在 Tomcat7 中获取 javax.mail.AuthenticationFailedException

Question

The program attempts to send e-mail but throws a run time exception:AuthenticationFailedException .I have used smtp protocol for sending the mail.I have used TLS.Below is my Mailsender class named SendMail.java

  package com.xxx.dashboard.mail;

  import java.util.Map;
  import java.util.Properties;
  import javax.mail.Message;
  import javax.mail.MessagingException;
  import javax.mail.PasswordAuthentication;
  import javax.mail.Session;
  import javax.mail.Transport;
  import javax.mail.internet.InternetAddress;
  import javax.mail.internet.MimeMessage;
  import com.edifixio.dashboard.configuration.ConfigurationBundle;

  public class SendMail {

  public static void sendMail(String toAddresses, String subject, String url, String name, String email){

    Map<String, String> mapdata = ConfigurationBundle.getMapdata();
    final String emailId = mapdata.get("mail_id");
    final String username = mapdata.get("mail_username");
    final String password = mapdata.get("mail_password");
    final String smtpHost = mapdata.get("mail_smtp_host");
    final String smtpPort = mapdata.get("mail_smtp_port");

    Properties props = new Properties();
    props.put("mail.smtp.auth", true);
    props.put("mail.smtp.starttls.enable", true);
    props.put("mail.smtp.host", smtpHost);
    props.put("mail.smtp.port", smtpPort);


    Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {
                                protected PasswordAuthentication getPasswordAuthentication() {

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

       try {
              Message message = new MimeMessage(session);
              message.setFrom(new InternetAddress(emailId));
              message.setRecipients(Message.RecipientType.TO,InternetAddress.parse(toAddresses));
              message.setSubject(subject);

              String text =  "<b>Hello "+name+",</b><br/><br/> Thank you for registering with WARM for monitoring of your URL."
                    + "<br/>In order to activate your account please <a href="+url+"><b>Click Here</b></a><br/><br/>"
                            + "Once you have activated your WARM account you can login to the WARM Dashboard using your Username "
                            + "<a href=\"mailto:"+email+"\">"+email+"</a>.<br/>If you are having problems with the given link, "
                                    + "please reply back to the following Email address: <a href=\"mailto:warm.xxx@gmail.com\">warm.xxx@gmail.com</a>.</br>This is a system generated mail. Please do not reply to this mail.<br/><br/>Thanks and Regards<br/>WARM Admin.";

              message.setContent(text,"text/html");
              Transport.send(message);
       } catch (MessagingException e) {
              throw new RuntimeException(e);
       }
 }

public static void main(String args[]) {
    sendMail("sumit.ghosh@xxx.com", "Hello", "h", "Rakesh", "rakesh@gmail.com");
    System.out.println("Successfully send mail to - "+toAddresses); 
  }
}

我也遇到了这个问题，我必须进入我的 Gmail 帐户设置并在“安全性”下启用“访问不太安全的应用程序”来修复它。

Answer 2

I was also trying out the simple javax mail program using the google smtp server . On receiving Authentication failed messages ,I had to goto https://www.google.com/settings/security/lesssecureapps and turn on access for less secure apps

Answer 3

1. Log in to the gmail account specified in your properties file
2. Click on the circle on your top right corner -> manage your google account -> security -> Less secure app access . Turn it on
3. Go to https://accounts.google.com/DisplayUnlockCaptcha .
4. Click on continue and logout of the gmail.
5. Test your service. Now it will establish a connection to send mails

Answer 4

Try with these properties:

mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.auth.mechanisms=login
mail.smtp.quitwait=false
mail.debug = false
mail.username=test@gmail.com
mail.password=test
mail.smtp.host=smtp.gmail.com
mail.smtp.port=587
mail.smtp.protocol=smtps

Answer 5

Your code sent mail without any exceptions in eclipse on Debian OS. Are you running any firewall or anti-virus software that might be interfering with the connection attempt?
