I am trying to migrate data between different MongoDB databases and for this purpose create a simple demo. After fixing deprecated dependency errors (I use 'spring-batch-core', version: '5.1.2') related to Spring Batch, now I am getting “Parameter 1 of constructor in BatchConfig required a bean of type ‘org.springframework.batch.core.repository.JobRepository’ that could not be found.” error in the BatchConfig class shown below.

@Configuration
@RequiredArgsConstructor
// @EnableBatchProcessing
public class BatchConfig {
// public class BatchConfig extends DefaultBatchConfiguration {

    private final StudentReactiveRepository studentReactiveRepository;
    private final JobRepository jobRepository;
    private final PlatformTransactionManager transactionManager;

    @Bean
    public ItemReader<Student> studentItemReader() {
        Flux<Student> students = studentReactiveRepository.findAll();
        return new IteratorItemReader<>(students.toIterable());
    }

    @Bean
    public ItemWriter<Student> studentItemWriter() {
        return students -> {
            for (Student student : students) {
                studentReactiveRepository.save(student).block();
            }
        };
    }

    @Bean
    public Step processStudentStep() {
        return new StepBuilder("processStudentStep", jobRepository)
                .<Student, Student>chunk(10, transactionManager)
                .reader(studentItemReader())
                // .processor(processor())
                .writer(studentItemWriter())
                // .taskExecutor(taskExecutor())
                .build();
    }

    @Bean
    public Job studentProcessingJob() {
        return new JobBuilder("studentProcessingJob", jobRepository)
                .start(processStudentStep())
                .build();
    }
}

I have tried several workarounds as commented out in the config and some others, but still not fixed. Is there any workaround to fix the problem? I would also be appreciated if there is any suggestion for some implementation examples of migrating data between MongoD databases using Spring Batch?
