我有一個HTML表單，用戶可以在其中輸入多個郵件ID，但我不知道如何將郵件發送給多個人我成功地向一個用戶發送郵件，但在這里我被困在發送多封電子郵件中。我做了什么：這是我的類：EmailUntilitypublic class EmailUtility {public static void sendEmail(String host, String port, final String userName, final String password,        String toAddress, String subject, String message) throws AddressException, MessagingException {    Properties properties = new Properties();    properties.put("mail.smtp.host", host);    properties.put("mail.smtp.port", port);    properties.put("mail.smtp.auth", "true");    properties.put("mail.smtp.starttls.enable", "true");    Session session = Session.getDefaultInstance(properties, new javax.mail.Authenticator() {        protected PasswordAuthentication getPasswordAuthentication() {            return new PasswordAuthentication(userName, password);        }    });    session.setDebug(false);    Message msg = new MimeMessage(session);    msg.setFrom(new InternetAddress(userName));    InternetAddress[] toAddresses = { new InternetAddress(toAddress) };    msg.setRecipients(Message.RecipientType.TO, toAddresses);    msg.setSubject(subject);    msg.setSentDate(new Date());    msg.setText(message);    Transport.send(msg);}}這個是我的Servlet doPost        String recipient = request.getParameter("email-ids");    String subject = request.getParameter("subject");    String content = request.getParameter("content");    System.out.println(recipient);    try {        EmailUtility.sendEmail(host, port, user, pass, recipient, subject,                content);    } catch (Exception ex) {        ex.printStackTrace();當我在控制臺上打印時，我從UI獲取郵件ID，因為所有這三個都帶有分離器[email protected],[email protected],[email protected],當只有一個收件人時，這個工作正常，但是當有多個收件人時，我不知道該怎么做我正在使用 API 發送郵件。java.mail
