我想使用以下代码检查在Spring MVC中是基于本地还是服务器发送电子邮件，这可能吗？

@Before("execution(public * org.springframework.mail.javamail.JavaMailSenderImpl.send(..))")
public void checkIfSendEmail(JoinPoint joinPoint) throws MailException {
    String appName = preferences.getStringValue("GENERAL","APPLICATION-NAME");
    if (!appName.toUpperCase().contains("DEV")) {
        joinPoint.getSignature().getName();
    }
    else {
        System.out.println("Not send email on local.");
    }
}
