com.sun.mail.smtp.SMTPSendFailedException：530 5.7.0必须首先发出STARTTLS命令

我在play 2.2.1中创建了一个应用程序并试图向其添加电子邮件功能。为此，我在build.sbt中添加了依赖项file.But得到一个例外下面com.sun.mail.smtp.SMTPSendFailedException：530 5.7.0必须首先发出STARTTLS命令

我的代码

 String smtpHost = Play.application().configuration().getString("smtp.host"); 
     Integer smtpPort = Play.application().configuration().getInt("smtp.port"); 
     String smtpUser = Play.application().configuration().getString("smtp.user"); 
     String smtpPassword = Play.application().configuration().getString("smtp.password"); 

     Email mail = new SimpleEmail(); 
     try { 
      mail.setFrom("[email protected]"); 
      mail.setSubject("hi"); 
      mail.setMsg("This is the message"); 
      mail.addTo("[email protected]"); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 



     mail.setHostName(smtpHost); 
     if (smtpPort != null && smtpPort > 1 && smtpPort < 65536) { 
      mail.setSmtpPort(smtpPort); 

     } 
     if (!smtpUser.isEmpty()) { 
      mail.setAuthentication(smtpUser, smtpPassword); 
     } 


     try { 
      mail.send(); 
     } catch (Exception e) { 
      e.printStackTrace(); 

    }

包含的代码解释application.conf

# Email Configuration 
smtp.host=smtp.gmail.com 
smtp.port=587 
smtp.ssl=yes 
smtp.user="[email protected]" 
smtp.password="123456" 
smtp.auth=true 
smtp.STARTTLS.enable=true

但我得到一个异常
