I am using Spring Batch to read some data from CSV files and put it in a database.
My Batch job must be compound of 2 steps :

1. Check files (names, extension, content ..)
2. Read lines from CSV and save them in DB (ItemReader, ItemProcessor,
ItemWriter..)

`Step 2` must not be executed if `Step 1` generated an error (files are not conform, files doesn't exist ...)

FYI, I am using Spring Batch without XML configuration ! Only annotations :
Here's what my job config class looks like :

```
@Configuration
@EnableBatchProcessing
public class ProductionOutConfig {

    @Autowired
    private StepBuilderFactory steps;

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private ProductionOutTasklet productionOutTasklet;

    @Autowired
    private CheckFilesForProdTasklet checkFilesForProdTasklet;

    @Bean
    public Job productionOutJob(@Qualifier("productionOut")Step productionOutStep,
                                @Qualifier("checkFilesForProd") Step checkFilesForProd){
        return jobBuilderFactory.get("productionOutJob").start(checkFilesForProd).next(productionOutStep).build();
    }

    @Bean(name="productionOut")
    public Step productionOutStep(){
        return steps.get("productionOut").
                tasklet(productionOutTasklet)
                .build();}

    @Bean(name = "checkFilesForProd")
    public Step checkFilesForProd(){
        return steps.get("checkFilesForProd")
                .tasklet(checkFilesForProdTasklet)
                .build();
    }
}

```
