public class ConcurrentTaskExecutor extends Object implements org.springframework.core.task.AsyncListenableTaskExecutor, SchedulingTaskExecutor
java.util.concurrent.Executor and exposes
a Spring TaskExecutor for it.
Also detects an extended java.util.concurrent.ExecutorService, adapting
the AsyncTaskExecutor interface accordingly.
Autodetects a JSR-236 ManagedExecutorService
in order to expose ManagedTask adapters for it,
exposing a long-running hint based on SchedulingAwareRunnable and an identity
name based on the given Runnable/Callable's toString(). For JSR-236 style
lookup in a Java EE 7 environment, consider using DefaultManagedTaskExecutor.
Note that there is a pre-built ThreadPoolTaskExecutor that allows
for defining a ThreadPoolExecutor in bean style,
exposing it as a Spring TaskExecutor directly.
This is a convenient alternative to a raw ThreadPoolExecutor definition with
a separate definition of the present adapter class.
