建立实体类发送

package com.zou.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User implements Serializable {
    private String username;
    private String password;
    private String email;
}

建立工具类发送邮件

package com.zou.util;
import com.zou.pojo.User;
import com.sun.mail.util.MailSSLSocketFactory;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Sendmail extends Thread{
    private String from ="2246781190@qq.com";
    private String username ="2246781190@qq.com";
    private String password ="udgyxytarwlgecae";
    private String host="smtp.qq.com";
    private User user;
    public Sendmail(User user) {
        this.user = user;
    }
    @Override
     public void run() {
        try {
            Properties prop = new Properties();
            prop.setProperty("mail.host", "smtp.qq.com");//设置请求邮件服务器
            prop.setProperty("mail.transport.protocol", "smtp");//邮件发送协议
            prop.setProperty("mail.smtp.auth", "true");//需要验证用户名密码
            //关于qq邮箱还要设置ssl加密，加上以下代码
            MailSSLSocketFactory sf = new MailSSLSocketFactory();
            sf.setTrustAllHosts(true);
            prop.put("mail.smtp.ssl.enable", "true");
            prop.put("mail.smtp.ssl.socketFactory", sf);
            Session session = Session.getDefaultInstance(prop, new Authenticator() {
                public PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("2246781190@qq.com", "utrwlgecae");
                }
            });
            session.setDebug(true);
            //通过session得到transport对象
            Transport transport = session.getTransport();
            transport.connect("smtp.qq.com", "2246781190@qq.com", "uytrwlgecae");
            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress("2246781190@qq.com"));
            message.setRecipient(Message.RecipientType.TO, new InternetAddress(user.getEmail()));
            message.setSubject("用户注册事件");
            String info="恭喜您注册成功，您的用户名："+user.getUsername()+",您的密码;"+user.getPassword()+",请妥善你保管，如有问题请联系客服";
            message.setContent(info,"text/html;charset=UTF-8");
            message.saveChanges();
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();
        }catch (Exception e){
            throw new RuntimeException(e);
        }
    }
}



建立jsp主页

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>$Title$</title>
</head>
<body>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>注册</title>
</head>
<body>
<form action="${pageContext.request.contextPath}/RegisterServlet.do" method="post">
    用户名：<input type="text" name="username"><br/>
    密码：<input type="password" name="password"><br/>
    邮箱：<input type="text" name="email"><br/>
    <input type="submit" value="注册">
</form>
</body>
</html>
</body>
</html>
发送后跳转jsp页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>
  网站提示
</h1>
${message}
</body>
</html>
跳转内容

package com.zou.servlet;

import com.zou.pojo.User;
import com.zou.util.Sendmail;

import javax.servlet.ServletException;
import java.io.IOException;

public class RegisterServlet extends javax.servlet.http.HttpServlet{
    protected void doPost(javax.servlet.http.HttpServletRequest request,javax.servlet.http.HttpServletResponse response)throws ServletException,IOException {
    String username =request.getParameter("username");
    String password =request.getParameter("password");
    String email =request.getParameter("email");
        User user = new User(username,password,email);
        Sendmail send=new Sendmail(user);
        send.start();
        request.setAttribute("message","注册成功，我们已经发了一封电子邮件，如网络不稳定，可能过一会才能收到！！");
        request.getRequestDispatcher("info.jsp").forward(request,response);
    }
    protected void doGet(javax.servlet.http.HttpServletRequest request,javax.servlet.http.HttpServletResponse response)throws ServletException,IOException{
    }
}
