我需要使用Gmail作爲SMTP服務器從我的應用程序發送電子郵件。 這是我的郵件連接器類和我在一個單獨的屬性文件中設置的值MailConnectException：無法連接到主機，端口：smtp.gmail.com，465; timeout -1
public class EmailConnector {
public static Session sessionCreate() {
final String fromEmail = ConfigurationManager.getInstance().getProperty(EmailConfig.SENDER_EMAIL.toString());
final String password = ConfigurationManager.getInstance().getProperty(EmailConfig.SENDER_PASSWORD.toString());
Properties props = new Properties();
props.put("mail.smtp.host", ConfigurationManager.getInstance().getProperty(EmailConfig.SMTP_HOST.toString()));
props.put("mail.smtp.socketFactory.port",
ConfigurationManager.getInstance().getProperty(EmailConfig.SSL_PORT.toString()));
props.put("mail.smtp.socketFactory.class",
ConfigurationManager.getInstance().getProperty(EmailConfig.SSL_FACTORY_CLASS.toString()));
props.put("mail.smtp.auth",
ConfigurationManager.getInstance().getProperty(EmailConfig.SMTP_AUTHENTICATION.toString()));
props.put("mail.smtp.port", ConfigurationManager.getInstance().getProperty(EmailConfig.SMTP_PORT.toString()));
Authenticator auth = new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(fromEmail, password);
}
};
return Session.getDefaultInstance(props, auth);
}
}
屬性：
#Email send configuration
SENDER_EMAIL = [email protected]
SENDER_PASSWORD = abcalert321
SMTP_HOST = smtp.gmail.com
SSL_PORT = 465
SMTP_AUTHENTICATION = true
SMTP_PORT = 465
SSL_FACTORY_CLASS = javax.net.ssl.SSLSocketFactory
然後，我實現了一個郵件發送者類，稱爲「GroupEmail.class」
public class GroupEmail {
public void sendEmail() throws IOException {
String recipient = "[email protected]";
Session session = EmailConnector.sessionCreate();
/* subject of email */
String emailSubject = "ABC_Alert";
try {
MimeMessage msg = new MimeMessage(session);
msg.addHeader("Content-type", "text/HTML; charset=UTF-8");
msg.addHeader("format", "flowed");
msg.addHeader("Content-Transfer-Encoding", "8bit");
msg.setFrom(new InternetAddress("[email protected]", "ABC Alerts"));
msg.setReplyTo(InternetAddress.parse("[email protected]"));
msg.setSubject(emailSubject, "UTF-8");
msg.setSentDate(new Date());
/* buyer email address */
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipient));
/* Create the message body part */
msg.setText("A new Test-Alert from AB_Alerts");
/* Send message */
Transport.send(msg, "[email protected]", "abcalert321");
} catch (MessagingException | UnsupportedEncodingException e) {
SystemLogger.logErrorMessege(this, e);
}
}
}
畢竟我在需要觸發郵件發送的地方調用「GroupEmail.class」。
GroupEmail groupEmail = new GroupEmail();
groupEmail.sendEmail();
我在本地主機上使用Tomcat v8服務器，當應用程序工作時，我得到了下面的異常。
98656 [http-nio-8080-exec-9] ERROR it.codegen.rnd.cgalert.notification.template.email.GroupEmail - Couldn't connect to host, port: smtp.gmail.com, 465; timeout -1
