Use '@EnableBatchProcessing' carefully on Spring Boot3.

When using '@EnableBatchProcessing' in Spring Boot3, default settings are initialized. Therefore, batch operation may not work.

With Spring Boot 3, it is no longer required to use @EnableBatchProcessing to enable Spring Boot’s auto-configuration of Spring Batch. If you use that annotation, the auto-configuration of batch (including the automatic job execution at startup) will back-off.

There is a section about this change in the migration guide of Spring Boot 3: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#spring-batch-changes . There is also a note as well in the getting started guide of Spring Batch: https://spring.io/guides/gs/batch-processing (See Note how the application does not use the @EnableBatchProcessing annotation..). Is this what you are looking for?

That's right. I was able to remove @EnableBatchProcessing by looking at "https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#spring-batch-changes". However, there is no warning about back-off in "https://docs.spring.io/spring-batch/reference/job/java-config.html". Therefore, I added a cautionary note to “https://github.com/spring-projects/spring-batch/pull/4606”!
