small_ticket :
I'm trying to use Async annotation in Spring but I'm getting
java.lang.IllegalStateException: ThreadPoolTaskScheduler not initialized
error, when I try to run the method marked as Async. The following is the configuration for Async:
@EnableScheduling
@EnableAsync
@Configuration
public class SchedulingConfiguration implements AsyncConfigurer{
@Override
public Executor getAsyncExecutor() {
ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
scheduler.setPoolSize(10);
return scheduler;
}
}
and the following is the declaration of async method.
@Async
@Transactional(value = "baseTransactionManager", isolation = Isolation.READ_COMMITTED)
public void foo(Bar bar) {// some code here}
What am I missing in here?
Thanks in advance.
Yaroslav Stavnichiy :
You have to explicitly call scheduler.initialize() after setting all properties but before returning the scheduler.
See full working test case here.
