Java發送郵件失敗，與SMTP SMTP郵件

我已經編寫了發送郵件的java代碼，當我使用端口號587，並且仍然運行時沒有停止，當我使用端口465時，會發出異常。我使用Tomcat，而我不知道是否有配置。 Mail.javaJava發送郵件失敗，與SMTP SMTP郵件

public class Mail { 
     String to; 
     String from; 
     String message; 
     String subject; 
     String smtpServ; 
     //getter and setter 
     public int sendMail(){

public class SMTPAuthenticator extends javax.mail.Authenticator {

<textarea name="message" rows="8" cols="30">

<input type="submit" value="Send Mail" />

sendMail.jsp

<jsp:useBean id="mail" scope="session" class="mailing.Mail" />

此代碼正常工作。試試這個

public static void sendEmail(Email mail) { 

String host = "smtp.gmail.com"; 
String from = "YOUR_GMAIL_ID"; 
String pass = "YOUR_GMAIL_PASSWORD"; 
Properties props = System.getProperties(); 
props.put("mail.smtp.starttls.enable", "true"); // added this line 
props.put("mail.smtp.host", host); 
props.put("mail.smtp.user", from); 
props.put("mail.smtp.password", pass); 
props.put("mail.smtp.port", "587"); 
props.put("mail.smtp.auth", "true"); 

// Get the default Session object. 
Session session = Session.getDefaultInstance(props, null); 

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

    // Set sender 
    message.setFrom(new InternetAddress("Senders_EMail_Id")); 

    // Set recipient 
    message.addRecipient(Message.RecipientType.TO, new InternetAddress("RECIPIENT_EMAIL_ID")); 

    // Set Subject: header field 
    message.setSubject("SUBJECT"); 

    // set content and define type 
    message.setContent("CONTENT", "text/html; charset=utf-8"); 

    Transport transport = session.getTransport("smtp"); 
    transport.connect(host, from, pass); 
    transport.sendMessage(message, message.getAllRecipients()); 
    transport.close(); 
    } catch (MessagingException mex) { 
    System.out.println(mex.getLocalizedMessage()); 
}

}

gr8。古德聽說:) – 2013-05-10 04:59:21

在代碼中你有口456。這是行不通的。

是@Michal博雷克我的意思是465，它仍然不停地運行。 – ftning 2013-05-09 16:24:44

是端口487將無法正常工作

這裏有一個例子代碼

小號

tring host = "smtp.gmail.com"; 
     String from = "your gmail account"; 
     String pass = "your gmail password"; 
     Properties props = System.getProperties(); 
     props.put("mail.smtp.starttls.enable", "true"); // added this line 
     props.put("mail.smtp.host", host); 
     props.put("mail.smtp.user", from); 
     props.put("mail.smtp.password", pass); 
     props.put("mail.smtp.port", "587"); 
     props.put("mail.smtp.auth", "true"); 

     Session session = Session.getDefaultInstance(props, null); 
     MimeMessage message = new MimeMessage(session); 
     message.setFrom(new InternetAddress(from)); 
     InternetAddress toAddress = new InternetAddress(email); 
     message.addRecipient(Message.RecipientType.TO, toAddress); 

     message.setSubject("Subject of the message"); 
     message.setText("Text Of the Message"); 

     Transport transport = session.getTransport("smtp"); 
     transport.connect(host, from, pass); 
     transport.sendMessage(message, message.getAllRecipients()); 
     transport.close();
