验证码问题：

1.为什么要在网站中加入验证码？

解析：为了防止机器恶意注册，1s内在我们的数据库中形成N条记录

2.验证码实现机制：

 解析：为了防止浏览器读取缓存中的验证码图片，首先在形成验证码的Servlet处理程序中设置浏览器不缓存，第二种手段就是给请求的Servlet加一个随机数，这样就保证每次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)，以流的方式回送到客户端浏览器，用img标签承载。

3.雕虫小技

解析：验证的时候先进行验证码的校验，如果发现验证码不匹配， 就不用再验证用户名和密码，这样就省去了和数据库的一次交互。

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 

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();  
        } 
    }

}

验证码的Ajax，，登录的效验，，鼠标悬停和离开：

前台页面显示js:

1.光标的显示和离开

2.验证码的显示

        String mm=(String)request.getSession().getAttribute("authCode");
