Spring Batch auto-configuration is enabled by adding @EnableBatchProcessing
(from Spring Batch) somewhere in your context.
By default, it executes all Jobs in the application context on startup (see
JobLauncherCommandLineRunner
for details). You can narrow down to a specific job or jobs by specifying
spring.batch.job.names (which takes a comma-separated list of job name patterns).
If the application context includes a JobRegistry, the jobs in
spring.batch.job.names are looked up in the registry instead of being autowired from the
context. This is a common pattern with more complex systems, where multiple jobs are
defined in child contexts and registered centrally.
See BatchAutoConfiguration and @EnableBatchProcessing for more details.
