JobExecutionListener (Spring Batch 4.1.4.RELEASE API)

All Known Implementing Classes:
CompositeJobExecutionListener, JobExecutionListenerSupport, JobListenerAdapter
```
public interface JobExecutionListener
```
Provide callbacks at specific points in the lifecycle of a Job. Implementations can be stateful if they are careful to either ensure thread safety, or to use one instance of a listener per job, assuming that job instances themselves are not used by more than one thread.
