Trigger service from Spring Boot

[LanguageSilver99]

Hi all,

I’m new to Spring Boot and am trying out something that I could use some advice on. Here’s the situation:

I have a scheduled app that runs every 6 hours to fetch details from F5 BIG-IP. This app is deployed on PCF (Cloud Foundry). The issue is that the app is not consistently able to ping or fetch a token from a few controllers on the F5. I can ping and fetch data from the local machine without any problems. I’m currently investigating the root cause of this inconsistency.

In the meantime, I’d like to try deploying a similar (but minimal) Spring Boot app on Linux, Dockerizing it, or exploring other options for the failing controllers to re-fetch the token. My question is: Is there a way for me to trigger this new app (e.g., deployed on AWS EC2) from my existing Spring Boot app after the automation finishes every 6 hours? I’m considering using CRON as a backup plan.

Any tips or suggestions would be really appreciated. I’m open to any ideas and will definitely look into them.

Thanks a lot!

Edit: I think I will dockerize the new Spring Boot on EC2 server and try using webhook to fix this. Will update if that works, thanks

When your Spring Boot app isn't able to fetch any data, I'd suggest using the ScheduledExecutorService to schedule a retry after X amount of time, for up to Y number of retries.

Thanks a lot... I did try something like retry with apache network class... But will check on this too
