所有已实现的接口:

SpringExecutor, ExecutorAdapter<ThreadPoolExecutor>, Executor, ExecutorService, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.core.task.AsyncTaskExecutor, org.springframework.core.task.TaskExecutor

public class OrderedDtpExecutor
extends DtpExecutor

OrderedDtpExecutor can ensure that the delivered tasks are executed according to the key and task submission order. It is applicable to scenarios where the throughput is improved through parallel processing and the tasks are run in a certain order.
