JavaMail Error: javax.mail.AuthenticationFailedException

Question

我正在制作一个向我的电子邮件发送信息的程序，我正在参考给定的java代码。但我得到认证失败错误。有没有人知道发送SMTP邮件不允许从gmail和雅虎不安全?请帮帮我。

import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import java.util.*;
import java.io.*;
public class Emailer
{
  private static final String SMTP_HOST_NAME = "smtp.live.com";
  private static final String SMTP_AUTH_USER = "[e-mail]";
  private static final String SMTP_AUTH_PWD  = "spidermonkey";
  private static final String emailMsgTxt      = "Online Order Confirmation Message. Also include the Tracking Number.";
  private static final String emailSubjectTxt  = "HELEEEELEQWEWEQ!!!";
  private static final String emailFromAddress = "[e-mail]";
  // Add List of Email address to who email needs to be sent to
  private static final String[] emailList = {"[e-mail]"};
  public static void main(String emailBody) throws Exception
  {
    Emailer smtpMailSender = new Emailer();
    smtpMailSender.postMail( emailList, emailSubjectTxt, emailBody, emailFromAddress);
    System.out.println("Sucessfully Sent mail to All Users");
  }
  public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException {
     boolean debug = false;
     //Set the host smtp address
     Properties props = new Properties();
     props.put("mail.smtp.host", SMTP_HOST_NAME);
     props.put("mail.smtp.auth", "true");
    Authenticator auth = new SMTPAuthenticator();
    Session session = Session.getDefaultInstance(props, auth);
    session.setDebug(debug);
    // create a message
    Message msg = new MimeMessage(session);
    // set the from and to address
    InternetAddress addressFrom = new InternetAddress(from);
    msg.setFrom(addressFrom);
    InternetAddress[] addressTo = new InternetAddress[recipients.length];
    for (int i = 0; i < recipients.length; i++)
    {
        addressTo[i] = new InternetAddress(recipients[i]);
    }
    msg.setRecipients(Message.RecipientType.TO, addressTo);

    // Setting the Subject and Content Type
    msg.setSubject(subject);
    msg.setContent(message, "text/plain");
    Transport.send(msg);
 }

/**
* SimpleAuthenticator is used to do simple authentication
* when the SMTP server requires it.
*/
private class SMTPAuthenticator extends javax.mail.Authenticator
{
    private Session createSmtpSession() {
          final Properties props = new Properties();
          props.setProperty("mail.smtp.host", "smtp.live.com");
          props.setProperty("mail.smtp.auth", "true");
          props.setProperty("mail.smtp.port", "" + 587);
          props.setProperty("mail.smtp.starttls.enable", "true");
          // props.setProperty("mail.debug", "true");
          return Session.getDefaultInstance(props, new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
              return new PasswordAuthentication("[e-mail]", "spidermonkey");
            }
          });
        }
}
}

然而，每当我运行这个，我得到以下错误消息:

Exception in thread "main" javax.mail.AuthenticationFailedException: failed to connect, no password specified?

您已创建

private Session createSmtpSession() 

但是你没有使用它。

这是你的解决方案。

public void postMail( String recipients[ ], String subject, String message , String from)
throws MessagingException {
Session session = null;
 Properties props = new Properties();
    props.setProperty("mail.smtp.host", SMTP_HOST_NAME );
    props.setProperty("mail.smtp.auth", "true");
    props.setProperty("mail.smtp.port", "" + 587);
    props.setProperty("mail.smtp.starttls.enable", "true");
    // props.setProperty("mail.debug", "true");
    session = Session.getInstance(props, new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(SMTP_AUTH_USER,SMTP_AUTH_PWD);
        }
    });
session.setDebug(debug);
// create a message
Message msg = new MimeMessage(session);
// set the from and to address
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++)
{
    addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);

// Setting the Subject and Content Type
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
}
