org.springframework.batch.core.Step.execute()
Process the step and assign progress and status meta information to the {@link StepExecution} provided. The{@link Step} is responsible for setting the meta information and also saving it if required by theimplementation.
It is not safe to re-use an instance of {@link Step} to process multiple concurrent executions. @param stepExecution an entity representing the step to be executed @throws JobInterruptedException if the step is interrupted externally
