目录

一、注册邮件开启授权码

二、用户激活邮箱实现

三、邮箱激活-后端功能实现

修改MailUtils

修改UserServiceImpl

修改UserDao

修改UserService

UserDaoImpl

ActiveUserServlet

四、测试

五、注册失败，遇到的bug

一、注册邮件开启授权码

163邮箱的授权码

需要开通

二、用户激活邮箱实现

邮箱激活流程:

三、邮箱激活-后端功能实现

修改MailUtils

需要修改三处地方，

邮箱地址，邮箱密码或者授权码，测试信息邮箱，

163邮箱是smtp.163.com        QQ邮箱是smtp.qq.com
package com.hotdas.travel.util;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

/**
 * 发邮件工具类
 */
public final class MailUtils {
    private static final String USER = ""; // 发件人称号，同邮箱地址
    private static final String PASSWORD = ""; // 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.163.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;
    }

    public static void main(String[] args) throws Exception { // 做测试用
        MailUtils.sendMail("hotdas@163.com","你好，这是一封测试邮件，无需回复。","测试邮件");
        System.out.println("发送成功");
    }



}

直接运行这个类

运行结果如下成功

 查看邮箱是否有收到

修改UserServiceImpl

package com.hotdas.travel.service.impl;

import com.hotdas.travel.dao.UserDao;
import com.hotdas.travel.dao.impl.UserDaoImpl;
import com.hotdas.travel.domain.User;
import com.hotdas.travel.service.UserService;

import com.hotdas.travel.util.UuidUtil;

public class UserServiceImpl implements UserService {
    private UserDao userDao = new UserDaoImpl();

    @Override
    public Boolean activeUser(String code) {
        //根据激活码查询用户
        User user = userDao.findByCode(code);
        if(user!=null){
            //激活该用户  status="Y"
            userDao.activeUser(user);
            return true;
        }else{
            return false;
        }
    }

    @Override
    public Boolean regirst(User user) {
        //从数据库中查询用户
        User u =   userDao.findByUsername(user.getUsername());

        //判断用户是否存在
        if (u!=null){
            //用户存在,返回false
            return false;
        }
        //激活邮箱才可以使用
        user.setCode(UuidUtil.getUuid());
        user.setStatus("N");

        //保存信息到数据库
        userDao.save(user);

        //发送邮箱给用户让用户进激活,后面doing...
        String content = "<a href='http://localhost/travel/activeUserServlet?code="+user.getCode()+"'>点击激活卓越旅游网</a> ";
        MailUtils.sendMail(user.getEmail(),content,"请激活你的卓越旅游网用户");


        return true;
    }
}

修改UserDao

package com.hotdas.travel.dao;

import com.hotdas.travel.domain.User;

public interface UserDao {
    //根据用户名查询用户信息
    User findByUsername(String username);

    //保存用户信息
    void save(User user);

    //权限用户激活码用户
    User findByCode(String code);
    
    //激活
    void activeUser(User user);
}

修改UserService

package com.hotdas.travel.service;

import com.hotdas.travel.domain.User;

public interface UserService {
    Boolean regirst(User user);
    Boolean activeUser(String code);
}

UserDaoImpl

package com.hotdas.travel.dao.impl;

import com.hotdas.travel.dao.UserDao;
import com.hotdas.travel.domain.User;
import com.hotdas.travel.util.JDBCUtils;
import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;

public class UserDaoImpl implements UserDao {

    private JdbcTemplate template = new JdbcTemplate(JDBCUtils.getDataSource());

    @Override
    public User findByUsername(String username) {
        User user =null;
        try {
            //1.定义sql
            String sql ="select * from tab_user where username=?";
            user = template.queryForObject(sql,new BeanPropertyRowMapper<User>(User.class),username);
        } catch (DataAccessException e) {
            e.printStackTrace();
        }
        return user;
    }

    @Override
    public void save(User user) {
        //1.定义sql
        String sql = "insert into tab_user(username,password,name,birthday,sex,telephone,email,status,code) values(?,?,?,?,?,?,?,?,?)";

        template.update(sql,
                user.getUsername(),
                user.getPassword(),
                user.getName(),
                user.getBirthday(),
                user.getSex(),
                user.getTelephone(),
                user.getEmail(),
                user.getStatus(),
                user.getCode());


    }

    //根据code查询用户
    @Override
    public User findByCode(String code) {
        User user = null;
        try {
            String sql = "select * from tab_user where code = ?";
            user = template.queryForObject(sql, new BeanPropertyRowMapper<User>(User.class), code);
        } catch (DataAccessException e) {
            e.printStackTrace();
        }
        return user;
    }

    @Override
    public void activeUser(User user) {
        String sql = "update tab_user set status='Y' where uid=? ";
        template.update(sql,user.getUid());
    }
}

ActiveUserServlet

package com.hotdas.travel.web.servlet;

import com.hotdas.travel.service.UserService;
import com.hotdas.travel.service.impl.UserServiceImpl;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@WebServlet("/activeUserServlet")
public class ActiveUserServlet extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //进行邮箱激活
        String code = request.getParameter("code");
        if (code!=null){
            UserService userService = new UserServiceImpl();
            Boolean flag =  userService.activeUser(code);

            //提示信息
            String msg = "";
            if (flag){
                //激活
                msg="激活成功,请<a href='login.html'>登录</a>";
            }else{
                //激活夫败
                msg="激活失败,请联系管理员!";
            }
            response.setCharacterEncoding("utf-8");
            response.setContentType("text/html;charset=utf-8");
            response.getWriter().write(msg);
        }
    }

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

四、测试

1.启动并运行

2.注册一个用户，邮箱需要写对，不然收不到激活信息 

3.跳转到这个页面成功

 4.在邮箱里面查看

5.点击邮箱里面的链接

6.点击登录，跳转到登录首页 

7.在数据库中查看数据，status为Y为激活成功

五、注册失败，遇到的bug

 解决方法，在JDBCUtils的/druid.properties，去掉/

2.邮箱后缀错误报错

javax.mail.AuthenticationFailedException: 535 Login Fail. Please enter your authorization code to login. More information in http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

	at com.hotdas.travel.util.MailUtils.sendMail(MailUtils.java:62)
	at com.hotdas.travel.util.MailUtils.main(MailUtils.java:71)

解决方法，如下图中qq.com 修改成163.com,就可以解决了

 

3. 输入中文到数据库变成？

解决方法，在druid.properies,连接数据库上防止乱码代码

driverClassName=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/travel2?useSSL=false&characterEncoding=utf-8
username=root
password=123456
initialSize=5
maxActive=10
maxWait=13000
