MailConnectException：嵌套异常：java.net.SocketException：权限被拒绝：connect

Question

我试图使用此示例将邮件从gmail ID发送到另一个。 这是我的文件：

public class SendHTMLEmail

  // Recipient's email ID needs to be mentioned.
  String to = "harsh.hr99@gmail.com";

  // Sender's email ID needs to be mentioned
  String from = "web@gmail.com";

  // Assuming you are sending email from localhost
  String host = "localhost";

  // Get system properties
  Properties properties = System.getProperties();

  // Setup mail server
  properties.setProperty("mail.smtp.host", host);
  properties.setProperty("mail.user", "Admin");
  properties.setProperty("mail.password", "admin");

  // Get the default Session object.
  Session session = Session.getDefaultInstance(properties);

  try{
     // Create a default MimeMessage object.
     MimeMessage message = new MimeMessage(session);

     // Set From: header field of the header.
     message.setFrom(new InternetAddress(from));

     // Set To: header field of the header.
     message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));

     // Set Subject: header field
     message.setSubject("This is the Subject Line!");

     // Send the actual HTML message, as big as you like
     message.setContent("<h1>This is actual message</h1>", "text/html" );

     // Send message
     Transport.send(message);
     System.out.println("Sent message successfully....");
  }catch (MessagingException mex) {
     mex.printStackTrace();
  }

我在localhost：9091端口上运行Tomcat服务器。 我收到以下错误：

我该如何解决？

好吧，您设置“ host = localhost”，这样您的程序将尝试使用位于localhost的smtp服务器。 问题是：您没有（也不想）在本地主机上安装了smtp服务器。 至少看起来是这样。

我认为您想做的是： http : //www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/

如果尝试此示例，则需要记住不要发布它，因为它包含硬编码的Gmail凭据。
