Spring Batch is looking for source files during deployment

Question

I am developing Spring batch application on Spring Boot. Batch process is based on fire and forget, which means migration process is triggered by Http GET method and doesn't wait for result. There are 6 (six) csv files which containes migration data and these data must be processed and transferred to DB. Source files path is provided by application.yml file. Batch config (template) looks like as follows:

@Configuration
public class BeginCureBtachConfig {

@Value("$batch-files.begincure-source")
private String dataSourceFilePath;

@Autowired
IteamReader<BeginCure> itemReader;

@Autowired
ItemProcessor<BeginCure, BeginCure> itemProcessor;

@Bean Job beginCureJob(JobBuilderFactory jbFactory, StepBuilderDactory stp, ItemWriter<BeginCure> begnCure {
    //// code goes here
}

@Bean
public FlatFileItemReader<BeginCure> beginCureItemReader() {
   FlatFileItemReader<BeginCure> ffReader = new FlatFileItemReader<>();
   ffReader.setResource(new FileSystemResource(dataSourceFilePath));
   ffReader.setLineMapper(lineMapper());
   
   return ffReader;
}

@Bean
public LineMapper<BeginCure> lineMapper () {
  //..
 }
}

The problem is when project is deployed on openshift, batch looks for files even migratin is not triggered. In the code, I think this part of code giving some error ffReader.setResource(new FileSystemResource(dataSourceFilePath));

Is there any workaround or solution? Did anybody have this kind of problem?

Thank you in advance^^
