runAsJob

public Job runAsJob(JobContextConsumer jobFunction)

runJobAsync

@Async
@Transactional
public void runJobAsync(Job job,
 JobContextConsumer jobFunction)

Runs a job asynchronously.

This method is annotated with @Transactional because outside of the Spring context, you cannot delete entities that are unmanaged by Hibernate. Adding @Transactional keeps the database session open and allows Hibernate to maintain it's knowledge of the object graph (i.e. the entities)

To learn more, read about Hibernate and the concept of a Spring Context.

Note that @Transactional means that if there is an unhandled exception, either every database transactions succeeds, or all of them are rolled back.

Parameters:

job -

jobFunction -

getJobLogs

public String getJobLogs(Long jobId)
