我正在开发一个监控程序,它会定期发送电子邮件。 一切都很顺利,直到我试图让它成为一个可运行的罐子。 邮件部分在eclipse中正常工作,我可以发送电子邮件。但是只要我把它变成一个可运行的jar,程序就不会发送电子邮件。
我做错了什么?
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);
}
}
这是从eclipse运行时的eclipse控制台。 注意:最后关闭连接。 此代码发送电子邮件。

Hello you got a new mailQUIT
答案 0 :(得分:0)
我不确定这是否有效,只需尝试代码:
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;
}
}
