下载第三方 jar包

javamail-1.4.7

在button的click事件中加入代码:

Properties props=new Properties();props.put("mail.smtp.host", "smtp.163.com");props.put("mail.smtp.socketFactory.port", "465");props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");props.put("mail.smtp.auth","true");props.put("mail.smtp.port","465");Session session=Session.getDefaultInstance(props,new javax.mail.Authenticator(){protected javax.mail.PasswordAuthentication getPasswordAuthentication(){return new javax.mail.PasswordAuthentication("me@163.com", "password");}});try{Message message=new MimeMessage(session);message.setFrom(new InternetAddress("me@163.com"));message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("To@gmail.com"));message.setSubject("hi this is javamail");message.setText("hi javaemail");Transport.send(message);JOptionPane.showMessageDialog(null, "message sent");}catch (Exception e) {JOptionPane.showMessageDialog(null, e);}
