Unable to design a solution

I am new to Java world. Here is my scenario:

I have to keep checking for a creation of a file of certain format say <file-name>.ppt in predefined directory. And it has to happen continuously. Once it gets created then I have to update the status in a table. Updating in a table is fine. But I don't know what is the good way to keep checking in a path for this file. The requirement is to check for the file existence continuously for 1 hour with 30 seconds of interval. Once it gets created within that time, then it is fine (where I update the table with 'COMPLETED' status). Else, it is a time out (and I will update same table with 'FAILURE').

I request forum veterans here to guide me to proceed with good way to achieve this.

I am on Java 8 and using SpringBoot

Take a look at A Guide to WatchService by baeldung and see if it helps.

I would also consider whether Spring Boot is needed for such a small application. I propose not.

This requirement is part of bigger application. I am just handling one of the many requirements. I just told what I am using so that experts offering solutions will know what I am using.

Definitely consider Ron's suggestion before trying to roll your own solution which is probably going to be inferior to WatchService.

Oh yea I second what Junilu says. Definitely do not try and implement your own solution when you have utilities built in such as WatchService.

Thanks for guiding me in the right direction. I am considering this.
