java实现表单注册邮箱验证功能

一.前言:

• 学习技术对于我们来说是无止境的,只有不断地学习,才能适应技术的快节奏迭代.

二.具体操作(我用的是163邮箱,maven项目)

1.在邮箱中开启 POP3/SMTP/IMAP

2.设置授权码(163邮箱授权码是没有时效性的)

3.配置pom.xml

		<dependency>
           <groupId>org.springframework</groupId>
           <artifactId>spring-context-support</artifactId>
           <version>4.2.6.RELEASE</version>
       </dependency>
       
       <dependency>
           <groupId>javax.mail</groupId>
           <artifactId>mail</artifactId>
           <version>1.4.7</version>
   	</dependency>`

4.主方法(这里只是测试,具体该怎么调用根据自己的需求来进行修改)

import com.sun.net.ssl.internal.ssl.Provider;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.security.Security;
import java.util.Date;
import java.util.Properties;


public class MailSender {
    private static MimeMessage message;

    public static void main(String[] args) throws MessagingException {

        Security.addProvider(new Provider());
        final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
        //163邮箱服务器
        String smtpHost="smtp.163.com";
        //邮箱用户名，即163账号
        final String username = "这里填发送端163邮箱账号";
        //邮箱授权码
        final String password = "这里填邮箱的授权码";
        //要发送到的邮箱
        String to = "这里填目标邮箱";
        //自己的邮箱
        String from = "这里填发送端163邮箱账号";
        Transport transport;

        Properties props = new Properties();
        props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
        props.setProperty("mail.smtp.socketFactory.fallback", "false");
        props.setProperty("mail.smtp.port", "994");
        props.setProperty("mail.smtp.socketFactory.port", "994");
        props.setProperty("mail.smtp.auth", "true");
        props.put("mail.smtp.host",smtpHost);
        props.put("mail.smtp.username", username);
        props.put("mail.smtp.password", password);
        Session session = Session.getDefaultInstance(props,  new Authenticator() {
            //身份认证
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
            }
        });
        InternetAddress[] addresses = {new InternetAddress(to)};
        message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.setRecipients(Message.RecipientType.TO,addresses);
        //邮件标题
        message.setSubject("注册验证");
        message.setSentDate(new Date());
        //编写内容
        message.setText("这里是发送内容");
        transport = session.getTransport("smtp");
        transport.connect(smtpHost, username, password);
        transport.send(message);
        System.out.println("验证发送成功");
    }
}

• 以上就是邮箱验证的相关操作,如果是使用其他的邮箱只需修改端口号和账号授权码即可,达到的效果如下图
  
• 注意:网易163邮箱一封邮件最多发送给 40 个收件人 , 每天发送限额为 50 封。
