天可以将自个儿小组的连串上传到git上

 

支出流程控制:     

老板:所有的html页面改成jsp后缀,并且,然后确立数据库和数据表

      A组员:设计数据库,书写数据表中文字段名称

      B组员:设计实体类

开头分层:

工具BaseDao:

package cn.com.dao;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;

public class BaseDAO {
    public static final String driver = "com.mysql.jdbc.Driver";
    public static final String url = "jdbc:mysql://localhost:3306/easybuy?useUnicode=true&charaterEncoding=UTF-8";
    public static final String username = "root";
    public static final String pwd = "1234";
    public Connection con=null;
    public PreparedStatement ps=null;
    public ResultSet rs=null;

    //获取连接getConnection
    public Connection getConnection() throws Exception {
        //加载驱动
        Class.forName(driver);
        if (con == null || con.isClosed()) {
            con = DriverManager.getConnection(url, username, pwd);
        }
        return con;
    }

    //查询 executeQuery
    public ResultSet executeQuery(String sql, Object...objects) throws Exception {
        con = getConnection();
        ps = con.prepareStatement(sql);
        for (int i = 0; i < objects.length; i++) {
            ps.setObject(i + 1, objects[i]);
        }
        rs = ps.executeQuery();
        return rs;
    }

    //增、删、改
    public int executeUpudate(String sql, Object... objects) throws Exception {
        con = getConnection();
        ps = con.prepareStatement(sql);
        for (int i = 0; i < objects.length; i++) {
            ps.setObject(i + 1, objects[i]);
        }
        int num = ps.executeUpdate();

        return num;
    }

    public void closeAll() throws Exception {
        if (rs != null || !rs.isClosed()) {
            rs.close();
        }
        if (ps != null || !ps.isClosed()) {
            ps.close();
        }
        if (con != null || !con.isClosed()) {
            con.close();
        }
    }
}

dao层:

public interface IUserDao {
    //根据用户名和密码查询对象
    public int select(String name,String pwd) throws Exception;
    //查询用户信息返回泛型集合
    public List<User> getAllList() throws Exception;
 
}

dao的落到实处层:

public class UserDaoImpl extends BaseDAO implements IUserDao{
     @override
public int select(String name,String pwd) throws Exception{
    string sql="select count(1) from easybuy_user where loginname=? and loginname=?";
    ResultSet  rs=executeQuery(sql,name);
    if(rs!=null){
         while(rs.next()){
              num=rs.getInt("id"):
      }
}
        return num;
    }
@Override
 public List<User> getAllList() throws Exception {
  List<User> list=new ArrayList<User>();
  String  sql="select * from easybuy_user";
  ResultSet rs = executeQuery(sql);
  if(rs!=null){
   while(rs.next()){
    User users=new User();
    users.setId(rs.getInt("id"));
    users.setLoginName(rs.getString("loginname"));
    users.setUserName(rs.getString("username"));
    users.setPassword(rs.getString("password"));
    users.setIdentityCode(rs.getString("identitycode"));
    users.setSex(rs.getInt("sex"));
    users.setMobile(rs.getString("mobile"));
    users.setType(rs.getInt("type"));
    users.setEmail(rs.getString("email"));
    list.add(users);
   }
  }
  return list;
 }




}

services层:

public interface IUserService {
//根据用户名和密码查询对象
        public int select(String name,String pwd) throws Exception;
//查询用户信息返回泛型集合
    public List<User> getAllList() throws Exception;


}

services实现层:

public class UserServiceImpl implements IUserService{

    UserDaoImpl dao=new UserDaoImpl();
@Override
    public int select(String name, String pwd) throws Exception {

        return dao.select(name, pwd);
    }
@Override
 public List<User> getAllList() throws Exception {
  
  return dao.getAllList();
 }
}

 静态页面:

                <form action="user?title=login" method="post"
                    onsubmit="return checks(this)" id="myform">

MD5加密工具:

public class Md5Tool{
           public String getMD5(String pwd){
          //用于加密的字符
               char md5String[] ={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
          try{
                //使用平台的默认字符集将此String编码为bytex序列,并将结果存储到一个新的byte数组中
               byte[] btInput=pwd.getBytes();
               //信息摘要是安全的单向哈希函数,它接受任意大小的数据,并输出固定长度的哈希值。
               MessageDigest mdInst=MessageDigest.getInstance("MD5");
              //MessageDisgest对象通过使用update方法处理数据,使用指定的byte数组更新摘要
               mdInst.update(btInput);
             //摘要更新之后,通过调用disgest()执行哈希计算,获得密文
               byte[] md = mdInst.digest();
            //把密文转换成十六进制的字符串形式
               int j=md.length;
               char str[] = new char[j*2];
               int k=0;
              for(int i=0;i<j;i++){         //i=0
                   byte byte0=md[i];       //95
                   str[k++] = md5String[byte0>>>4&0xf];    //5
                   str[k++] = md5String[byte0&0xf];    //F
           }

        //返回经过加密后的字符串
            return new String(str);
          }catch(Exception e)
               return null;
}
}
}

验证码问题:

1.为何要在网站中参与验证码?

分析:为了防止机器恶意注册,1s内在大家的数据库中形成N条记录

2.验证码落成机制:

 解析:为了防范浏览器读取缓存中的验证码图片,首先在形成验证码的Servlet处理程序中装置浏览器不缓存,第三种手段就是给请求的Servlet加一个随机数,那样就保险每便都从服务器拿一张验证码图片。说白了验证码就是一个服务器端的后台类(Servlet),以流的不二法门回送到客户端浏览器,用img标签承载。

3.雕虫小技

分析:验证的时候先举办验证码的校验,假如发现验证码不同盟,
就不要再作证用户名和密码,那样就省去了和数据库的三回交互。

验证码工具书写:

package cn.buy.util;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.util.Random;

public class AuthCode {

    public static final int AUTHCODE_LENGTH = 5;        //验证码长度  
    public static final int SINGLECODE_WIDTH = 15;  //单个验证码宽度  
    public static final int SINGLECODE_HEIGHT = 30; //单个验证码高度  
    public static final int SINGLECODE_GAP = 4;     //单个验证码之间间隔  
    public static final int IMG_WIDTH = AUTHCODE_LENGTH * (SINGLECODE_WIDTH + SINGLECODE_GAP);  
    public static final int IMG_HEIGHT = SINGLECODE_HEIGHT;  

    public static String getAuthCode() {  
        String authCode = "";  
        for(int i = 0; i < AUTHCODE_LENGTH; i++) {  
            authCode += (new Random()).nextInt(10);  
        }  
        return authCode;  
    }  

    public static BufferedImage getAuthImg(String authCode) {  
        //设置图片的高、宽、类型  
        //RGB编码:red、green、blue  
        BufferedImage img = new BufferedImage(IMG_WIDTH, IMG_HEIGHT, BufferedImage.TYPE_INT_BGR);  
        //得到图片上的一个画笔  
        Graphics g = img.getGraphics();  
        //设置画笔的颜色,用来做背景色  
        g.setColor(Color.YELLOW);  
        //用画笔来填充一个矩形,矩形的左上角坐标,宽,高  
        g.fillRect(0, 0, IMG_WIDTH, IMG_HEIGHT);  
        //将画笔颜色设置为黑色,用来写字  
        g.setColor(Color.BLACK);  
        //设置字体:宋体、不带格式的、字号  
        g.setFont(new Font("宋体", Font.PLAIN, SINGLECODE_HEIGHT + 5));  

        //输出数字  
        char c;  
        for(int i = 0; i < authCode.toCharArray().length; i++) {  
            //取到对应位置的字符  
            c = authCode.charAt(i);  
            //画出一个字符串:要画的内容,开始的位置,高度  
            g.drawString(c + "", i * (SINGLECODE_WIDTH + SINGLECODE_GAP)+ SINGLECODE_GAP / 2, IMG_HEIGHT);  
        }  
        Random random = new Random();  
        //干扰素  
        for(int i = 0; i < 20; i++) {  
            int x = random.nextInt(IMG_WIDTH);  
            int y = random.nextInt(IMG_HEIGHT);  
            int x2 = random.nextInt(IMG_WIDTH);  
            int y2 = random.nextInt(IMG_HEIGHT);  
            g.drawLine(x, y, x + x2, y + y2);  
        }  
        return img;  
    }  
}

验证码的servlet书写:

public class AuthCodeServlet extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        doPost(request, response);
    }

    public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        String authCode = AuthCode.getAuthCode();  

        request.getSession().setAttribute("authCode", authCode); 
        //将验证码保存到session中,便于以后验证  
        try {  
            //发送图片  
            ImageIO.write(AuthCode.getAuthImg(authCode), "JPEG", response.getOutputStream());  
        } catch (IOException e){  
            e.printStackTrace();  
        } 
    }

}

 商品详情图片的一个拓宽的功力:

前台image图片的代码:

<div id="tsShopContainer">

        </div>
