Using ThreadPoolTaskExecutor class in spring
Q. When to use Asynchronous execution?
Ans:-
When you want the seperate execution and you don’t want to wait for the executuin of the called method then in this senerio you can use the asynchronous execution.So Asynchromous excecution will be done by seperate thread.
Q. How to acheive Asynchronous execution?
Ans:-
Three Steps :-
1. using @EnableAsync annotation – this switches Spring’s ability to run @Async methods in a background thread pool.
2. using @Async annotation to the method -
Here 2 points to keep in mind :-
The method we are annotating with @Async needs to be public so that it can be proxied.
Self-invocation doesn’t work because it bypasses the proxy and calls the underlying method directly.
3. Creating Executor by using ThreadPoolTaskExecutor class
