Class TaskSchedulerRouter

java.lang.Object
org.springframework.scheduling.config.TaskSchedulerRouter
All Implemented Interfaces:
Aware, BeanFactoryAware, BeanNameAware, DisposableBean, TaskScheduler
public class TaskSchedulerRouter extends Object implements TaskScheduler, BeanNameAware, BeanFactoryAware, DisposableBean
A routing implementation of the TaskScheduler interface, delegating to a target scheduler based on an identified qualifier or using a default scheduler otherwise.
Since:
6.1

    • DEFAULT_TASK_SCHEDULER_BEAN_NAME

      public static final String DEFAULT_TASK_SCHEDULER_BEAN_NAME
      The default name of the TaskScheduler bean to pick up: "taskScheduler".

      Note that the initial lookup happens by type; this is just the fallback in case of multiple scheduler beans found in the context.

    • setBeanName

      public void setBeanName(@Nullable String name)
      The bean name for this router, or the bean name of the containing bean if the router instance is internally held.
      Specified by:
      setBeanName in interface BeanNameAware
      Parameters:
      name - the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use the BeanFactoryUtils.originalBeanName(String) method to extract the original bean name (without suffix), if desired.

    • setBeanFactory

      public void setBeanFactory(@Nullable BeanFactory beanFactory)
      The bean factory for scheduler lookups.
      Specified by:
      setBeanFactory in interface BeanFactoryAware
      Parameters:
      beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

    • schedule

      @Nullable public ScheduledFuture<?> schedule(Runnable task, Trigger trigger)
      Description copied from interface: TaskScheduler
      Schedule the given Runnable, invoking it whenever the trigger indicates a next execution time.

      Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.

      Specified by:
      schedule in interface TaskScheduler
      Parameters:
      task - the Runnable to execute whenever the trigger fires
      trigger - an implementation of the Trigger interface, for example, a CronTrigger object wrapping a cron expression
      Returns:
      a ScheduledFuture representing pending execution of the task, or null if the given Trigger object never fires (i.e. returns null from Trigger.nextExecution(org.springframework.scheduling.TriggerContext))

    • schedule

      public ScheduledFuture<?> schedule(Runnable task, Instant startTime)
      Description copied from interface: TaskScheduler
      Schedule the given Runnable, invoking it at the specified execution time.

      Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.

      Specified by:
      schedule in interface TaskScheduler
      Parameters:
      task - the Runnable to execute whenever the trigger fires
      startTime - the desired execution time for the task (if this is in the past, the task will be executed immediately, i.e. as soon as possible)
      Returns:
      a ScheduledFuture representing pending execution of the task

    • scheduleAtFixedRate

      public ScheduledFuture<?> scheduleAtFixedRate(Runnable task, Instant startTime, Duration period)
      Description copied from interface: TaskScheduler
      Schedule the given Runnable, invoking it at the specified execution time and subsequently with the given period.

      Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.

      Specified by:
      scheduleAtFixedRate in interface TaskScheduler
      Parameters:
      task - the Runnable to execute whenever the trigger fires
      startTime - the desired first execution time for the task (if this is in the past, the task will be executed immediately, i.e. as soon as possible)
      period - the interval between successive executions of the task
      Returns:
      a ScheduledFuture representing pending execution of the task

    • scheduleAtFixedRate

      public ScheduledFuture<?> scheduleAtFixedRate(Runnable task, Duration period)
      Description copied from interface: TaskScheduler
      Schedule the given Runnable, starting as soon as possible and invoking it with the given period.

      Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.

      Specified by:
      scheduleAtFixedRate in interface TaskScheduler
      Parameters:
      task - the Runnable to execute whenever the trigger fires
      period - the interval between successive executions of the task
      Returns:
      a ScheduledFuture representing pending execution of the task

    • scheduleWithFixedDelay

      public ScheduledFuture<?> scheduleWithFixedDelay(Runnable task, Instant startTime, Duration delay)
      Description copied from interface: TaskScheduler
      Schedule the given Runnable, invoking it at the specified execution time and subsequently with the given delay between the completion of one execution and the start of the next.

      Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.

      Specified by:
      scheduleWithFixedDelay in interface TaskScheduler
      Parameters:
      task - the Runnable to execute whenever the trigger fires
      startTime - the desired first execution time for the task (if this is in the past, the task will be executed immediately, i.e. as soon as possible)
      delay - the delay between the completion of one execution and the start of the next
      Returns:
      a ScheduledFuture representing pending execution of the task

    • scheduleWithFixedDelay

      public ScheduledFuture<?> scheduleWithFixedDelay(Runnable task, Duration delay)
      Description copied from interface: TaskScheduler
      Schedule the given Runnable, starting as soon as possible and invoking it with the given delay between the completion of one execution and the start of the next.

      Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.

      Specified by:
      scheduleWithFixedDelay in interface TaskScheduler
      Parameters:
      task - the Runnable to execute whenever the trigger fires
      delay - the delay between the completion of one execution and the start of the next
