Question

我正在尝试使用servlet发送邮件，但尝试发送时出现异常：

Exception is :: java.lang.SecurityException

相关代码：

Properties props = new Properties();  
  props.put("mail.smtp.host", "smtp.gmail.com");  
  props.put("mail.smtp.socketFactory.port", "465");  
  props.put("mail.smtp.socketFactory.class",  
            "javax.net.ssl.SSLSocketFactory");  
  props.put("mail.smtp.auth", "true");  
  props.put("mail.smtp.port", "465");     
  **Session session = Session.getDefaultInstance(props,  
   new javax.mail.Authenticator()** {  
   protected PasswordAuthentication getPasswordAuthentication() {  
   return new PasswordAuthentication("gmailid","password");//change accordingly

代码在粗线上给出例外.Plz提供任何解决方案以尽快解决该问题。

Answer 1

将端口更改为587。
我猜错了，这是Google的安全政策避免对指定帐户进行任何编程访问。

登录您需要发送邮件的Gmail帐户打开这个链接：
```
https://www.google.com/settings/security/lesssecureapps
```
在此页面上，开启Access for less secure apps然后尝试试。
