Answer 1

我在使用旧版本的javax时遇到了这个错误。邮件（1.3.1）。当我切换到更高版本（1.4.4）时，问题消失了。

如果您使用的是Eclipse，那么您可能需要查看项目正在使用的库的构建路径，不仅是您指定的外部库，还包括内置库，如JavaEE5等，其中可能包含该库的旧版本。

您可以通过在代码中调试以下语句来检查正在使用的库的确切版本：Session=Session。getInstance（…

它不会显示源代码，但会给你它使用的mail.jar的目录路径，你可以打开它查看版本（在MANIFEST文件中）。

Answer 2

如果在添加上述代码后错误仍然存在。请参考邮件。这是项目的一部分。可能是邮件。该项目的jar已损坏。使用最新版本的mail进行更改。罐和检查

Answer 3

我觉得你有问题。你的授权是空的。

Authenticator auth = new SMTPAuthenticator();

尝试

 Authenticator auth = new Authenticator()
    {
        @Override
        protected PasswordAuthentication getPasswordAuthentication()
        {
            return new PasswordAuthentication(SMTP_AUTH_USER, SMTP_AUTH_PWD);
        }
    };

这个代码对我有用。javax。邮件v1。5.

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Properties;
public class Main {
    public static void main(String[] args) {
        final String smtpAuthUserName = "[e-mail]";
        final String smtpAuthPassword = "YOUR_PASSWORD";
        String emailFrom = "EMAIL_FROM";
        String emailTo   = "EMAIL_TO";
        Authenticator authenticator = new Authenticator()
        {
            @Override
            protected PasswordAuthentication getPasswordAuthentication()
            {
                return new PasswordAuthentication(smtpAuthUserName, smtpAuthPassword);
            }
        };
        Properties properties = new Properties();
        properties.setProperty("mail.smtp.host", "smtp.office365.com");
        properties.setProperty("mail.smtp.port", "587");
        properties.setProperty("mail.smtp.auth", "true");
        properties.setProperty("mail.smtp.starttls.enable", "true");
        Session session = Session.getInstance( properties, authenticator );
        try
        {
            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(emailFrom));
            InternetAddress[] to = {new InternetAddress(emailTo)};
            message.setRecipients(Message.RecipientType.TO, to);
            message.setSubject("PLACE_SUBJECT_HERE");
            message.setText("YOUR_MESSAGE_HERE");
            Transport.send(message);
        }
        catch (MessagingException exception)
        {
            exception.printStackTrace();
        }
    }
}
