一.软件安装及资源准备

1.下载并安装易邮邮箱服务器和Foxmail邮箱客户端

易邮邮箱服务器下载地址：https://download.csdn.net/download/qq_20788055/10496104

Foxmail邮箱客户端下载地址：https://download.csdn.net/download/qq_20788055/10496096



2.创建邮箱账号（直接点击“新账号”创建）

3.添加邮箱账号至FoxMail客户端

4.所需jar包下载地址：https://download.csdn.net/download/qq_20788055/10495554

二.创建数据库及开发项目

1.创建数据表（regist）

2.开发项目

（1）创建实体类UserVO

public class UserVO {
	private String uid;
	private String username;
	private String password;
	private String nickname;
	private String email;
	private String state;
	private String code;
	
	public String getUid() {
		return uid;
	}
	public void setUid(String uid) {
		this.uid = uid;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getNickname() {
		return nickname;
	}
	public void setNickname(String nickname) {
		this.nickname = nickname;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	public String getState() {
		return state;
	}
	public void setState(String state) {
		this.state = state;
	}
	public String getCode() {
		return code;
	}
	public void setCode(String code) {
		this.code = code;
	}

}

（2）创建控制层--RegistServlet

package com.javamail.servlet;

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

import com.javamail.service.UserService;
import com.javamail.service.impl.UserServiceImpl;
import com.javamail.utils.UUIDUtil;
import com.javamail.vo.UserVO;

/**
 * Servlet implementation class UserServlet
 */
public class RegistServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public RegistServlet() {
        super();
        // TODO Auto-generated constructor stub
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		//response.getWriter().append("Served at: ").append(request.getContextPath());
		request.setCharacterEncoding("UTF-8");
		
		//获取数据
		String username=request.getParameter("yourname");
		String password=request.getParameter("yourpass");
		String nickname=request.getParameter("nickname");
		String email=request.getParameter("youremail");
		
		//封装数据
		UserVO user=new UserVO();
		user.setUid(UUIDUtil.getUUID());
		user.setUsername(username);
		user.setNickname(nickname);
		user.setPassword(password);
		user.setEmail(email);
		user.setState("0");//0-未激活  1-已激活
		user.setCode(UUIDUtil.getUUID()+UUIDUtil.getUUID());
		
		//保存数据
		UserService userService=new UserServiceImpl();
		userService.regist(user);
		
		//页面跳转
		request.setAttribute("msg", "您已注册成功，请去邮箱激活！");
		request.getRequestDispatcher("/msg.jsp").forward(request, response);
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		doGet(request, response);
	}

}

（3）创建业务层--UserService

package com.javamail.service.impl;

import com.javamail.dao.UserDAO;
import com.javamail.dao.impl.UserDAOImpl;
import com.javamail.service.UserService;
import com.javamail.utils.MailUtil;
import com.javamail.vo.UserVO;

public class UserServiceImpl implements UserService{

	@Override
	public void regist(UserVO user) {
		
		//将数据存入数据库
		UserDAO userDAO=new UserDAOImpl();
		userDAO.regist(user);
		
		//发送激活邮件
		MailUtil.sendMail(user.getEmail(), user.getCode());
	}

	@Override
	public UserVO findUserByCode(String code) {
		UserDAO userDAO=new UserDAOImpl();
		return userDAO.findUserByCode(code);
	}

	@Override
	public void updateUser(UserVO user) {
		UserDAO userDAO=new UserDAOImpl();
		userDAO.updateUser(user);
		
	}

}

（4）编写持久层--UserDAO

其中用到LZ自己封装的JDBC工具类，源码地址：https://github.com/Jasper2s/Study_Imooc/tree/master/JavaMail/src/com/javamail/utils

package com.javamail.dao.impl;

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

import com.javamail.dao.UserDAO;
import com.javamail.utils.JDBCUtil;
import com.javamail.vo.UserVO;

public class UserDAOImpl implements UserDAO{

	@Override
	public void regist(UserVO user) {
		Connection conn=null;
		PreparedStatement st=null;
		ResultSet rs=null;
		JDBCUtil jdbcUtil=JDBCUtil.getInstance();
		try {
			conn=jdbcUtil.getConnection();
			String sql="insert into regist values(?,?,?,?,?,?,?)";
			st=conn.prepareStatement(sql);
			st.setString(1, user.getUid());
			st.setString(2, user.getUsername());
			st.setString(3, user.getPassword());
			st.setString(4, user.getNickname());
			st.setString(5, user.getEmail());
			st.setString(6, user.getState());
			st.setString(7, user.getCode());
			st.execute();
		} catch (Exception e) {
			e.printStackTrace();
		} finally{
			jdbcUtil.close(rs, st, conn);
		}
		
	}

	@SuppressWarnings("null")
	@Override
	public UserVO findUserByCode(String code) {
		Connection conn=null;
		PreparedStatement st=null;
		ResultSet rs=null;
		UserVO user=new UserVO();
		JDBCUtil jdbcUtil=JDBCUtil.getInstance();
		try {
			conn=jdbcUtil.getConnection();
			String sql="select * from regist where code=?";
			st=conn.prepareStatement(sql);
			st.setString(1, code);
			rs=st.executeQuery();
			while(rs!=null&&rs.next()){
				String uid=rs.getString("uid");
				String username=rs.getString("username");
				String nickname=rs.getString("nickname");
				String email=rs.getString("email");
				String state=rs.getString("state");
				
				user.setUid(uid);
				user.setUsername(username);
				user.setNickname(nickname);
				user.setEmail(email);
				user.setState(state);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}finally{
			jdbcUtil.close(rs, st, conn);
		}
		return user;
	}

	@Override
	public void updateUser(UserVO user) {
		Connection conn=null;
		PreparedStatement st=null;
		ResultSet rs=null;
		JDBCUtil jdbcUtil=JDBCUtil.getInstance();
		try {
			conn=jdbcUtil.getConnection();
			String sql="update regist set username=?,password=?,nickname=?,email=?,state=?,code=? where uid=?";
			st=conn.prepareStatement(sql);
			st.setString(1, user.getUsername());
			st.setString(2, user.getPassword());
			st.setString(3, user.getNickname());
			st.setString(4, user.getEmail());
			st.setString(5, user.getState());
			st.setString(6, user.getCode());
			st.setString(7, user.getUid());
			st.execute();
		} catch (Exception e) {
			e.printStackTrace();
		} finally{
			jdbcUtil.close(rs, st, conn);
		}
	}

}

（5）编写邮箱发送的工具类--MailUtil

发送激活邮件的一般步骤：创建连接对象连接到邮箱服务器-->创建邮件对象（设置发件人，收件人，主题，正文）-->发送邮件

package com.javamail.utils;

import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMessage.RecipientType;

/**
 * 邮件发送工具类
 * @author qiuzhiwen
 *
 */
public class MailUtil {
	
	public static void sendMail(String to,String code){
		Properties props=new Properties();
		//props.setProperty("host", "");
		//1.创建连接对象，连接到邮箱服务器
		Session session=Session.getInstance(props, new Authenticator() {
			@Override
			protected PasswordAuthentication getPasswordAuthentication() {
				return new PasswordAuthentication("[email protected]", "123");
			}
		});
		//2.创建邮件对象
		Message message=new MimeMessage(session);
		try {
			//设置发件人
			message.setFrom(new InternetAddress("[email protected]"));
			//设置收件人
			message.setRecipient(RecipientType.TO, new InternetAddress(to));
			//设置邮件的主题
			message.setSubject("来自XXX网站的激活邮件");
			//设置邮件的正文
			message.setContent("<h1>来自XXX网站的激活邮件,激活请点击以下链接：</h1><br/><h3><a href='http://localhost:8080/JavaMail/ActiveServlet?code="+code+"'>http://localhost:8080/JavaMail/ActiveServlet?code="+code+"</a></h3>", "text/html;charset=UTF-8");
			//3.发送激活邮件
			Transport.send(message);
		} catch (Exception e) {
			e.printStackTrace();
		} 
	}

}

（6）注册页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

  </style>
</head>
<body>

  
  <script type="text/javascript">

			<input type="reset" value="取消"/></b>
		</form>
	</div>
</body>
</body>
</html>

三.启动项目

浏览器访问http://localhost:8080/JavaMail/regist.jsp

输入信息进行提交

查看邮箱，点击“收取”可以看到一封新邮件：


查看数据库（state为0，表示未激活）


然后点击激活链接地址

再查看数据库（state为1，表示已激活）
