问题 I believe for Register-ScheduledTask you can specify -User "System" or do something like: $principal = New-ScheduledTaskPrincipal -UserId SYSTEM -LogonType ServiceAccount -RunLevel Highest How do I do this with Register-ScheduledJob ? This command will be running the context of the local admin so it will have access to do this. I just don't see this option in the cmdlet. Here is an example of how to do this with the scheduled tasks cmdlet edit: Does windows make this impossible by design? If

问题 I am trying to create a periodic task for an asyncio event loop as shown below, however I am getting a "RuntimeError: cannot reuse already awaited coroutine" exception. Apparently, asyncio does not allow for the same awaitable function to be awaited as discussed in this bug thread.

I think the problem is that the "Start-Job" can not work with the task schedule together. Do you know how to

问题 If i want a method to repeat async, can i use @Scheduled and @Async together ? @Async @Scheduled(fixedDelay = x) public void doSomethingEveryXMinuteAsync() { // action } or is there another standard way to achive this ? 回答1: There is no need to use @Async. Just use fixedRate attribute of @Scheduled instead of fixedDelay. Spring will make another invocation on the method after the given time regardless of any call is already being processed. UPDATE: Apparently fixedRate attribute does not
