javax.mail.AuthenticationFailedException：未能连接，未指定密码？但我知道密码是好的

大家好！
用JavaMail API的工作过程中，我有一个问题，我在尝试如下发送邮件时异常：javax.mail.AuthenticationFailedException：未能连接，未指定密码？但我知道密码是好的

javax.mail.AuthenticationFailedException：连接失败，没有密码指定

下面是代码：

package sendmail; 

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

/** 
* Created by caesar-84 on 9/28/16. 
*/ 
public class SslGmailSender 
{ 
    private String username; 
    private String password; 
    private Properties props; 

    public SslGmailSender(String username, String password) 
    { 
     this.username = username; 
     this.password = password; 

     props = new Properties(); 
     props.put("mail.smtp.host", "smtp.gmail.com"); 
     props.put("mail.smtp.socketFactory.port", "465"); 
     props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 
     props.put("mail.smtp.auth", "true"); 
     props.put("mail.smtp.port", "465"); 
    } 

    public void send(String subject, String text, String from, String to) 
    { 
     Session thisSession = Session.getInstance(props, new Authenticator() 
     { 
      public PasswordAuthentication getPasswordAuthentification() 
      { 
       return new PasswordAuthentication(SslGmailSender.this.username, password); 
      } 
     }); 
     try 
     { 
      MimeMessage message = new MimeMessage(thisSession); 
      message.setFrom(new InternetAddress(from)); 
      message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); 
      message.setSubject(subject); 
      message.setText(text); 

      Transport.send(message); 
      System.out.println("Yor e-mail has been sent."); 
     } 
     catch (MessagingException ex) 
     { 
      System.out.println("Uuups... something went wrong..."); 
      System.out.println(ex.getMessage()); 
      System.exit(2); 
     } 
    } 
}

我遇到过这样的问题，因为谷歌不会让你登录“不安全的应用程序”，除非你在你的账户上启用它。我得到它的唯一方法是使用OAuth2，即使ssl完全“安全”，我认为他们只是担心有人偷走了您的密码。这可能与......无关...... –

修复所有这些[常见JavaMail错误]（http://www.oracle.com/technetwork/java/javamail/faq/index.html#commonmistakes），并且很可能会解决您的问题。 –

我将代码发送给我的朋友，它可以工作，但他使用Windows和Linux。所以，这可能是操作系统的问题。 –

解决这样：

 

package sendmail; 

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

/** 
* Created by caesar-84 on 9/28/16. 
*/ 
public class SslSender 
{ 
    private String username; 
    private String password; 
    private Properties props; 
    private String smtpMailProvider; 
    final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory"; 

    public SslSender(String username, String password) 
    { 
     this.username = username; 
     this.password = password; 
     if (username.substring(username.indexOf("@") + 1, username.length()).equals("hotmail.com")) 
     this.smtpMailProvider = "smtp.live.com"; 
     else this.smtpMailProvider = "smtp." + username.substring(username.indexOf("@") + 1, username.length()); 

     props = System.getProperties(); 

     props.put("mail.smtp.user", username); 
     props.put("mail.smtp.host", smtpMailProvider); 
     props.put("mail.smtp.port", "465"); 
     props.put("mail.smtp.starttls.enable", "true"); 
     props.put("mail.smtp.auth", "true"); 
     props.put("mail.smtp.socketFactory.port", "465"); 
     props.put("mail.smtp.socketFactory.class", SSL_FACTORY); 
     props.put("mail.smtp.socketFactory.fallback", "false"); 
     props.put("mail.smtp.ssl.trust", smtpMailProvider); 


    } 

    public void send(String subject, String text, String from, String to) 
    { 
     Session thisSession = Session.getInstance(props, new Authenticator() 
     { 
      @Override 
      protected PasswordAuthentication getPasswordAuthentication() { 
       return new PasswordAuthentication(SslSender.this.username, SslSender.this.password); 
      } 
     }); 
     MimeMessage message = new MimeMessage(thisSession); 

     try 
     { 
      message.setFrom(new InternetAddress(from)); 
      message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); 
      message.setSubject(subject); 
      message.setText(text); 

      Transport transport = thisSession.getTransport(); 
      transport.connect(smtpMailProvider, username, password); 
      Transport.send(message); 
      System.out.println("Your e-mail has been sent."); 
     } 
     catch (MessagingException ex) 
     { 
      System.out.println("Uuups... something went wrong..."); 
      System.out.println(ex.getMessage()); 
      System.exit(2); 
     } 
    } 
}

PS。仍然不适用于Hotmail。
