java - Java发送邮件时出错

Question

我有桌面应用程序，但在发送邮件 javax.mail.MessagingException 时遇到此错误:无法连接到 SMTP 主机:smtp.gmail.com，端口:587；嵌套异常是:java.net.ConnectException:连接被拒绝:连接

~code~

 String host="smtp.mail.yahoo.com";
Properties props = new Properties();

props.setProperty("mail.smtp.auth", "true");
props.setProperty("mail.smtp.host",host);   
props.put("mail.smtp.host", host);
props.put("mail.stmp.user", "abc@yahoo.ca");//User name
//To use TLS
 props.put("mail.smtp.auth", "true");
 props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.password", "mypassword"); //Password 
     props.put("mail.smtp.socketFactory.fallback", "false");
 Session session1 = Session.getDefaultInstance(props, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
    String username = "abc@yahoo.ca";
    String password = "mypassword";
   return new PasswordAuthentication(username, password);
 }
});



 MimeMessage msg = new MimeMessage(session1);
String from = "abc@yahoo.ca";
String subject = "Testing...";

 msg.setFrom(new InternetAddress(from));
msg.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(email));
msg.setSubject(subject);
Transport.send(msg);

Answer 1

YahooMail smtp port是 465 或 587

添加此:-

props.put("mail.smtp.port", "465");

或

props.put("mail.smtp.port", "587");
