为什么JavaMail连接超时太长 [英] Why JavaMail connection timeout is too long

问题描述

在我的应用程序中，我连接到服务器以验证用户身份。这是代码：

In my application I connect to server to authenticate users. This is code:

try {
        Properties prop = new Properties();
        prop.put("mail.smtp.starttls.enable","true");
        prop.put("mail.smtp.auth", "true");
        prop.put("mail.smtp.connectiontimeout", 1000);


        Session session = Session.getInstance(prop, null);
        Transport transport = session.getTransport("smtp");
        transport.connect("mion.elka.pw.edu.pl", 587, registerLog, registerPass);
        transport.close();
        return true;
    } catch (NoSuchProviderException ex) {
        Logger.getLogger(RegisterController.class.getName()).log(Level.SEVERE, null, ex);
        return false;
    } catch(AuthenticationFailedException ex) {
        Logger.getLogger(RegisterController.class.getName()).log(Level.SEVERE, null, ex);
        return false;
    } catch (MessagingException ex) {
        Logger.getLogger(RegisterController.class.getName()).log(Level.SEVERE, null, ex);
        return false;
    }

我将连接超时设置为1000 ms = 1s但忽略它。当我调试并设置错误的用户名和密码时，我会抓住

I set connection timeout to 1000 ms = 1s but it's ignore. When i debug and set wrong username and password i catch

javax.mail.MessagingException: java.net.SocketTimeoutException: Read timed out

不是在1000毫秒之后，而是在5000 * 60毫秒= 5分钟之后

not after 1000 ms, but after 5000*60 ms = 5 min

有什么问题？我如何减少时间？

What is wrong ? How can i reduce timeoute ?

推荐答案
