我試圖發送郵件使用SMTP,它設置爲具有25,587個端口和TLS的默認SMTP服務器。 MS Exchange 2010.所有身份驗證數據都是正確的,因爲我可以通過郵件的Web界面登錄。下面的代碼不使用Gmail的SMTP服務器工作,但是當我用我自己的SMTP服務器,它拋出我的證書路徑錯誤:TLS SMTP郵件Java引發SSLHandShakeException
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException:PKIX路徑建築失敗: sun.security.provider.certpath.SunCertPathBuilderException:無法找到 有效證明路徑請求的目標
public static void SendMailTLS(String to, String subject, String body) throws Exception{
try {
java.util.Properties props = new java.util.Properties();
props.put("mail.smtp.host", "sample");
props.put("mail.smtp.port", "587");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.connectiontimeout", "10000");
final String EmailUser = "sample";
final String EmailPassword = "sample";
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(
EmailUser,EmailPassword);
}
}); session.setDebug(true);
InternetAddress fromAddress = new InternetAddress("sample",
"sample");
InternetAddress toAddress = new InternetAddress("sample",
"sample");
Message msg = new MimeMessage(session);
msg.setFrom(fromAddress);
msg.addRecipient(Message.RecipientType.TO,toAddress);
msg.setSubject(subject);
msg.setText(body);
Transport transport = session.getTransport("smtp");
transport.connect();
transport.sendMessage(msg, msg.getAllRecipients());
} catch (MessagingException e) {e.printStackTrace();}
}
難道我做錯了什麼?
