Java郵件可運行jar無法運行

Question

我正在開發一個監控程序，它會定期發送郵件。 每件事情都很好，直到我試圖使它成爲一個可運行的jar。 郵件部分在eclipse中正常工作，我可以發送電子郵件。但是，只要我使它成爲可運行的jar，程序就不會發送電子郵件。

我在做什麼錯？

package mailing; 
import java.util.*; 
import javax.mail.*; 
import javax.mail.internet.*; 
import javax.activation.*; 
public class TestEmail 
{ 
void addRecipients(Message.RecipientType type, Address[] addresses)throws MessagingException 
    { 

    } 
public static void main(String [] args) throws Exception 
    { 
     final int port = 465; 
     final String host = "smtp.gmail.com"; 
     final String from = "*****@gmail.com"; 
     final String to = "********@gmail.com"; 
     boolean auth = true; 
     final String username = "*******@gmail.com"; 
     final String password = "**********"; 

    boolean debug = true; 

    Properties props = new Properties(); 
    props.put("mail.smtp.host", host); 
    props.put("mail.smtp.port", port); 
    props.put("mail.transport.protocol", "smtp"); 
    props.put("mail.smtp.host","smtp.gmail.com"); 

    props.put("mail.smtp.socketFactory.port","465"); 
    props.put("mail.smtp.starttls.enable", "true"); 
    props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory"); 
    props.put("mail.smtp.auth","true"); 
    props.put("mail.smtp.port","465"); 

    Authenticator authenticator = null; 

     props.put("mail.smtp.auth", true); 
     authenticator = new Authenticator() { 
      PasswordAuthentication pa = new PasswordAuthentication(username, password); 
      @Override 
      public PasswordAuthentication getPasswordAuthentication() { 
       return pa; 
      } 

     }; 

    Session session = Session.getInstance(props, authenticator); 
    session.setDebug(debug); 


    MimeMessage message = new MimeMessage(session); 

     message.setFrom(new InternetAddress(from)); 
     InternetAddress[] address = {new InternetAddress(to.toString())}; 
     message.setRecipients(Message.RecipientType.TO, address); 
     String subject="- Job Alert -"; 
     message.setSubject(subject); 
     message.setSentDate(new Date()); 
     String body="Hello you got a new mail"; 
     message.setText(body); 
     Transport.send(message); 

    } 


} 

這是從eclipse運行時的eclipse控制檯。 注意：最後關閉連接。 此代碼發送電子郵件。

Hello you got a new mailQUIT 

Answer 1

我不知道這是否會工作，只是嘗試代碼：

public boolean sendMail(final String senderEmail, final String password, String recipientEmail, String ccEmail, String bccEmail) { 

    Properties props = System.getProperties(); 
    props.put("mail.smtp.starttls.enable", "true"); 
    props.put("mail.smtp.auth", "true"); 
    props.put("mail.smtp.host", "smtp.gmail.com"); 
    props.put("mail.smtp.port", "25"); 

    Session session = Session.getInstance(props, null); 

    try { 

     MimeMessage message = new MimeMessage(session); 
     message.setFrom(new InternetAddress(senderEmail)); 
     message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipientEmail)); 
     if (ccEmail.length() > 0) { 
      message.setRecipients(Message.RecipientType.CC, InternetAddress.parse(ccEmail)); 
     } 
     if(bccEmail.length() > 0){ 
      message.setRecipients(Message.RecipientType.BCC, InternetAddress.parse(bccEmail)); 
     } 
     message.setSubject(this.subject); 
     message.setSentDate(new Date()); 
     message.setText(this.textMessage, "utf-8"); 

     SMTPTransport t = (SMTPTransport) session.getTransport("smtps"); 

     t.connect("smtp.gmail.com", senderEmail, password); 
     t.sendMessage(message, message.getAllRecipients()); 
     t.close(); 

     System.out.println("Message sent successfully to '" + recipientEmail + "; " + ccEmail + "'."); 

     return true; 
    } catch (MessagingException e) { 
     System.out.println("Message not sent to '" + recipientEmail + "; " + ccEmail + "'."); 
     e.printStackTrace(); 
     return false; 
    } 
}
