## UUID介绍 ##

（1）什么是uuid  
全球唯一的，不会重复的 固定长度的随机字符串  
`25fd9bcf50ad4dc39aa38f084d1801c8`  
（2）复制UUI工具类  
com\\wzx\\util\\UuidUtil.java

public final class UuidUtil { 
    	private UuidUtil(){ }
    	public static String getUuid(){ 
    		return UUID.randomUUID().toString().replace("-","");
    	}
    
    }

（3）测试

public class UuidUtilTest { 
    
        @Test
        public void getUuid() { 
            for (int i = 0; i < 10; i++) { 
                String code  = UuidUtil.getUuid();
                System.out.println(code);
            }
    
        }
    }

# 后台代码 #

## 注册用户设置状态与激活码 ##

user.setStatus("N");//未激活
     user.setCode(UuidUtil.getUuid());//激活

## 激活方法测试 ##

@Test
        public void test04() { 
            UserService userService = new UserService();
            //根据 code -> status 改为Y
           int code = userService.active("bb26f0d05ea745c5986bc18ff7b4cef9");
            System.out.println(code);
        }

## 激活方法实现 ##

public int active(String activeCode) { 
            UserDao userDao = MySessionUtils2.getMapper(UserDao.class);
            int code =  userDao.updateStatus(activeCode); //1 表示成功
            MySessionUtils2.commitAndClose();
            return code;
        }

## UserDao updateStatus 方法实现 ##

//update tab_user set status ='Y' where code = 'bb26f0d05ea745c5986bc18ff7b4cef9';
        int updateStatus(String activeCode);

映射文件修改

<update id="updateStatus" parameterType="string" >
            update tab_user set status ='Y' where code = #{code};
        </update>

编写dao方法的测试

@Test
        public void update() { 
            UserDao dao =    MySessionUtils2.getMapper(UserDao.class);
            int code =  dao.updateStatus("bb26f0d05ea745c5986bc18ff7b4cef9");
            System.out.println(code);
            MySessionUtils2.commitAndClose();
        }

# 前台代码 #

http://localhost:8080/lvyou_war_exploded/activeServlet?activeCode=bb26f0d05ea745c5986bc18ff7b4cef9

## 编写ActiveServlet ##

com\\wzx\\web\\servlet\\ActiveServlet.java

@WebServlet("/activeServlet")
    public class ActiveServlet extends HttpServlet { 
        protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
                doGet(request,response);
        }
    
        protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
            //获取参数 activeCode //lvyou/activeServlet?activeCode=bb26f0d05ea745c5986bc18ff7b4cef9
            String activeCode = request.getParameter("activeCode");
            //处理参数
            UserService userService = new UserService();
            int code = userService.active(activeCode);
            System.out.println(activeCode);
            //响应给浏览器
            String msg = "";
            if(code==1){ 
                msg="激活成功可以使用";
            }else{ 
                msg="激活失败";
            }
            request.setAttribute("msg",msg);
            request.getRequestDispatcher("message.jsp").forward(request,response);
        }
    }

src\\main\\webapp\\message.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
    <html>
    <head>
        <title>Title</title>
    </head>
    <body>
    ${msg}

# 使用邮件发送激活链接 #

*  MailUtil是发送邮件的工具类
 *  直接从资料复制过来
 *  需要编写 个测试

public final class MailUtils { 
        private static final String USER = "289393698@qq.com"; // 发件人称号，同邮箱地址
        private static final String PASSWORD = "aghemvlpcgpubjaa"; // 如果是qq邮箱可以使户端授权码，或者登录密码
    
        /** * * @param to 收件人邮箱 * @param text 邮件正文 * @param title 标题 */
        /* 发送验证信息的邮件 */
        public static boolean sendMail(String to, String text, String title){ 
            try { 
                final Properties props = new Properties();
                props.put("mail.smtp.auth", "true");
                props.put("mail.smtp.host", "smtp.qq.com");
    
                // 发件人的账号
                props.put("mail.user", USER);
                //发件人的密码
                props.put("mail.password", PASSWORD);
    
                // 构建授权信息，用于进行SMTP进行身份验证
                Authenticator authenticator = new Authenticator() { 
                    @Override
                    protected PasswordAuthentication getPasswordAuthentication() { 
                        // 用户名、密码
                        String userName = props.getProperty("mail.user");
                        String password = props.getProperty("mail.password");
                        return new PasswordAuthentication(userName, password);
                    }
                };
                // 使用环境属性和授权信息，创建邮件会话
                Session mailSession = Session.getInstance(props, authenticator);
                // 创建邮件消息
                MimeMessage message = new MimeMessage(mailSession);
                // 设置发件人
                String username = props.getProperty("mail.user");
                InternetAddress form = new InternetAddress(username);
                message.setFrom(form);
    
                // 设置收件人
                InternetAddress toAddress = new InternetAddress(to);
                message.setRecipient(Message.RecipientType.TO, toAddress);
    
                // 设置邮件标题
                message.setSubject(title);
    
                // 设置邮件的内容体
                message.setContent(text, "text/html;charset=UTF-8");
                // 发送邮件
                Transport.send(message);
                return true;
            }catch (Exception e){ 
                e.printStackTrace();
            }
            return false;
        }
    
    
    }

测试代码

public class MailUtilsTest { 
    
        @Test
        public void sendMail() { 
            //参1 收件人
            //参2 内容
            //参3 标题
            MailUtils.sendMail("hadoop101@126.com","<a href='http://localhost:8080/lvyou_war_exploded/activeServlet?activeCode=bb26f0d05ea745c5986bc18ff7b4cef9'>点击激活途牛旅游账户</a>","激活账户");
        }
    }

## 在注册业务方法中添加发邮件 ##

public int register(User user) { 
            UserDao userDao = MySessionUtils2.getMapper(UserDao.class);
            //判断 用户的账号是否存在
            User user2 = userDao.findByUserName(user.getUsername());
            //不存在，调用保存 返回 1
            if(user2 == null){ 
                user.setStatus("N");//未激活
                String activeCode = UuidUtil.getUuid();
                user.setCode(activeCode);//激活
                userDao.save(user);
                MySessionUtils2.commitAndClose();
    
                //参1 收件人
                //参2 内容
                //参3 标题
                MailUtils.sendMail(user.getEmail(),"<a href='http://localhost:8080/lvyou_war_exploded/activeServlet?activeCode="+activeCode+"'>点击激活途牛旅游账户</a>","激活账户");
                return 1;
            }else{ 
                //存在，返回-1
                return -1;
            }
    
        }
