使用Java实现给QQ邮箱发送验证码
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", "smtp.qq.com");
//端口号，QQ邮箱端口587
props.put("mail.smtp.port", "587");
// 此处填写，写信人的账号
props.put("mail.user", "[email protected]");
// 此处填写16位STMP口令
props.put("mail.password", "nwjvkvlikjefdb");
// 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("[email protected]"); 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[]{"[email protected]","[email protected]","[email protected]","[email protected]"};
//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 stringList = new ArrayList<>();
stringList.add("[email protected]");
//stringList.add("[email protected]");
//stringList.add("[email protected]");
stringList.add("[email protected]");
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
