非常簡單的發送郵件實現，網上有很多啦，但還是自己寫寫記錄下吧。

package cn.jmail.test; import java.util.PRoperties; import javax.mail.*;import javax.mail.internet.*; public class FirstMail {    /**     * 發送簡單郵件方法     * @param host    發送郵件服務器的ip     * @param from    發送人地址     * @param to    接收人地址     * @param subject    郵件主題     * @param text    內容     * @param senderUsername    發送人的賬戶     * @param senderPassWord    發送人的密碼     * mail.smtp.auth 是否需要身份驗證 一般都是需要的     */    public static void sendMail(String host, String from, String to, String subject, String text,             final String senderUsername, final String senderPassword){        Properties props = System.getProperties();        props.put("mail.smtp.host", host);        props.put("mail.smtp.auth", "true");        session session = Session.getDefaultInstance(props, new Authenticator() {            @Override            public PasswordAuthentication getPasswordAuthentication(){                return new PasswordAuthentication(senderUsername, senderPassword);            }        });        try {            MimeMessage message = new MimeMessage(session);            message.setFrom(new InternetAddress(from));            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));            message.setSubject(subject);            message.setText(text);            Transport.send(message);        } catch (AddressException e) {            e.printStackTrace();        } catch (MessagingException e) {            e.printStackTrace();        }    }         public static void main(String[] args) {        String host = "smtp.163.com";        String from = "xxxxxx@163.com";        String to = "xxxxxxxx@QQ.com";        String subject = "Hello, this is a test email.";        String text = "Hello,LiLei.";         String senderUsername = "xxxxxx@163.com";        String senderPassword = "xxxxxx";        FirstMail.sendMail(host, from, to, subject, text, senderUsername, senderPassword);    }}
