public class SimpleTaskWorkManager extends Object implements WorkManager
WorkManager
implementation that
delegates to a Spring TaskExecutor
.
Provides simple task execution including start timeouts, but without support
for a JCA ExecutionContext (i.e. without support for imported transactions).
Uses a SyncTaskExecutor
for doWork(javax.resource.spi.work.Work)
calls and a SimpleAsyncTaskExecutor
for startWork(javax.resource.spi.work.Work)
and scheduleWork(javax.resource.spi.work.Work)
calls, by default.
These default task executors can be overridden through configuration.
NOTE: This WorkManager does not provide thread pooling by default!
Specify a ThreadPoolTaskExecutor
(or any other thread-pooling TaskExecutor) as "asyncTaskExecutor" in order to
achieve actual thread pooling.
This WorkManager automatically detects a specified
AsyncTaskExecutor
implementation
and uses its extended timeout functionality where appropriate.
JCA WorkListeners are fully supported in any case.

public void setSyncTaskExecutor(TaskExecutor syncTaskExecutor)
doWork(javax.resource.spi.work.Work)
calls).
Default is a SyncTaskExecutor
.
public void setAsyncTaskExecutor(AsyncTaskExecutor asyncTaskExecutor)
startWork(javax.resource.spi.work.Work)
and scheduleWork(javax.resource.spi.work.Work)
calls).
This will typically (but not necessarily) be an
AsyncTaskExecutor
implementation.
Default is a SimpleAsyncTaskExecutor
.

taskExecutor
- the TaskExecutor to usework
- the Work to executestartTimeout
- the time duration within which the Work is supposed to startblockUntilStarted
- whether to block until the Work has startedexecutionContext
- the JCA ExecutionContext for the given WorkworkListener
- the WorkListener to clal for the given WorkWorkException
- if the TaskExecutor did not accept the Work
