Class WorkManagerTaskExecutor
- java.lang.Object
- org.springframework.jndi.JndiAccessor
- org.springframework.jndi.JndiLocatorSupport
- org.springframework.scheduling.commonj.WorkManagerTaskExecutor
- All Implemented Interfaces:
WorkManager,Executor,InitializingBean,AsyncListenableTaskExecutor,AsyncTaskExecutor,TaskExecutor,SchedulingTaskExecutor
public class WorkManagerTaskExecutor extends JndiLocatorSupport implements AsyncListenableTaskExecutor, SchedulingTaskExecutor, WorkManager, InitializingBean
TaskExecutor implementation that delegates to a CommonJ WorkManager, implementing theWorkManagerinterface, which either needs to be specified as reference or through the JNDI name.This is the central convenience class for setting up a CommonJ WorkManager in a Spring context.
Also implements the CommonJ WorkManager interface itself, delegating all calls to the target WorkManager. Hence, a caller can choose whether it wants to talk to this executor through the Spring TaskExecutor interface or the CommonJ WorkManager interface.
The CommonJ WorkManager will usually be retrieved from the application server's JNDI environment, as defined in the server's management console.
Note: On EE 7/8 compliant versions of WebLogic and WebSphere, a
DefaultManagedTaskExecutorshould be preferred, following JSR-236 support in Java EE 7/8.- Since:

WorkManagerTaskExecutor
public WorkManagerTaskExecutor()
Method Detail
setWorkManager
public void setWorkManager(WorkManager workManager)
Specify the CommonJ WorkManager to delegate to.Alternatively, you can also specify the JNDI name of the target WorkManager.
- See Also:
setWorkManagerName(java.lang.String)
setWorkManagerName
public void setWorkManagerName(String workManagerName)
Set the JNDI name of the CommonJ WorkManager.This can either be a fully qualified JNDI name, or the JNDI name relative to the current environment naming context if "resourceRef" is set to "true".
setWorkListener
public void setWorkListener(WorkListener workListener)
Specify a CommonJ WorkListener to apply, if any.This shared WorkListener instance will be passed on to the WorkManager by all
execute(java.lang.Runnable)calls on this TaskExecutor.
setTaskDecorator
public void setTaskDecorator(TaskDecorator taskDecorator)
Specify a customTaskDecoratorto be applied to anyRunnableabout to be executed.Note that such a decorator is not necessarily being applied to the user-supplied
Runnable/Callablebut rather to the actual execution callback (which may be a wrapper around the user-supplied task).The primary use case is to set some execution context around the task's invocation, or to provide some monitoring/statistics for task execution.
NOTE: Exception handling in
TaskDecoratorimplementations is limited to plainRunnableexecution viaexecutecalls. In case of#submitcalls, the exposedRunnablewill be aFutureTaskwhich does not propagate any exceptions; you might have to cast it and callFuture#getto evaluate exceptions.- Since:

afterPropertiesSet
public void afterPropertiesSet() throws NamingException
Description copied from interface:InitializingBeanInvoked by the containingBeanFactoryafter it has set all bean properties and satisfiedBeanFactoryAware,ApplicationContextAwareetc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
- Specified by:
afterPropertiesSetin interfaceInitializingBean- Throws:
NamingException
execute
public void execute(Runnable task)
Description copied from interface:TaskExecutorExecute the giventask.The call might return immediately if the implementation uses an asynchronous execution strategy, or might block in the case of synchronous execution.
- Specified by:
executein interfaceExecutor- Specified by:
executein interfaceTaskExecutor- Parameters:
task- theRunnableto execute (nevernull)
execute
public void execute(Runnable task, long startTimeout)
Description copied from interface:AsyncTaskExecutorExecute the giventask.- Specified by:
executein interfaceAsyncTaskExecutor- Parameters:
task- theRunnableto execute (nevernull)startTimeout- the time duration (milliseconds) within which the task is supposed to start. This is intended as a hint to the executor, allowing for preferred handling of immediate tasks. Typical values areAsyncTaskExecutor.TIMEOUT_IMMEDIATEorAsyncTaskExecutor.TIMEOUT_INDEFINITE(the default as used byTaskExecutor.execute(Runnable)).
submit
public Future<?> submit(Runnable task)
Description copied from interface:AsyncTaskExecutorSubmit a Runnable task for execution, receiving a Future representing that task. The Future will return anullresult upon completion.- Specified by:
submitin interfaceAsyncTaskExecutor- Parameters:
task- theRunnableto execute (nevernull)- Returns:
- a Future representing pending completion of the task
submit
public <T> Future<T> submit(Callable<T> task)
Description copied from interface:AsyncTaskExecutorSubmit a Callable task for execution, receiving a Future representing that task. The Future will return the Callable's result upon completion.- Specified by:
submitin interfaceAsyncTaskExecutor- Parameters:
task- theCallableto execute (nevernull)- Returns:
- a Future representing pending completion of the task
submitListenable
public ListenableFuture<?> submitListenable(Runnable task)
Description copied from interface:AsyncListenableTaskExecutorSubmit aRunnabletask for execution, receiving aListenableFuturerepresenting that task. The Future will return anullresult upon completion.- Specified by:
submitListenablein interfaceAsyncListenableTaskExecutor- Parameters:
task- theRunnableto execute (nevernull)- Returns:
- a
ListenableFuturerepresenting pending completion of the task
submitListenable
public <T> ListenableFuture<T> submitListenable(Callable<T> task)
Description copied from interface:AsyncListenableTaskExecutorSubmit aCallabletask for execution, receiving aListenableFuturerepresenting that task. The Future will return the Callable's result upon completion.- Specified by:

task- theCallableto execute (nevernull)- Returns:
- a
ListenableFuturerepresenting pending completion of the task
prefersShortLivedTasks
