Spring batch stop the ItemReader running when app starts - spring

Question

I'm using Spring Batch to run jobs which are triggered from a controller method. Everything works fine except when the application first boots the ItemReader runs and reads through everything.
Is this expected behaviour? It's not really a big deal it just slows down the boot time by a good 500 seconds.
Note: The job itself isn't running as I've disabled that via
batch:
job:
enabled: false
Edit:
Configuration
#Slf4j
#Configuration
#EnableBatchProcessing
public class JobConfiguration {
#Value("${app.directoryPath}")
public String directoryPath;
private final JobBuilderFactory jobBuilderFactory;
private final StepBuilderFactory stepBuilderFactory;
private final LocationRepository locationRepository;
private final VideoRepository videoRepository;
public JobConfiguration(JobBuilderFactory jobBuilderFactory, StepBuilderFactory stepBuilderFactory, LocationRepository locationRepository, VideoRepository videoRepository) {
this.jobBuilderFactory = jobBuilderFactory;
this.stepBuilderFactory = stepBuilderFactory;
this.locationRepository = locationRepository;
this.videoRepository = videoRepository;
}
#Bean(name = "importVideo")
public Job importVideo(Step processVideos) {
return jobBuilderFactory
.get("importVideo")
.start(processVideos)
.build();
}
#Bean(name = "processVideos")
public Step processVideos(VideoItemReader videoItemReader, VideoProcessor videoProcessor, VideoWriter videoWriter) {
return stepBuilderFactory.get("processVideos").<File, Video>chunk(25)
.reader(videoItemReader)
.processor(videoProcessor)
.writer(videoWriter)
.build();
}
#Bean
public VideoWriter videoWriter() {
return new VideoWriter(videoRepository);
}
#Bean
public VideoProcessor videoProcessor() {
return new VideoProcessor(locationRepository);
}
#Bean
public VideoItemReader videoItemReader() {
return new VideoItemReader("file:" + directoryPath, locationRepository);
}
}
And I'm calling the job with a GET request via
#GetMapping("/jobs/{job}")
public ResponseEntity<String> importVideos(#PathVariable String job) {
if (job.equalsIgnoreCase("createThumbnails")) {
executeJob(createThumbnails);
} else if (job.equalsIgnoreCase("importVideo")) {
executeJob(importVideo);
}
return new ResponseEntity<>("running", HttpStatus.OK);
}
private void executeJob(Job job) {
Set<JobExecution> runningJobExecutions = jobExplorer.findRunningJobExecutions(job.getName());
if (runningJobExecutions.isEmpty()) {
try {
jobLauncher.run(job, new JobParameters());
} catch (Exception ex) {
log.error(ex.getMessage());
}
} else {
log.info("executeJob already running, so... NOPE!");
}
}
But how I'm calling it has nothing to do with it, if I delete that code the same behaviour still exists...

Answer 1

This would be mostly due to spring not recognising spring.batch.job.enabled property, please try adding this in your
Load your property explicitly in your Application class, hopefully this will solve the issue.
#PropertySource("classpath:batch.properties")

Answer 2

Figured out my issue, the problem was my custom reader implementation was also implementing InitializingBean where it was calling what was effectively 'getVideos()'.
Removing the InitializingBean interface stopped the reader running on each boot.
