java - 发送失败异常: bad password

Question

这个问题已经从一个相当模糊的问题演变成了一个更加明确的问题。该代码来自 example by mkyong 。至少根据谷歌的说法，it's a bad password ，我已遵循他们的登录建议。当然，当我输入正确的密码时，我会得到相同的结果，下面的密码是一个虚拟的。无论密码如何，输出都是相同的。

输出:

由于您正在连接到 Gmail。使用这些属性

prop.put("mail.smtp.starttls.enable", "true"); 
prop.put("mail.smtp.host", host); 
prop.put("mail.smtp.user", from); 
prop.put("mail.smtp.password", pass); 
prop.put("mail.smtp.port", "465"); 
prop.put("mail.smtp.auth", "true");
