Question

我正在按照教程创建一个使用Hotmail STMP发送邮件的类。不知怎的，我得到了错误：

“javax.mail.NoSuchProviderException：没有smtp的提供者”

我试图ping并telnet到smtp.live.com但我没有回复。我不确定代码是不正确还是因为hotmail的SMTP。有人可以给我一个建议吗？

感谢您的帮助。

在主类中，我只调用构造函数并发送（）

Answer 1

你试过25端口吗？我的邮箱设置显示smtp端口为25。

Answer 2

我使用了您的代码，并且能够发送电子邮件而没有错误。

new Mail("your email here", "your password here").send();

这里有两个构造函数，没有参数的构造函数没有电子邮件和密码。

打开调试：_debuggable = true;

我正在使用JavaMail API：

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.5</version>
</dependency>

Answer 3

public static void sendEmail（）抛出异常{

    Properties props = null;
    if (props == null) {
        props = new Properties();
        props.put("mail.smtp.host", "smtp.live.com");
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.user", "mahadevmane60@hotmail.com");
        props.put("mail.smtp.pwd", "mypassword");
    }
    Session session = Session.getInstance(props, null);
    session.setDebug(true);
    Message msg = new MimeMessage(session);
    msg.setFrom(new InternetAddress("mahadevmane60@hotmail.com"));
    msg.setSubject("Auto Generated Mail");
    msg.setText("Testing Mail");
msg.setRecipient(Message.RecipientType.TO, new InternetAddress("mahadevmane60@gmail.com"));
    Transport transport = session.getTransport("smtp");
    transport.connect("smtp.live.com", 587, "mahadevmane60@hotmail.com", "Mypassword");
    transport.sendMessage(msg, msg.getAllRecipients());
    System.out.println("Mail sent successfully at ");
    transport.close();
}
