编写程序

package com.Google;

import com.sun.mail.util.MailSSLSocketFactory;

import javax.imageio.spi.ImageInputStreamSpi;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;

public class mailTest {
    public static void main(String[] args) throws Exception {
        Properties prop = new Properties();
        prop.setProperty("mail.host","stmp.qq.com");//设置QQ邮箱服务器
        prop.setProperty("mail.transport.protocol","smtp");//发送协议
        prop.setProperty("mail.smtp.auth","true");//验证用户名和密码

        //关于QQ邮箱，还要设置SSl加密
        MailSSLSocketFactory sf = new MailSSLSocketFactory();
        sf.setTrustAllHosts(true);//信任所有主机
        prop.put("mail.smtp.ssl.enable","true");
        prop.put("mail.smtp.ssl.socketFactory",sf);

        //使用javaMail发送邮箱的五个步骤
        //1,创建整个应用程序所需的环境信息的Session对象
        Session session = Session.getDefaultInstance(prop, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                //发件人邮箱用户名，授权码(Authentication,验证)
                return new PasswordAuthentication("2034281740@qq.com", "授权码");
            }
        });
        session.setDebug(true);

        //2，通过Session获取transport对象
        Transport transport = session.getTransport();
        //3,使用邮箱的用户名和授权码，连接邮箱服务器
        transport.connect("smtp.qq.com","2034281740@qq.com", "授权码");
        //4，编写内容
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress("2034281740@qq.com"));//设置发件人
        message.setRecipient(Message.RecipientType.TO, new InternetAddress("2034281740@qq.com"));//设置收件人
        message.setSubject("叫我靓仔");//设置邮件标题
        message.setContent("叼毛，叼毛","text/html;charset=UTF-8");
        //5，发送邮箱
        transport.sendMessage(message, message.getAllRecipients());
