ユーザからユーザ名、パスワードを取得した後にメールを送信しようとしています。すべての電子メールは1つの電子メールアドレスに送信されます。Eclipseのパスとlibフォルダの両方にjavax.mail.jarファイルとjavax.activation.jarファイルを追加しました。ここに私のコードはJavaメールでメールを送信する
public class Email {
public String emailTo = "[email protected]";
public boolean sendMail(String emailFrom, String message, String usernme, String passwrd)
{
final String username = usernme;
final String password = passwrd;
boolean success = false;
Properties prop = new Properties();
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtps.ssl.enable", "true");
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "587");
Session sess = Session.getInstance(prop, new javax.mail.Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
Message mssg = new MimeMessage(sess);
try {
mssg.setFrom(new InternetAddress(username, ""+username));
mssg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(emailTo));
mssg.setSubject("Suggestions");
mssg.setContent(message, "text/html; charset=utf-8");
Transport.send(mssg);
success = true;
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return success;
}
}
で、今私は、次のエラー

を取得しますが、このエラーを取得するための任意のアイデアを持っていますか？
Properties prop = new Properties();
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtp.starttls.enable", "true");
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "587");
Session sess = Session.getInstance(prop, new javax.mail.Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(emailFrom, password);
}
});
Message mssg = new MimeMessage(sess);
try {
mssg.setFrom(new InternetAddress(""+emailFrom));
mssg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(emailTo));
mssg.setSubject("Suggestions");
mssg.setContent(message, "text/html; charset=utf-8");
Transport.send(mssg);
success = true;
を次のように私は上記のコードを編集したadavance
を更新し

を取得しますか？
を多分これ役立ちますhttp://stackoverflow.com/questions/10509699/must-issue-a-starttls-command-first – RubioRic
もで[Gmailの指示を参照してください。 JavaMail FAQ]（http://www.oracle.com/technetwork/java/javamail/faq/index.html#gmail）を参照してください。 –
'prop.put（" mail.smtps.ssl.enable "、" true "）という行に誤字があります。 - 'smtp'の後ろに余分な 's'があります。 –
