新年快乐！

我正在开发一个应用程序,用户只要发生特定触发器就会收到电子邮件.

这是我用来发送电子邮件的功能：

public static void sendEmail(String host,String port,String useSSL,String useTLS,String useAuth,String user,String password,String subject,String content,String type,String recipients)
            throws NoSuchProviderException,AddressException,MessagingException  {
        final Properties props = new Properties();
        props.setProperty("mail.transport.protocol","smtp");
        props.setProperty("mail.smtp.host",host);
        props.setProperty("mail.smtp.port",port);        
        if (useSSL != null && !useSSL.equals("false") && useSSL.equals("true")) {
            props.setProperty("mail.smtp.ssl.enable",useSSL);
            props.setProperty("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");
            props.setProperty("mail.smtp.socketFactory.port",port);

        }
        if (useTLS != null && !useTLS.equals("false") && useTLS.equals("true")) {
            props.setProperty("mail.smtp.starttls.enable",useTLS);
            props.setProperty("mail.smtp.socketFactory.fallback","true");
        }   
        props.setProperty("mail.smtp.auth",useAuth);
        props.setProperty("mail.from",user);  
        props.setProperty("mail.smtp.user",user);
        props.setProperty("mail.password",password);

        Session mailSession = Session.getDefaultInstance(props,new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(props.getProperty("mail.smtp.user"),props
                        .getProperty("mail.password"));
            }
        });   

        Transport transport = mailSession.getTransport();

        MimeMessage message = new MimeMessage(mailSession);
        message.setHeader("Subject",subject);
        message.setContent(content,type);

        StringTokenizer tokenizer = new StringTokenizer(recipients,";");
        while (tokenizer.hasMoreTokens()) {
            String recipient = tokenizer.nextToken();
            message.addRecipient(Message.RecipientType.TO,new InternetAddress(recipient));
        }

        transport.connect();
        transport.sendMessage(message,message.getRecipients(Message.RecipientType.TO));
        transport.close();

奇怪的是,每当我尝试使用main方法运行上述代码时,它都会成功发送SSL和TLS协议的电子邮件.

public static void main(String args[])
    {
        try {
            Notifier.sendEmail("smtp.gmail.com","587","false","true","sender_email@gmail.com","testpassword","CHECKING SETTINGS","CHECKING EMAIL FUNCTIONALITY","text/html","cc_email@gmail.com");
        } catch (Exception ex) {
            ex.printStackTrace();
        } 
    }

但每当我尝试通过我的Web应用程序运行相同的代码时它就会失败.

通过SSL发送它会引发此错误：

com.sun.mail.smtp.SMTPSendFailedException: 530-5.5.1 Authentication required. Learn more at
jvm 1    | 530 5.5.1  https://support.google.com/mail/answer/14257 f12sm88286300pat.20 - gsmtp
jvm 1    | 
jvm 1    |  at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:2057)

通过TLS发送会抛出此错误：

javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com,port: 587;
jvm 1    |   nested exception is:
jvm 1    |  javax.net.ssl.SSLException: Unrecognized SSL message,plaintext connection?
jvm 1    |  at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1934)

任何形式的帮助表示赞赏.

EDIT1：

这是前端的tpl文件
