public interface SchedulingTaskExecutor extends AsyncTaskExecutor
ATaskExecutorextension exposing scheduling characteristics that are relevant to potential task submitters.Scheduling clients are encouraged to submit
Runnablesthat match the exposed preferences of theTaskExecutorimplementation in use.Note:
SchedulingTaskExecutorimplementations are encouraged to also implement theAsyncListenableTaskExecutorinterface. This is not required due to the dependency on Spring 4.0's newListenableFutureinterface, which would make it impossible for third-party executor implementations to remain compatible with both Spring 4.0 and Spring 3.x.- 从以下版本开始:

Does thisTaskExecutorprefer short-lived tasks over long-lived tasks?A
SchedulingTaskExecutorimplementation can indicate whether it prefers submitted tasks to perform as little work as they can within a single task execution. For example, submitted tasks might break a repeated loop into individual subtasks which submit a follow-up task afterwards (if feasible).This should be considered a hint. Of course
TaskExecutorclients are free to ignore this flag and hence theSchedulingTaskExecutorinterface overall. However, thread pools will usually indicated a preference for short-lived tasks, to be able to perform more fine-grained scheduling.- 返回:
