无法使用Javamail通过SSL或TLS使用SMTP发送邮件

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", "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

Host:
     

         
Port:
         

         

                
                    Enable SSL?
         
         

                
                    Enable TLS?
         
         

                
                    Enable Authentication?
         
            
     
User:
     

     
Password:
     

     
Recipient(s):
     

值将保存在配置文件中,如下所示:

host=smtp.gmail.com
port=587
ssl=false
tls=true
auth=true
user=send_user_email@gmail.com
password=O0UbYboDfVFRaiA=
recipients=cc_user_email@gmail.com
trigger1=false
attempt=0
trigger2=false
percent=5
anyOrAll=ANY
trigger3=true
format=HTML
trigger4=true
trigger5=true

EDIT2:

public static void sendEmail(String message)
      throws NoSuchProviderException, AddressException, MessagingException
  {
    if (message == null || message.trim().equals("")) return;

    StringBuffer content = new StringBuffer();
    content.append(getHeader());
    content.append(message);
    content.append(getFooter());
    String format = NotifyProps.getFormat();
    String type = "text/plain";
    if (format.equals(NotifyProps.HTML)) type = "text/html";

    sendEmail(NotifyProps.getHost(), NotifyProps.getPort(), Boolean.toString(NotifyProps.getUseAuth()), Boolean.toString(NotifyProps.getUseSSL()), Boolean.toString(NotifyProps.getUseTLS()),NotifyProps.getUser(), NotifyProps.getPassword(),
              "Transaction Processor Auto Notification", content.toString(), type,
              NotifyProps.getRecipients())
  }

这是设置和获取属性的类:

谢谢.
