Java实现邮件发送

发送邮件可与使用java提供的mail.jar实现。

public class EmailUtils {    private static String fromEmail="你的邮箱";//发件邮箱    private static String sqm="授权码";//授权码，切记只能是第三方授权码，不要用密码    private static String host="smtp.163.com";//服务器地址    /**     * 参数说明：     * 1、接收人的邮箱     * 2、接收人姓名     * 3、要发送的消息     * @throws MessagingException      * @throws UnsupportedEncodingException      * @throws UnknownHostException */    public static void sendEmail(String toEmail,String name,String msg)  {        Properties properties=new Properties();        properties.setProperty("mail.transport.protocol", "smtp");//设置邮箱协议        properties.setProperty("mail.smtp.host", host);//设置邮箱的服务器地址        properties.setProperty("mail.smtp.auth", "true");//设置是否请求认证        //获取会话对象---连接邮箱服务器        Session session=Session.getInstance(properties);        session.setDebug(true);//开启调试信息        //创建消息对象        try {            MimeMessage message=new MimeMessage(session);            //设置消息信息            message.setFrom(new InternetAddress(fromEmail, "发件人","UTF-8"));//设置发件人信息            message.setRecipient(MimeMessage.RecipientType.TO,                     new InternetAddress(toEmail, name, "utf-8"));            message.setSubject("标题");            message.setContent(msg,                    "text/html;charset=utf-8");            message.setSentDate(Calendar.getInstance().getTime());//设置发送时间            //获取传输对象            Transport transport=session.getTransport();            //登录            transport.connect(fromEmail, sqm);            //发送邮件    transport.sendMessage(message,message.getAllRecipients());            //关闭            transport.close();        } catch (Exception e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
