This section answers questions that arise from using Spring Batch with Spring Boot.
83.1 Execute Spring Batch Jobs on Startup
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.
