Use CustomizableThreadFactory as the default for ThreadPoolTaskExecutor [SPR-4564]

[spring-projects-issues]

Kenny MacLeod opened SPR-4564 and commented

The current default TheadFactory used by ThreadPoolTaskExecutor is Executors.defaultThreadFactory(). I suggest that a more useful default would be a CustomizableThreadFactory with the ThreadPoolTaskExecutor's bean name as the thread name prefix.

If not the default, then perhaps an easier way to specify it than manually injecting the thread factory?

Good point! I've even gone a step further now: ThreadPoolTaskExecutor extends CustomizableThreadFactory for common bean properties and uses itself as the default factory (initializing the thread name prefix with the bean name by default). This does not only give us the specific thread name prefix; it also gives consistent configurability directly at the executor level (analogous to SimpleAsyncTaskExecutor, and for both util.concurrent and backport-concurrent).
