获取“javax.mail.AuthenticationFailedException：连接失败”错误

我想做的事：发送一封与smtp.live.com主机发送的基本电子邮件，使用以下代码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 = "[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。

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

Answer 1

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。

需要的更改：相反，我必须使用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(); } } }
