schedule

public java.util.concurrent.ScheduledFuture<?> schedule(java.lang.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, e.g. a CronTrigger object wrapping a cron expression

Returns:

a ScheduledFuture representing pending completion of the task, or null if the given Trigger object never fires (i.e. returns null from Trigger.nextExecutionTime(org.springframework.scheduling.TriggerContext))

schedule

public java.util.concurrent.ScheduledFuture<?> schedule(java.lang.Runnable task,
                                                        java.util.Date 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 completion of the task

scheduleAtFixedRate

public java.util.concurrent.ScheduledFuture<?> scheduleAtFixedRate(java.lang.Runnable task,
                                                                   java.util.Date startTime,
                                                                   long 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 (in milliseconds)

Returns:

a ScheduledFuture representing pending completion of the task

scheduleAtFixedRate

public java.util.concurrent.ScheduledFuture<?> scheduleAtFixedRate(java.lang.Runnable task,
                                                                   long 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 (in milliseconds)

Returns:

a ScheduledFuture representing pending completion of the task

scheduleWithFixedDelay

public java.util.concurrent.ScheduledFuture<?> scheduleWithFixedDelay(java.lang.Runnable task,
                                                                      java.util.Date startTime,
