Java邮箱自动发送邮件详解编程语言

Android开发中，当忘记密码需要找回密码的时候，很多情况都是向注册邮箱自动发送注册登录密码，自己写的一个自动发送邮件的java类，亲测可用。

直接贴代码：

    public class SendMail {   
       
        static int port = 25;//端口号   
        static String server = "smtp.163.com";// 邮件服务器mail.cpip.net.cn   
        static String from = "小明";// 发送者,显示的发件人名字   
        static String user = "[email protected]";// 发送者邮箱地址   
        static String password = "xxxxxx";// 密码   
       
        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();   
            }   
        }   
    }
