无法使用JavaMail API发送邮件 [英] Unable to send a mail using JavaMail api
问题描述
我正在尝试使用以下代码来发送邮件:-
I'm trying to sned a mail using the below code :-
java.awt.EventQueue.invokeLater(
new Runnable() {
@Override
public void run() {
new SwingWorker<Void, Integer>() {
String to = "xx@gmail.com";
// Sender's email ID needs to be mentioned
String from = "xexx@gmail.com";
// Assuming you are sending email from localhost
String host = "localhost";
// Get system properties
// Properties properties = System.getProperties();
// Setup mail server
protected Void doInBackground() throws Exception {
try {
Properties properties = new Properties();
properties.put("mail.smtp.socketFactory.port", "465");
properties.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
properties.put("mail.smtp.starttls.enable", "true");
// Get the default Session object.
Session session = Session.getDefaultInstance(properties);
// 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!");
// Now set the actual message
message.setText("Message" + jTextField1.getText() + " xx " + jTextField2.getText());
// Send message
Transport.send(message);
} catch (Exception x) {
x.printStackTrace();
}
return null;
}
protected void process() {
}
protected void done() {
try {
JOptionPane.showMessageDialog(null, "You'll get a response from our team shortly !");
} catch (Exception x) {
}
}
}.execute();
}
在调用上面的代码时,我得到一个异常:
On call of the above code i'm getting an Exception :

我该如何解决?
推荐答案
除非您在本地环境中运行邮件服务器,否则您将需要通过其他邮件属性指定一个:
Unless you are running a mail server on your local environment, then you are going to need to specify one via additional mail properties:
properties.put("mail.smtp.host", aHost);
例如,如果您使用的是Gmail中继,您将拥有:
As an example, if you were using the Gmail relay, you would have:
properties.put("mail.smtp.host", "smtp.gmail.com");
此外,您需要为会话设置mail.smtp.auth
属性.
In addition you need the mail.smtp.auth
property setup for the session.
properties.put("mail.smtp.auth", true);
取决于最终使用的主机,您可能还需要提供身份验证信息.例如,再次使用Gmail中继:
Depending on which host you end up using, you will probably also need to supply authentication information. For example, again with the Gmail relay:
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("someUserName", "somePassword");
}
}
);
