代码如下：

 public class MailUtil {
    public static void main(String args[]) {
        JavaMailSenderImpl senderImpl = new JavaMailSenderImpl();
        // 设定mail server
        senderImpl.setHost("smtp.qq.com");
        senderImpl.setProtocol("smtp");
        senderImpl.setUsername("[e-mail]");
        senderImpl.setPassword("xxxxxxxxx");
        senderImpl.setPort(465);
        senderImpl.setDefaultEncoding("UTF-8");

        // 建立邮件消息
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        // 设置收件人，寄件人 用数组发送多个邮件
        String[] array = new String[] {"[e-mail]","[e-mail]"};
        mailMessage.setTo(array);
        mailMessage.setFrom("[e-mail]");

        mailMessage.setSubject("测试简单文本邮件发送！");
        mailMessage.setText("测试我的简单邮件发送机制！！");

        Properties prop = new Properties();
        prop.put("mail.smtp.auth", "true");
        prop.put("mail.smtp.timeout", "25000");
        senderImpl.setJavaMailProperties(prop);
        // 发送邮件
        senderImpl.send(mailMessage);

        System.out.println(" 邮件发送成功.. ");
    }
}

自己回复我改用587端口就成功了

 senderImpl.setPort(587);//587/465
