本程序是基于上文的改进完成。
开发及运行环境：eclipse jdk1.7 tomcat7
本程序以实现最基本功能为主，所用知识很基础，理解后可自行完善。

实现思路
实现思路
准备工作
- 开启SMTP服务
在 QQ 邮箱里的 设置->账户里开启 SMTP 服务

- 注意开启完之后，QQ 邮箱会生成一个授权码，在代码里连接邮箱使用这个授权码而不是原始的邮箱密码，这样可以避免使用明文密码。也可以使用明文密码，但是会有密码泄露的风险。（借用原作者的图吧，省的再截图）
注
这里的授权码先记下来，第4步要用到。

程序结构
实现步骤
- 1、 建数据库、表
- 2、 User类（实体类）
- 3、 UserDao类（与数据库交互）
- 4、 SendMailUtils类（发送邮件）
- 5、 UUIDUtils（生成随机字符串code）
- 6、 RegistServlet（注册账户）
- 7、 ActiveServlet（激活账户）
- 8、 index.jsp（输入界面）
- 9、 success.jsp（成功界面）
具体实现
1、 建数据库、表
/*
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(30) NOT NULL,
`password` varchar(30) NOT NULL,
`nickname` varchar(30) NOT NULL,
`email` varchar(30) NOT NULL,
`state` int(11) DEFAULT '0',
`code` varchar(64) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
2、 User类（实体类）
package com.look.bean;
public class User {
private Integer id;
private String username;
private String password;
private String nickname;//昵称
private String email;
private Integer state;//状态
private String code;//随机码
getter and setter...
}
3、 UserDao类（与数据库交互）
package com.look.dao;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import com.look.bean.User;
public class UserDao {
private static Connection conn;
// 获取数据库连接
public void getConn() {
try {
Class.forName("com.mysql.jdbc.Driver");
String url = "jdbc:mysql://localhost:3306/javamail";
String rootname = "root";
String rootpass = "123456";
conn = DriverManager.getConnection(url, rootname, rootpass);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
// 注册
public void regist(User user) {
try {
String sql = "insert into user(username,password,nickname,email,code) values(?,?,?,?,?)";
PreparedStatement pstmt;
pstmt = conn.prepareStatement(sql);
pstmt.setString(1, user.getUsername());
pstmt.setString(2, user.getPassword());
pstmt.setString(3, user.getNickname());
pstmt.setString(4, user.getEmail());
pstmt.setString(5, user.getCode());
pstmt.executeUpdate();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
// 激活
public void activeByCode(String code) {
//状态标志置为1，code置空
String sql = "update user set state=1,code=null where code=?";
PreparedStatement pstmt;
try {
pstmt = conn.prepareStatement(sql);
pstmt.setString(1, code);
pstmt.executeUpdate();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
// 关闭数据库连接
public void closeConn() {
if (conn != null) {
try {
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
注
mysql的账号密码需要修改为自己的账号密码。
4、 SendMailUtils类（发送邮件）
package com.look.util;
import java.security.GeneralSecurityException;
import java.util.Properties;
import javax.mail.Address;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import com.sun.mail.util.MailSSLSocketFactory;
public class SendMailUtils {
public static void sendMail(String to, String code)
throws GeneralSecurityException, MessagingException {
Properties props = new Properties();
// 开启debug调试
// props.setProperty("mail.debug", "true");
// 发送服务器需要身份验证
props.setProperty("mail.smtp.auth", "true");
// 设置邮件服务器主机名
props.setProperty("mail.host", "smtp.qq.com");
// 发送邮件协议名称
props.setProperty("mail.transport.protocol", "smtp");
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
props.put("mail.smtp.ssl.enable", "true");
props.put("mail.smtp.ssl.socketFactory", sf);
Session session = Session.getInstance(props);
Message msg = new MimeMessage(session);
msg.setSubject("本邮件用于测试");
// send text to the mail
// StringBuilder builder = new StringBuilder();
// builder.append("点击测试<a href='http://loc alhost:8080/ssm/listCategory'>listCategory1</a>");
// msg.setText(builder.toString());
msg.setContent(
"<a href='http://localhost:8080/javamail/ActiveServlet?code="
+ code + "'>点我激活</a>", "text/html;charset=UTF-8");
msg.setFrom(new InternetAddress("1478161802@qq.com"));
Transport transport = session.getTransport();
transport.connect("smtp.qq.com", "1478161802@qq.com",
"hsvsqhofljqtjgdi");
transport.sendMessage(msg, new Address[] { new InternetAddress(to) });
transport.close();
}
}
注：
msg.setFrom(new InternetAddress("12345678@qq.com"));和transport.connect("smtp.qq.com", "12345678@qq.com","hsvsqhofljqtjgdi");中的12345678@qq.com需要替换为你自己的qq邮箱，hsvsqhofljqtjgdi要替换为自己的授权码。
5、 UUIDUtils（生成随机字符串code）
package com.look.util;
import java.util.UUID;
public class UUIDUtils {
public static String getUUID() {
return UUID.randomUUID().toString().replace("-", "")
+ UUID.randomUUID().toString().replace("-", "");
}
}
6、 RegistServlet（注册账户）
package com.look.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.security.GeneralSecurityException;
import javax.mail.MessagingException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.look.bean.User;
import com.look.dao.UserDao;
import com.look.util.SendMailUtils;
import com.look.util.UUIDUtils;
public class RegistServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public void init() throws ServletException {
super.init();
}
public void service(HttpServletRequest request, HttpServletResponse response) {
// 获取数据
String username = request.getParameter("username");
String password = request.getParameter("password");
String nickname = request.getParameter("nickname");
String email = request.getParameter("email");
// 封装数据
User user = new User();
user.setUsername(username);
user.setPassword(password);
user.setNickname(nickname);
user.setEmail(email);
user.setCode(UUIDUtils.getUUID());
System.out.println(user.getEmail() + "\t" + user.getCode());
// 注册
UserDao dao = new UserDao();
dao.getConn();
dao.regist(user);
dao.closeConn();
// 发送邮件
try {
SendMailUtils.sendMail(email, user.getCode());
request.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
out.print("<html><head><meta charset='utf-8'/></head><body><p>邮件已经发送到"
+ user.getEmail() + "中，请登录邮箱点击链接完成验证</p></body></html>");
out.flush();
out.close();
} catch (GeneralSecurityException | MessagingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public void destroy() {
super.destroy();
}
}
7、 ActiveServlet（激活账户）
package com.look.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.look.dao.UserDao;
public class ActiveServlet extends HttpServlet
{
private static final long serialVersionUID = 1L;
public void init() throws ServletException {
super.init();
}
public void service(HttpServletRequest request,
HttpServletResponse response) {
// 获取数据
String code = request.getParameter("code");
// 数据库判断对应code是否存在，（这里就不进行判断了，直接进行比对）state=1&code=null代表激活
UserDao dao = new UserDao();
dao.getConn();
dao.activeByCode(code);
dao.closeConn();
// 重定向success.jsp
try {
request.getRequestDispatcher("success.jsp").forward(request,
response);
} catch (ServletException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public void destroy() {
super.destroy();
}
}
8、 index.jsp（输入界面）
