AbortableTaskDecorator

public AbortableTaskDecorator(org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor taskExecutor,
 ScheduledThreadPoolExecutor timeoutExecutor)

Construct an instance.

Parameters:

taskExecutor - The executor that will execute the runnable we're decorating.

Method Details

decorate

public Runnable decorate(Runnable runnable)

We create a new AbortableTaskRunnable that holds the current thread's MDC. This is for logging purposes, so that logging within the runnable is done with the correct logging context. For instance, the transaction id is logged and the current user etc.

Next to this, we create an schedule a TimeoutGuardTask. This task will stop the runnable we're decorating if the configured timeout has lapsed.

The AbortableTaskRunnable will stop the execution of the TimeoutGuardTask after it completes.

Specified by:

decorate in interface org.springframework.core.task.TaskDecorator

Parameters:

runnable - The runnable to decorate.

Returns:

a decorated runnable.
