Description

« Hide

Developers find StepContext easy to locate and use, and mistakenly assume that its attributes ight be persisted (like the ExecutionContext). It's an easy mistake to make, so maybe user defined attributes in StepContext should use an ExecutionContext, or maybe a separate API in StepContext could provide the same feature.

We decided not to merge them, but StepContext is dying anyway (still TODO).

Added an accessor for job parameters in StepExecution - make StepListener the best place to get hold of JobParameters.

Refactored existing StepContextAware to StepListener implementations. The BatchResourceFactoryBean is now a ProxyResource with a hint in docos and exception messages about registering with a step.

StepScope is dead in favour of explicit listener registration. TODO: remove unnecessary delegate calls in ItemStreams.
