无法在特定时间使用@Scheduled 发送邮件

Question

当我尝试使用调度程序发送邮件时，电子邮件在执行时触发，但未按计划触发。 预计它会在每周五下午 6:00 触发邮件。 在我的代码中，我将 @scheduler 中的 cronjob 设置为 // @Scheduled(cron = "0 0 18 ? 1/1 FRI#3 *") 和 // @Scheduled(cron = "0 0 18 ? 1/1 FRI#1 *")。

您的主机必须是 smtp.office365.com。 此外，您必须确保至少使用 TLSv1.2。

    final Properties config = new Properties();
    config.put("mail.smtp.auth", "true");
    config.put("mail.smtp.starttls.enable", "true");
    config.put("mail.smtp.starttls.required", "true");
    config.put("mail.smtp.ssl.protocols", "TLSv1.2");
    config.put("mail.smtp.port", "587");
    config.put("mail.smtp.host", "smtp.office365.com");
