Test类

package com.fighting.email;

import javax.mail.internet.MimeBodyPart;

public class MailTest {
	 public static void main(String[] args) {
	        String smtp ="smtp.qq.com";//SMTP服务器地址
	        String from = "helloworld6379@qq.com";
	        String to = "1208286977@qq.com";
	        String copyto="372528890@qq.com,980301925@qq.com";
	        String subject = " 狗年大吉";
//	        String content ="<h1>狗年大吉吧</h1>";
	        MimeBodyPart img = new MimeBodyPart();

	        String content ="<div style='color:red;font-size:18px;'>从QQ发来的邮件</div>我这里有一张自拍";
	        //正文中的图片
	        String imgFile="E:\\picture\\study\\401.PNG";
	        //附件
	        String filename = "E:\\picture\\study\\401.PNG,E:\\picture\\study\\401.PNG";
	        //163邮箱用户名就是去掉@163.com
	        String username = "helloworld6379";
	        String password = "jexbhirasjwifqpx";

//	        Mail.send(smtp,from,to,subject,content,username,password);
	        Mail.sendAndCcWithFile(smtp,from,to,subject,content,imgFile,username,password,copyto,filename);
	    }

}

　

password是你开启IMAP/SMTP服务时发来的密码

　　

效果：
