JOB REPOSITORY •It’s how Job, Step, JobParameters, JobExecution, and StepExecution
are persisted
• JobRepository • JobLauncher • JobRegistry • JobExplorer • PlatformTransactionManager
• JobBuilderFactory • StepBuilderFactory @EnableBatchProcessing
RUNNING JOBS • From the command Line (CommandLineJobRunner) • Within
a web container
