org.springframework.batch.core.job.SimpleJob
Simple implementation of {@link Job} interface providing the ability to run a{@link JobExecution}. Sequentially executes a job by iterating through its list of steps. Any {@link Step} that fails will fail the job. The job isconsidered complete when all steps have been executed. @author Lucas Ward @author Dave Syer @author Michael Minella
