Class SimpleThreadPoolTaskExecutor

  extended by org.quartz.simpl.SimpleThreadPool
      extended by org.springframework.scheduling.quartz.SimpleThreadPoolTaskExecutor
All Implemented Interfaces:
ThreadPool, DisposableBean, InitializingBean, TaskExecutor, SchedulingTaskExecutor

public class SimpleThreadPoolTaskExecutor
extends SimpleThreadPool
implements SchedulingTaskExecutor, InitializingBean, DisposableBean

Subclass of Quartz's SimpleThreadPool that implements Spring's TaskExecutor interface and listens to Spring lifecycle callbacks.

Can be used as a thread-pooling TaskExecutor backend, in particular on JDK <= 1.5 (where the JDK ThreadPoolExecutor isn't available yet). Can be shared between a Quartz Scheduler (specified as "taskExecutor") and other TaskExecutor users, or even used completely independent of a Quartz Scheduler (as plain TaskExecutor backend).

Set whether to wait for running jobs to complete on shutdown. Default is "false".

public void afterPropertiesSet()
                        throws SchedulerConfigException
Description copied from interface: InitializingBean
Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:
afterPropertiesSet in interface InitializingBean


public void execute(Runnable task)
Description copied from interface: TaskExecutor
Execute the given task.

The call might return immediately if the implementation uses an asynchronous execution strategy, or might block in the case of synchronous execution.

Specified by:
execute in interface TaskExecutor
task - the Runnable to execute (never null)


public boolean prefersShortLivedTasks()
This task executor prefers short-lived work units.

Specified by:
prefersShortLivedTasks in interface SchedulingTaskExecutor
true if this TaskExecutor prefers short-lived tasks


public void destroy()
Description copied from interface: DisposableBean
Invoked by a BeanFactory on destruction of a singleton.

Specified by:
destroy in interface DisposableBean
