直接已知子类:
DefaultManagedTaskScheduler
```
public class ConcurrentTaskScheduler
extends ConcurrentTaskExecutor
implements TaskScheduler
```
Adapter that takes a java.util.concurrent.ScheduledExecutorService and exposes a Spring TaskScheduler for it. Extends ConcurrentTaskExecutor in order to implement the SchedulingTaskExecutor interface as well.
Autodetects a JSR-236 ManagedScheduledExecutorService in order to use it for trigger-based scheduling if possible, instead of Spring's local trigger management which ends up delegating to regular delay-based scheduling against the java.util.concurrent.ScheduledExecutorService API. For JSR-236 style lookup in a Java EE 7 environment, consider using DefaultManagedTaskScheduler.
Note that there is a pre-built ThreadPoolTaskScheduler that allows for defining a ScheduledThreadPoolExecutor in bean style, exposing it as a Spring TaskScheduler directly. This is a convenient alternative to a raw ScheduledThreadPoolExecutor definition with a separate definition of the present adapter class.

  - ConcurrentTaskScheduler
```
public ConcurrentTaskScheduler()
```
    Create a new ConcurrentTaskScheduler, using a single thread executor as default.

    Executors.newSingleThreadScheduledExecutor()
  - ConcurrentTaskScheduler
```
public ConcurrentTaskScheduler(ScheduledExecutorService scheduledExecutor)
```
    Create a new ConcurrentTaskScheduler, using the given ScheduledExecutorService as shared delegate.
    Autodetects a JSR-236 ManagedScheduledExecutorService in order to use it for trigger-based scheduling if possible, instead of Spring's local trigger management.
    参数:
    scheduledExecutor - the ScheduledExecutorService to delegate to for SchedulingTaskExecutor as well as TaskScheduler invocations
  - ConcurrentTaskScheduler
```
public ConcurrentTaskScheduler(Executor concurrentExecutor,
                               ScheduledExecutorService scheduledExecutor)
```
    Create a new ConcurrentTaskScheduler, using the given Executor and ScheduledExecutorService as delegates.
    Autodetects a JSR-236 ManagedScheduledExecutorService in order to use it for trigger-based scheduling if possible, instead of Spring's local trigger management.
    参数:
    concurrentExecutor - the Executor to delegate to for SchedulingTaskExecutor invocations
    scheduledExecutor - the ScheduledExecutorService to delegate to for TaskScheduler invocations

  - setScheduledExecutor
```
public final void setScheduledExecutor(ScheduledExecutorService scheduledExecutor)
```
    Specify the ScheduledExecutorService to delegate to.
    Autodetects a JSR-236 ManagedScheduledExecutorService in order to use it for trigger-based scheduling if possible, instead of Spring's local trigger management.
    Note: This will only apply to TaskScheduler invocations. If you want the given executor to apply to SchedulingTaskExecutor invocations as well, pass the same executor reference to ConcurrentTaskExecutor.setConcurrentExecutor(java.util.concurrent.Executor).
