Answer 1

如果您点击UnknownHostException：smtp.gmail.com，请尝试ping smtp.gmail.com并确保您获得了响应（能够访问）。通常，您的连接可能会被防火墙或代理阻止。否则您需要将javaee.jar和mail.jar放入类路径中。
干杯...

Answer 2

下载SMTP服务器服务器并转到链接 http://www.tutorialspoint.com/struts_2/struts_sending_email.html

Answer 3

请尝试使用此邮件属性。检查您的邮件是否应该成功发送。

Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "587");

使用struts在java中的网站电子邮件配置
