私は以下のコードのようなコードを使用していますuseridusernameusername and passwordは、メールを送信する場所からのメールのパスワードを示します
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.setProperty("mail.transport.protocol", "smtps");
props.put("mail.smtp.user", userid);
props.put("mail.smtp.password", password);
props.put("mail.smtp.port", "465");
props.put("mail.smtps.auth", "true");
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
InternetAddress fromAddress = null;
InternetAddress toAddress = null;
try {
fromAddress = new InternetAddress(from);
toAddress = new InternetAddress(to);
} catch (AddressException e) {
e.printStackTrace();
}
message.setFrom(fromAddress);
message.setRecipient(RecipientType.TO, toAddress);
message.setSubject(subject);
message.setText(text);
//SMTPSSLTransport transport =(SMTPSSLTransport)session.getTransport("smtps");
Transport transport = session.getTransport("smtps");
transport.connect(host, userid, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
しかし、それは私に次のようなエラーを与えています
javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 465;
nested exception is:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1972)
at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:642)
誰かが私のコードの問題を私に提案できますか.....事前にuに感謝します.....
