        this.javaMailSender = javaMailSender;

    SimpleMailMessage send()
    {
        SimpleMailMessage mailMessage = new SimpleMailMessage();
        mailMessage.setTo("abc@gmail.com");
        //mailMessage.setReplyTo("someone@localhost");
        mailMessage.setFrom("xyz@gmail.com");
        mailMessage.setSubject("Lorem ipsum");
        mailMessage.setText("Lorem ipsum dolor sit amet [...]");
        javaMailSender.send(mailMessage);
        return mailMessage;
    }
}

我创建了REST端点，在访问 http://localhost:8080/send-mail 后运行apache服务器后，我得到 HTTP状态404 - /发送邮件
