I upgraded to Spring Boot 3 and all of a sudden my batch application doesn't start any jobs when I specify them via --spring.batch.job.names.
This is my main class:
@SpringBootApplication
@EnableJpaRepositories("path.to.my.repositories")
@EntityScan("path.to.my.entities")
public class MyBatchApplication{
public static void main(String[] args) {
System.exit(SpringApplication.exit(SpringApplication.run(MyBatchApplication.class, args)));
}
}
This is my config
@Configuration
@EnableBatchProcessing(modular = true)
public class MyModularBatchJobContextConfiguration {
@Bean
ApplicationContextFactory getJobAContext() {
return new GenericApplicationContextFactory(JobAConfig.class);
}
@Bean
ApplicationContextFactory getJobBContext() {
return new GenericApplicationContextFactory(JobBConfig.class);
}
}
and JobA.class and JobB.class basically the same like:
public class JobAConfig {
private static final String MY_JOB_NAME = "jobA"
@Autowired
private EntityManagerFactory emf;
@Bean
public Job jobA(JobRepository jobRepository, Step myStep) {
return new JobBuilder(MY_JOB_NAME, jobRepository)
.flow(myStep)
.end()
.build();
}
@Bean
public Step myStep(JpaTransactionManager transactionManager,
JobRepository jobRepository,
FlatFileItemReader<MyEntity> reader,
ItemProcessor<MyEntity, MyEntity> processor,
JpaItemWriter<MyEntity> entityWriter) {
return new StepBuilder(MY_STEP_NAME, jobRepository)
.<MyEntity, MyEntity>chunk(10, transactionManager)
.reader(reader)
.processor(processor)
.writer(plzOrtEntityWriter)
.transactionManager(transactionManager)
.build();
}
// Reader, Writer, Processor...
when i run the jar with java -jar mybatchapplication.jar --spring.batch.job.names=jobA nothing happens, the job is not started.

Does anybody know whats wrong here?
I also tried with --spring.batch.job.name=, no success.
With Spring Boot 3, there is no need for @EnableBatchProcessing. If you add it, the auto-configuration of Spring Batch (meta-data tables creation, launching of jobs at startup, etc) will back off. This is mentioned in the migration guide of Spring Boot 3.
So in your case, if you want to modularize your context, you have two options:
@EnableBatchProcessing to benefit from modular = true, but in that case you have to manually do what Spring Boot used to previously do (ie initialize the database, run the job at startup, etc).@EnableBatchProcessing (to benefit from Boot 3 features as before), but in that case you need to modularize your context manually
