scheduled-tasks

问题 I am writing a Scheduling application, and each row in my Database Table is a different task to run at a certain time. In my application, I pull this information, and store each task in a separate object, and keep them stored in a List. As of right now, when I run my function to refresh this, there are no checks and it just adds them all again. I need to figure out the best way to see if an object already exists for the particular job, and only create a new Object for it if it doesn't. Would

问题 I have service which is not invoked by user request, but by task.

问题 I've recently migrated from using Gulp 3 to Gulp 4. Introducing the new tasks like gulp.src() and gulp.parallel() adds more flexibility and ease of use. Here is my code attempting to execute tasks in series. Asynchronous task which creates files dynamically let css_purge_libs = async () => { var pacs = ["!bootstrap", "bulma", "animate.css"]; var paths = await fetch_resources(pacs, "bower", "css|sass"); return gulp.src(paths) .pipe(before(true, config.css.destination.temp + "/lib")()) .pipe(P

问题 I'm trying to setup schedule for my commands in /app/Console/Kernel.php and found out that withoutOverlapping() doesnt work with runInBackground() This works without overlaps: $schedule ->command('test:update') ->withoutOverlapping(); This overlaps tasks: $schedule ->command('test:update') ->withoutOverlapping() ->runInBackground(); 回答1: In the first case, it was working without overlaps because command was running in the foreground and scheduler was busy processing this command thus didn't

问题 I'm trying to use Powershell to get the NextRunTime for some scheduled tasks. I'm retrieving the values but they don't match up to what I'm seeing in the Task Scheduler Management Console. For example, in the Task Scheduler console my "TestTask" has a Next Run Time value of "1/9/2018 12:52: 30 PM". But when I do the following call in Powershell it shows "12:52: 52 PM" for the NextRunTime. Get-ScheduledTask -TaskName "TestTask" | Get-ScheduledTaskInfo From what I've seen the seconds value is

问题 I have following annotation in my code @Scheduled(fixedDelayString = "${app.delay}") At this case I have to have properties like this app.delay=10000 #10 sec Propery file looks unreadable because I have calculate value to miliseconds. Is there way to pass value like 5m or 30s there ? 回答1: As far as I know, you can't do it directly. However, Spring boot configuration properties do support automatic conversion of parameters like 15s and 5m to Duration . This means you could create a

问题 I've set up a non-repeating task which is triggered by workstation unlock. How can I condition it so that only runs within a specific period of time during the day? For example just between 8-10 A.M? There's a similar question answered before but that solution can only be used for a repeating task. 回答1: I was hoping for an answer, came back and there was nothing but since I needed one badly enough I found it myself. This process always amazes me. You need to do your task via a batch file
