Java郵箱自動發送郵件

Android開發中，當忘記密碼需要找回密碼的時候，很多情況都是向注冊郵箱自動發送注冊登錄密碼，自己寫的一個自動發送郵件的java類，親測可用。

直接貼代碼：

    public class SendMail {


    static int port = 25;//端口號  
    static String server = "smtp.163.com";// 郵件服務器mail.cpip.net.cn  
    static String from = "小明";// 發送者,顯示的發件人名字  
    static String user = "xxxxx@163.com";// 發送者郵箱地址  
    static String password = "xxxxxx";// 密碼  

    public static void sendEmail(String email, String subject, String body)  
            throws UnsupportedEncodingException {  
        try {  
            Properties props = new Properties();  
            props.put("mail.smtp.host", server);  
            props.put("mail.smtp.port", String.valueOf(port));  
            props.put("mail.smtp.auth", "true");  
            Transport transport = null;  
            Session session = Session.getDefaultInstance(props, null);  
            transport = session.getTransport("smtp");  
            transport.connect(server, user, password);  
            MimeMessage msg = new MimeMessage(session);  
            msg.setSentDate(new Date());  
            InternetAddress fromAddress = new InternetAddress(user, from,  
                    "UTF-8");  
            msg.setFrom(fromAddress);  
            InternetAddress[] toAddress = new InternetAddress[1];  
            toAddress[0] = new InternetAddress(email);  
            msg.setRecipients(Message.RecipientType.TO, toAddress);  
            msg.setSubject(subject, "UTF-8");  
            msg.setText(body, "UTF-8");  
            msg.saveChanges();  
            transport.sendMessage(msg, msg.getAllRecipients());  
        } catch (NoSuchProviderException e) {  
            e.printStackTrace();  
        } catch (MessagingException e) {  
            e.printStackTrace();  
        }  
    }  
}  </pre>
