以下は、メールを送信するための私のコードです:
import java.util.Properties;
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.Message.RecipientType;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
public class SendMail {
public void sendMail(String m_from,String m_to,String m_subject,String m_body){
try {
Session m_Session;
Message m_simpleMessage;
InternetAddress m_fromAddress;
InternetAddress m_toAddress;
Properties m_properties;
m_properties = new Properties();
m_properties.put("mail.smtp.host", "usdc2spam2.slingmedia.com");
m_properties.put("mail.smtp.socketFactory.port", "465");
m_properties.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
m_properties.put("mail.smtp.auth", "true");
m_properties.put("mail.smtp.port", "9000");
m_Session=Session.getDefaultInstance(m_properties,new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("aaaaa","bbbbb@1"); // username and the password
}
});
m_simpleMessage = new MimeMessage(m_Session);
m_fromAddress = new InternetAddress(m_from);
m_toAddress = new InternetAddress(m_to);
m_simpleMessage.setFrom(m_fromAddress);
m_simpleMessage.setRecipient(RecipientType.TO, m_toAddress);
m_simpleMessage.setSubject(m_subject);
m_simpleMessage.setContent(m_body, "text/html");
//m_simpleMessage.setContent(m_body,"text/plain");
Transport.send(m_simpleMessage);
} catch (MessagingException ex) {
ex.printStackTrace();
}
}
public static void main(String[] args) {
SendMail send_mail = new SendMail();
String empName = "xxxxx";
String title ="<b>Hi !"+empName+"</b>";
send_mail.sendMail("123erft@slingmedia.com", "abz@gmail.com", "Please apply for leave for the following dates", title+"<br>by<br><b>HR<b>");
}
}
しかし、コードを実行すると、次の例外が発生します。
javax.mail.MessagingException: Could not connect to SMTP host: usdc2spam2.slingmedia.com, port: 9000;
nested exception is:
