Java SSL电子邮件错误

我正在处理这个问题，并试图执行代码

其摘要如下：

    private static final String SSL_FACTORY = "SendMailDemoSSLSocketFactory"; //SendMailDemoSSLSocketFactory extends SSLSocketFactory       

    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.submitter", emailUsername);
    props.put("mail.smtp.user", emailUsername);
    props.put("mail.smtp.host", smtpHostName);
    props.put("mail.debug", debug);
    props.put("mail.smtp.port", smtpPort);
    props.put("mail.smtp.ssl.socketFactory.port", smtpPort);
    props.put("mail.smtp.ssl.socketFactory.class", SSL_FACTORY);
    props.put("mail.smtp.socketFactory.fallback", "true");
    props.put("mail.smtp.ssl.enable", "true");
    props.put("mail.smtp.starttls.enable", "true");
    props.setProperty("mail.smtps.ssl.enable", "true");
    props.put("mail.transport.protocol", "smtps");
    props.put("mail.smtp.ssl.trust", smtpHostName);

    Session session = Session.getDefaultInstance(props,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(emailUsername,
                            emailPassword);
                }
            });

    session.setDebug(Boolean.parseBoolean(debug));

    Message msg = new MimeMessage(session);
    //set message
    SMTPSSLTransport transport = (SMTPSSLTransport) session
            .getTransport("smtps");
    transport.connect(smtpHostName, new Integer(smtpPort).intValue(),
            emailUsername, emailPassword);
    msg.saveChanges();

    transport.sendMessage(msg, msg.getAllRecipients());

使用相同的方法，我能够成功地建立estb连接，但身份验证失败。我找不到代码哪里出错了

这是gmail smtp所需的唯一属性，我正在使用它： 在我的类路径中使用JAR：

• mail.jar
• 激活.jar
• additionnal.jar
• commons-io-2.4.jar

  String sendingHost = "smtp.gmail.com";
  int sendingPort =  465;
  Properties props = new Properties();
  props.put("mail.smtp.host", sendingHost);
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.port", sendingPort + "");
  /**ADD THIS**/
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.starttls.required", "true");
  
  props.put("mail.smtp.SSL", "true");
  props.put("mail.smtp.ehlo", "true");
  /**  **/
  
  Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
  protected PasswordAuthentication getPasswordAuthentication() {
  return new PasswordAuthentication(email.getFromAccount().getEmail(), email.getFromAccount().getPassword());
  }
  });

改为贴一张。没有人会为了重现你的问题而浏览整个教程。好的，谢谢！将立即编辑..FileNotFoundException中的文件是否存在？除此之外，“需要身份验证”消息很清楚。为什么不更轻松地使用它呢谢谢，但我正在做基于SSL的电子邮件发送程序。我可以使用smtp中继在未经授权的情况下发送电子邮件。现在，由于服务器是安全的，并且遵循现代安全标准，因此希望使服务更安全。@test：我修改了答案，添加新属性请尝试

String sendingHost = "smtp.gmail.com";
int sendingPort =  465;
Properties props = new Properties();
props.put("mail.smtp.host", sendingHost);
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", sendingPort + "");
/**ADD THIS**/
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.starttls.required", "true");

props.put("mail.smtp.SSL", "true");
props.put("mail.smtp.ehlo", "true");
/**  **/

Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(email.getFromAccount().getEmail(), email.getFromAccount().getPassword());
}
});
