我想做什么:使用以下代码向smtp.live.com主机发送基本电子邮件,以便通过电子邮件发送给使用Java程序的人:

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 = "example@live.com";
        String from = "example@live.com";

        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, "example@live.com", "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。

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:我只是想知道自己做错了什么,因为我花了几个小时试图找到解决这个问题的不同方法。

1 个答案:

答案 0 :(得分:0)

好的,我很快就弄清楚我做错了什么。我无法使用Transport.send(消息)发送消息。

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

这里是固定代码:

    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 = "example@live.com";
        String from = "example@live.com";

        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, "example@live.com", "password");
            trans.sendMessage(message, message.getAllRecipients());

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

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

}
