                         JobExecutionNotRunningException

Description copied from interface: JobService

Send a signal to a job execution to stop processing. This method does not guarantee that the processing will stop, only that the signal will be delivered. It is up to the individual Job and Step implementations to ensure that the signal is obeyed. In particular, if users provide a custom Tasklet to a Step it must check the signal in the JobExecution itself.

Specified by:

stop in interface JobService

Parameters:

jobExecutionId - the job execution id to stop

Returns:

the JobExecution that was stopped

Throws:

NoSuchJobExecutionException

JobExecutionNotRunningException

Description copied from interface: JobService

Mark the JobExecution as ABANDONED. If a stop signal is ignored because the process died this is the best way to mark a job as finished with (as opposed to STOPPED). An abandoned job execution can be restarted, but a stopping one cannot.

Specified by:

abandon in interface JobService

Parameters:

jobExecutionId - the job execution id to abort

Returns:

the JobExecution that was aborted

Throws:

NoSuchJobExecutionException

JobExecutionAlreadyRunningException - if the job is running (it should be stopped first)
