如何编写一个cron表达式，它每5分钟运行一次，从工作日的9:30到4:00 (春季/java)？

Question

我有一个Spring Boot应用程序，它有一个作业的cron表达式，我想每5分钟在星期一到星期五上午9:30到下午4:00运行它。

但是看起来cron表达式不正确。

application.properties

job.signal.cron=0 0/5 9:30-16 * * MON-FRI

启动时错误：

Caused by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'findSignal': For input string: "9:30" '9:30-16' in cron expression "0 0/5 9:30-16 * * MON-FRI"
