java实现发送邮件功能

项目中实现发送邮件功能，先书写一个小Demo，记录如下:

POM.XML中导入依赖

<!--  start java 提供的支持邮件发送相关业务的类 -->
        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4.7</version>
        </dependency>
        <!--  end java 提供的支持邮件发送相关业务的类 -->

package com.xiaowu;

import java.util.Properties;

import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class JavaMail {
     public static void main(String[] args) throws Exception {
            Properties props = new Properties();
            props.setProperty("mail.smtp.auth", "true");
            props.setProperty("mail.transport.protocol", "smtp");
            props.put("mail.smtp.host","smtp.163.com");// smtp服务器地址
            
            Session session = Session.getInstance(props);
            session.setDebug(true);
            
            Message msg = new MimeMessage(session);
            msg.setSubject("这是一个测试程序....");
            msg.setText("你好!这是我的第一个javamail程序---WQ");
            msg.setFrom(new InternetAddress("XXXXXXXXXXX@163.com"));//发件人邮箱(我的163邮箱)
            msg.setRecipient(Message.RecipientType.TO,
                    new InternetAddress("XXXXXXXXXXX@qq.com")); //收件人邮箱(我的QQ邮箱)
            msg.saveChanges();

            Transport transport = session.getTransport();
            transport.connect("XXXXXXXXXX@163.com","XXXXXXXXX");//发件人邮箱,授权码(可以在邮箱设置中获取到授权码的信息)
            
            transport.sendMessage(msg, msg.getAllRecipients());
            
            System.out.println("邮件发送成功...");
            transport.close();
        }
}
