public class ConcurrentTaskExecutor extends Object implements 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.
