我第一次尝试在java中使用SMTP。但也许它甚至无法登录发送测试邮件。
public void sendMail() throws AddressException {
final String username = "myusername@gmail.com";
final String password = "*******";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("from@gmail.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("to@gmail.com"));
message.setSubject("Subject");
message.setText("Just Test Mail");
Transport.send(message);
System.out.println("SENT!");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
我不知道这段代码有什么问题。它编译得很好,但是当我尝试发送邮件时,它只是给我以下调试信息:
