使用Java Mail API。 javax.mail.MessagingException：无法确定本地电子邮件地址异常[重复]

Question

这个问题在这里已有答案：

• Failed messages: javax.mail.MessagingException: can't determine local email address 1回答

我正在使用java邮件API并且它在本地计算机上运行良好但是当我在服务器上部署我的web应用程序时，我得到一个例外，说javax.mail.MessagingException：无法确定本地电子邮件地址。

这是我的代码

Properties 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");

    try {
    Session session = Session.getInstance(props, new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("[email protected]", "fromEmailPass");
        }
    });

        MimeMessage message = new MimeMessage(session);
        message.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
        message.setSubject("sub");
        message.setText("msg");    
        Transport.send(message);

        System.out.println("mail sent successfully");
    } catch (Exception e) {
        e.printStackTrace();
        throw new RuntimeException(e);

    }

下面给出的是此代码抛出的异常。

javax.mail.MessagingException：无法确定本地电子邮件地址

Answer 1

从这个问题：Failed messages: javax.mail.MessagingException: can't determine local email address

作者似乎建议在未设置发件人地址时抛出此异常。

MimeMessage message = new MimeMessage(session);
message.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
message.setFrom("[email protected]"); // <-- add 'from' email address
message.setSubject("sub");
message.setText("msg");    
Transport.send(message);

Answer 2

消息显示“缺少本地电子邮件地址”，这意味着发件人的电子邮件地址丢失。我想你可以尝试这样做：

JavaMailSenderImpl sender = new JavaMailSenderImpl();
sender.setHost("mail.host.com")

MimeMessage message = sender.createMimeMessage();

MimeMessageHelper helper = new MimeMessageHelper(message);
helper.setFrom("[email protected]");
helper.setTo("[email protected]");
helper.setText("testing text");
