获取“javax.mail.AuthenticationFailedException：连接失败”错误 [英] Getting the "javax.mail.AuthenticationFailedException: failed to connect" Error

问题描述

我想要做什么：发送带有smtp.live.com主机的基本电子邮件，以使用以下代码向使用Java程序的人发送电子邮件：

What I Want To Do: Send a basic email with the smtp.live.com host to email to someone using a Java Program using this code below:

import java.util.*;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.sun.mail.smtp.SMTPTransport;

public class emailTest {

    public static void main(String[] args) {
        String to = "[e-mail]";
        String from = "[e-mail]";

        Properties props = new Properties();
        props.setProperty("mail.transport.protocol", "smtp");
        props.setProperty("mail.host", "smtp.live.com");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");


        Session session = Session.getDefaultInstance(props);
        session.setDebug(true);

        try {
            MimeMessage message = new MimeMessage(session);

            message.setFrom(new InternetAddress(from));

            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

            message.setSubject("Java");

            message.setText("Java");

            Transport trans = session.getTransport("smtp");
            trans.connect("smtp.live.com", 587, "[e-mail]", "password");
            Transport.send(message);

            System.out.println("Message Sent!");

        } catch (MessagingException mex) {
            mex.printStackTrace();
        }
    }

}

问题：当我尝试发送电子邮件时，我收到此错误。

The Problem: When I try to send the email, I get this error.

javax.mail.AuthenticationFailedException: failed to connect
at javax.mail.Service.connect(Service.java:322)
at javax.mail.Service.connect(Service.java:172)
at javax.mail.Service.connect(Service.java:121)
at javax.mail.Transport.send0(Transport.java:190)
at javax.mail.Transport.send(Transport.java:120)
at emailTest.main(emailTest.java:39)

我的问题： / strong>我只是想知道我做错了什么，因为我花了几个小时试图找到不同的方法来解决这个问题。

My Question: I just want to know what I'm doing wrong as I've spent a few hours trying to find different ways on how to fix this.

推荐答案

好的，我很快就想出了我做错了什么。我不能使用Transport.send（message）发送消息。

Ok, I soon figured out what I was doing wrong. I can't use Transport.send(message) to send the message.

需要更改：相反，我必须使用trans.sendMessage（message，message.getAllRecipients（））。

Changes Needed: Instead, I have to use trans.sendMessage(message, message.getAllRecipients()).

这是固定代码：

    import java.util.*;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

import com.sun.mail.smtp.SMTPTransport;

public class emailTest {

    public static void main(String[] args) {
        String to = "[e-mail]";
        String from = "[e-mail]";

        Properties props = new Properties();
        props.setProperty("mail.transport.protocol", "smtp");
        props.setProperty("mail.host", "smtp.live.com");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");


        Session session = Session.getDefaultInstance(props);
        session.setDebug(true);

        try {
            MimeMessage message = new MimeMessage(session);

            message.setFrom(new InternetAddress(from));

            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

            message.setSubject("Java");

            message.setText("Java");

            Transport trans = session.getTransport("smtp");
            trans.connect("smtp.live.com", 587, "[e-mail]", "password");
            trans.sendMessage(message, message.getAllRecipients());

            System.out.println("Message Sent!");

        } catch (MessagingException mex) {
            mex.printStackTrace();
        }
    }

}
