Executing controlled number of threads between a given time in java

I am having a list of requests in database. My application has to take the requests from DB and execute it in a thread. Only four threads can run at a time. Application should not process any requests before 9 AM and after 7 PM.

Could you please suggest the best way to implement this in java? Is Spring ThreadPoolTaskExecutor a good option?

Only four threads can run at a time

For this you can use a Fixed Thread Pool Executor

Application should not process any requests before 9 AM and after 7 PM.

for this you must use a Cron Trigger in Spring Task Executor. Follow this post

You should have totally 5 threads. One will be invoked by the Spring Task Executor when the Cron is Triggered and That thread should have a Fixed Thread Pool Executor which must spawn Child Threads. In this case maximum of 4.
