How can we schedule task for 24 hours to get executed and store response in a variable for 24 hours?

Question

I am making post request to an api once in 24 hours and I want to store token received after post request in one variable which am using further.( Token value is valid for 24 hours) I want the same value for 24 hours. Please suggest me an efficient way of implementing this using springboot.

Answer 1

There are various ways you can accomplish this behaviour, but since you want to use Spring, I think you should declare a Bean which will store your token (in a volatile field), while also having a scheduled task for updating it every 24h. I mentioned using a Bean because you can then inject it into other services, so you don't have to resort to using a static field for sharing the value with other services.
