Java騰訊企業郵箱發送郵件

##Java通過騰訊企業郵箱發送郵件(多人發送)

1. 企業郵箱需要使用ssl

   private static String account = "企業郵箱賬戶";// 登入賬戶
    private static String password = "企業郵箱密碼";// 登入密碼
    private static String host = "smtp.exmail.qq.com";// 伺服器位址
    private static String port = "465";// 端口
    private static String protocol = "smtp";// 協定
    //初始化參數
    public static Session initProperties() {
        Properties properties = new Properties();
        properties.setProperty("mail.transport.protocol", protocol);
        properties.setProperty("mail.smtp.host", host);
        properties.setProperty("mail.smtp.port", port);
        // 使用smtp身份驗證
        properties.put("mail.smtp.auth", "true");
        // 使用SSL,企業郵箱必需 start
        // 開啟安全協定
        MailSSLSocketFactory mailSSLSocketFactory = null;
        try {
            mailSSLSocketFactory = new MailSSLSocketFactory();
            mailSSLSocketFactory.setTrustAllHosts(true);
        } catch (GeneralSecurityException e) {
            e.printStackTrace();
        }
        properties.put("mail.smtp.enable", "true");
        properties.put("mail.smtp.ssl.socketFactory", mailSSLSocketFactory);
        properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.put("mail.smtp.socketFactory.fallback", "false");
        properties.put("mail.smtp.socketFactory.port", port);
        Session session = Session.getDefaultInstance(properties, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(account, password);
            }
        });
        // 使用SSL,企業郵箱必需 end
        // TODO 顯示debug資訊 正式環境注釋掉
        session.setDebug(true);
        return session;
    }
    // @param sender 發件人别名
    // @param subject 郵件主題
    //@param content 郵件内容
    //@param receiverList 接收者清單,多個接收者之間用","隔開
    //@param fileSrc 附件位址
    public void send(String sender, String subject, String content, String receiverList, String fileSrc) {
        try {
            Session session = initProperties();
            MimeMessage mimeMessage = new MimeMessage(session);
            mimeMessage.setFrom(new InternetAddress(account, sender));// 發件人,可以設定發件人的别名
            // 收件人,多人接收
            InternetAddress[] internetAddressTo = new InternetAddress().parse(receiverList);
            mimeMessage.setRecipients(Message.RecipientType.TO, internetAddressTo);
            // 主題
            mimeMessage.setSubject(subject);
            // 時間
            mimeMessage.setSentDate(new Date());
            // 容器類 附件
            MimeMultipart mimeMultipart = new MimeMultipart();
            // 可以包裝文本,圖檔,附件
            MimeBodyPart bodyPart = new MimeBodyPart();
            // 設定内容
            bodyPart.setContent(content, "text/html; charset=UTF-8");
            mimeMultipart.addBodyPart(bodyPart);
            // 添加圖檔&附件
            bodyPart = new MimeBodyPart();
            bodyPart.attachFile(fileSrc);
            mimeMultipart.addBodyPart(bodyPart);
            mimeMessage.setContent(mimeMultipart);
            mimeMessage.saveChanges();
            Transport.send(mimeMessage);
        } catch (MessagingException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
