I have a single step springbatch application. The job is as follows:
@Bean
public Job databaseCursorJob(@Qualifier("databaseCursorStep") Step exampleJobStep,
JobBuilderFactory jobBuilderFactory) {
return jobBuilderFactory.get("databaseCursorJob")
.incrementer(new RunIdIncrementer())
.flow(exampleJobStep)
.end()
.build();
}
I start the job from a springboot application. This afternoon, I attempted to add a second step to the job. Essentially as follows:
@Bean
public Job databaseCursorJob(@Qualifier("databaseCursorStep") Step exampleJobStep,
JobBuilderFactory jobBuilderFactory) {
return jobBuilderFactory.get("databaseCursorJob")
.incrementer(new RunIdIncrementer())
.flow(exampleJobStep).next(partitionStep())
.end()
.build();
}
In other words, just adding the "next(partitionStep()). However, ever since I did this, the job finishes without executing any step (see shell output below). In fact, even after removing the second step and going back to the original job, it refuses to execute the step. Before attempting to add the second step, I never once encountered this problem. I have gone so far as restarting my VM and it still skips the step. I am rather dead in the water until I resolved this. Grateful for any insights. thanks.

on the step. Both of them should fix your issue. – Hsining
