/**
* {@link EnableAutoConfiguration Auto-configuration} for Spring Batch. By default a
* Runner will be created and all jobs in the context will be executed on startup.
*
* Disable this behavior with {@literal spring.batch.job.enabled=false}).
*
* Alternatively, discrete Job names to execute on startup can be supplied by the User
* with a comma-delimited list: {@literal spring.batch.job.names=job1,job2}. In this case
* the Runner will first find jobs registered as Beans, then those in the existing
* JobRegistry.
