WorkManager

,InitializingBean
,AsyncListenableTaskExecutor
,AsyncTaskExecutor
,TaskExecutor
,SchedulingTaskExecutor
public class WorkManagerTaskExecutor extends JndiLocatorSupport implements AsyncListenableTaskExecutor, SchedulingTaskExecutor, WorkManager, InitializingBean
TaskExecutor implementation that delegates to a CommonJ WorkManager, implementing theWorkManager
interface, 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
DefaultManagedTaskExecutor
should 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 customTaskDecorator
to be applied to anyRunnable
about to be executed.Note that such a decorator is not necessarily being applied to the user-supplied
Runnable
/Callable
but 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
TaskDecorator
implementations is limited to plainRunnable
execution viaexecute
calls. In case of#submit
calls, the exposedRunnable
will be aFutureTask
which does not propagate any exceptions; you might have to cast it and callFuture#get
to evaluate exceptions.- Since:
- 4.3
afterPropertiesSet
public void afterPropertiesSet() throws NamingException
Description copied from interface:InitializingBean
Invoked by the containingBeanFactory
after it has set all bean properties and satisfiedBeanFactoryAware
,ApplicationContextAware
etc.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:
afterPropertiesSet
in interfaceInitializingBean
- Throws:
NamingException
execute
public void execute(Runnable task)
Description copied from interface:TaskExecutor
Execute 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:
execute
in interfaceExecutor
- Specified by:
execute
in interfaceTaskExecutor
- Parameters:
task
- theRunnable
to execute (nevernull
)
execute
public void execute(Runnable task, long startTimeout)
Description copied from interface:AsyncTaskExecutor
Execute the giventask
.- Specified by:
execute
in interfaceAsyncTaskExecutor
- Parameters:
task
- theRunnable
to 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_IMMEDIATE
orAsyncTaskExecutor.TIMEOUT_INDEFINITE
(the default as used byTaskExecutor.execute(Runnable)
).
submit
public Future<?> submit(Runnable task)
Description copied from interface:AsyncTaskExecutor
Submit a Runnable task for execution, receiving a Future representing that task. The Future will return anull
result upon completion.- Specified by:
submit
in interfaceAsyncTaskExecutor
- Parameters:
task
- theRunnable
to execute (nevernull
)- Returns:
- a Future representing pending completion of the task
submit
public <T> Future<T> submit(Callable<T> task)
Description copied from interface:AsyncTaskExecutor
Submit a Callable task for execution, receiving a Future representing that task. The Future will return the Callable's result upon completion.- Specified by:
submit
in interfaceAsyncTaskExecutor
- Parameters:
task
- theCallable
to execute (nevernull
)- Returns:
- a Future representing pending completion of the task
submitListenable
public ListenableFuture<?> submitListenable(Runnable task)
Description copied from interface:AsyncListenableTaskExecutor
Submit aRunnable
task for execution, receiving aListenableFuture

submitListenable
in interfaceAsyncListenableTaskExecutor
- Parameters:
