1，新建一个Maven项目  
2，引用依赖

<dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4.7</version>
    </dependency>

3，将邮箱账号的POP3进行开启，并获得秘钥

4，新建一个Class类，进行邮件发送

package com.a.email;
    
    import java.util.Date;
    import java.util.Properties;
    
    import javax.mail.Message;
    import javax.mail.MessagingException;
    import javax.mail.Session;
    import javax.mail.Transport;
    import javax.mail.internet.AddressException;
    import javax.mail.internet.InternetAddress;
    import javax.mail.internet.MimeMessage;
    
    public class Email2 {
    
    	
    	public static void main(String[] args) throws AddressException, MessagingException {
    		String from="XXXXXXXXXX@qq.com";//发送人邮箱账号
    		String to="XXXXXXXX@XXX.com";//接受人邮箱账号
    		String subject="这是标题";
    		String body="这是邮件内容";
    		String smtpHost="smtp.qq.com";//QQ邮箱，其他的邮箱只需要将中间部分更改为对应的名称
    		Properties properties=new Properties();
    		properties.setProperty("mail.transport.protocol", "smtp");
    		properties.setProperty("mail.smtp.host", smtpHost);
    		properties.setProperty("mail.smtp.auth", "true");
    		Session session=Session.getDefaultInstance(properties);
    		MimeMessage message=new MimeMessage(session);
    		message.setFrom(new InternetAddress(from));
    		message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
    		message.setSentDate(new Date());
    		message.setSubject(subject);
    		message.setText(body);
    		message.saveChanges();
    		session.setDebug(true);
    		Transport transport=session.getTransport("smtp");
    		transport.connect(from, "授权码");
    		transport.sendMessage(message, message.getAllRecipients());
    		transport.close();
    	}
    }
