发送邮件时,我遇到了以下错误:
java.lang.RuntimeException: javax.mail.SendFailedException: Sending failed; nested exception is: class javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465, response: -1
以下是我的代码:
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("email", "password");
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("email"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(this.to));
message.setSubject("Testing");
message.setText("Hey, this is the testing email.");
Transport.send(message);
// ...
}
这个错误的原因是什么,如何解决这个问题?
