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

Deprecated.

as of 5.1, in favor of the EE 7/8 based DefaultManagedTaskExecutor

@Deprecated
public class WorkManagerTaskExecutor
extends JndiLocatorSupport
implements AsyncListenableTaskExecutor, SchedulingTaskExecutor, WorkManager, InitializingBean

TaskExecutor implementation that delegates to a CommonJ WorkManager, implementing the WorkManager 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.

Constructor Detail

WorkManagerTaskExecutor

public WorkManagerTaskExecutor()

Deprecated.

Method Detail

setWorkManager

public void setWorkManager(WorkManager workManager)

Deprecated.

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)

Deprecated.

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".

See Also:

setWorkManager(commonj.work.WorkManager), JndiLocatorSupport.setResourceRef(boolean)

setWorkListener

public void setWorkListener(WorkListener workListener)

Deprecated.

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)

Deprecated.

Specify a custom TaskDecorator to be applied to any Runnable 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 plain Runnable execution via execute calls. In case of #submit calls, the exposed Runnable will be a FutureTask which does not propagate any exceptions; you might have to cast it and call Future#get to evaluate exceptions.

afterPropertiesSet

public void afterPropertiesSet()
                        throws NamingException

Deprecated.

Description copied from interface: InitializingBean

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, 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 interface InitializingBean

Throws:

NamingException

execute

public void execute(Runnable task)

Deprecated.

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 Executor

Specified by:

execute in interface TaskExecutor

Parameters:

task - the Runnable to execute (never null)

execute

@Deprecated
public void execute(Runnable task,
                                long startTimeout)

Deprecated.

Description copied from interface: AsyncTaskExecutor

Execute the given task.

Specified by:

execute in interface AsyncTaskExecutor

Parameters:

task - the Runnable to execute (never null)

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 are AsyncTaskExecutor.TIMEOUT_IMMEDIATE or AsyncTaskExecutor.TIMEOUT_INDEFINITE (the default as used by TaskExecutor.execute(Runnable)).

See Also:

TaskExecutor.execute(Runnable)

submit

public Future<?> submit(Runnable task)

Deprecated.

Description copied from interface: AsyncTaskExecutor

Submit a Runnable task for execution, receiving a Future representing that task. The Future will return a null result upon completion.

Specified by:

Parameters:

task - the Runnable to execute (never null)

Returns:

a Future representing pending completion of the task

submit

public <T> Future<T> submit(Callable<T> task)

Deprecated.

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 interface AsyncTaskExecutor

Parameters:

task - the Callable to execute (never null)

Returns:

a Future representing pending completion of the task

submitListenable

public ListenableFuture<?> submitListenable(Runnable task)

Deprecated.

Description copied from interface: AsyncListenableTaskExecutor

Submit a Runnable task for execution, receiving a ListenableFuture representing that task. The Future will return a null result upon completion.

submitListenable

public <T> ListenableFuture<T> submitListenable(Callable<T> task)
