SMTP 使用 SSL 协议 端口 465 / 587

非 SSL 通道 端口 25

首先导入mail依赖包

javax.mail - mail - 1.4.7

final Properties props = new Properties();

props.put("mail.smtp.auth", email.getSmtpAuth());

props.put("mail.smtp.host", email.getSmtpService());

props.put("mail.transport.protocol", "smtp");

props.put("mail.debug", "false");

props.put("mail.smtp.starttls.enable", "true");

props.put("mail.smtp.port", email.getSmtpPort());

MailSSLSocketFactory sf = new MailSSLSocketFactory();

sf.setTrustAllHosts(true);

props.put("mail.smtp.ssl.enable", "true");

props.put("mail.smtp.ssl.socketFactory", sf);

Authenticator authenticator = new Authenticator() {

    protected PasswordAuthentication getPasswordAuthentication() {

        String userName = email.getFromMailAddress();

        String password = email.getFromMailStmpPwd();

        return new PasswordAuthentication(userName, password);}};

Session mailSession = Session.getInstance(props, authenticator);

MimeMessage message = new MimeMessage(mailSession);

String nickName = MimeUtility.encodeText(email.getNickname());

InternetAddress from = new InternetAddress(nickName + "<" + email.getFromMailAddress() + ">");

message.setFrom(from);

message.setSubject(email.getTitle());

if (email.getContentType().equals(MailContentTypeEnum.HTML.getValue())) {

    message.setContent(email.getContent(), email.getContentType());

} else if (email.getContentType().equals(MailContentTypeEnum.TEXT.getValue())) {

    message.setText(email.getContent());

}

List params = email.getList();

for (int i = 0; i < params.size(); i++) {

    try {

        InternetAddress to = new InternetAddress(params.get(i));

        message.setRecipient(Message.RecipientType.TO, to);

        Transport.send(message);

        logger.info("send to " + params.get(i) + " success");

    } catch (Exception e) {

        logger.error(e.getMessage());

        logger.info("send to " + params.get(i) + " unsuccess");

        continue;

    }

}
