使用Java实现给QQ邮箱发送验证码
1.给QQ邮箱发送字符串（验证码）
public class QQYte {public static void main(String[] args) {// 创建Properties 类用于记录邮箱的一些属性Properties props = new Properties();// 表示SMTP发送邮件，必须进行身份验证props.put("mail.smtp.auth", "true");//此处填写SMTP服务器props.put("mail.smtp.host", "");//端口号，QQ邮箱端口587props.put("mail.smtp.port", "587");// 此处填写，写信人的账号props.put("mail.user", "1781484543@");// 此处填写16位STMP口令props.put("mail.password", "nwjvnvkvlikjefdb");// 构建授权信息，用于进行SMTP进行身份验证Authenticator authenticator = new Authenticator() {protected PasswordAuthentication getPasswordAuthentication() {// 用户名、密码String userName = props.getProperty("mail.user");String password = props.getProperty("mail.password");return new PasswordAuthentication(userName, password);}};// 使用环境属性和授权信息，创建邮件会话Session mailSession = Session.getInstance(props, authenticator);// 创建邮件消息MimeMessage message = new MimeMessage(mailSession);// 设置发件人try {InternetAddress form = new InternetAddress(props.getProperty("mail.user"));message.setFrom(form);// 设置收件人的邮箱//InternetAddress to = new InternetAddress("xujr3@"); 有多少个邮箱，发送给多少人//一般数组是不能够添加元素的 刚开始初始化的时候数组就已经规定好了长度//String[] strings = new String[]{"1781484543@","2385824854@","2498068709@","xujr3@"};//使用list集合代替 数组方便又快捷 ArrayList本身是个数组（底层是用数组实现的）List<String> stringList = new ArrayList<>();stringList.add("1781484543@");//stringList.add("2385824854@");//stringList.add("2498068709@");stringList.add("xujr3@");for (String s : stringList) {System.out.println("s = " + s);InternetAddress to2 = new InternetAddress(s);//message.setRecipient(RecipientType.TO, to);message.setRecipient(RecipientType.TO,to2);//使用UUID自动生成6位验证码String substring = UUID.randomUUID().toString();// 设置邮件标题message.setSubject("您的验证码信息如下");// 设置邮件的内容体message.setContent(substring, "text/html;charset=UTF-8");// 设置邮件消息内容、包含附件Multipart msgPart = new MimeMultipart();message.setContent(msgPart);MimeBodyPart body = new MimeBodyPart();//正文//MimeBodyPart attach = new MimeBodyPart();//附件msgPart.addBodyPart(body);//msgPart.addBodyPart(attach);//设置正文内容String uuid=UUID.randomUUID().toString();//body.setContent("记得观看哟，更多精彩视频请关注抖音：20762851861","text/html;charset=utf-8");body.setContent(uuid,"text/html;charset=utf-8");//设置附件内容//attach.setDataHandler(new DataHandler(new FileDataSource("C:\\Users\\17814\\Desktop\\商品表信息.xls")));//attach.setFileName((MimeUtility.encodeText("旅行视频合集.mp4")));message.saveChanges();//邮件的创建时间// message.setSentDate(new Date());// 最后当然就是发送邮件啦Transport.send(message);}} catch (MessagingException e) {e.printStackTrace();}}}
注意：以上也可实现附件的上传
2.发送Excel表格
