I am using Spring Batch in project and using ClassifierCompositeItemWriter to classify records and then using MultiResourceItemWriterBuilder to create multiple files. In my case more than 1 files is getting created, but I’d want to understand is there any way to count no. of files created by each Writer within CompositeItemWriter. How can we do that?

@Bean
public ItemWriter<Employee> javaDeveloperItemWriter() {
       FlatFileItemWriter<Employee> itemWriter = new FlatFileItemWriterBuilder<Employee>()
                .lineAggregator(new PassThroughLineAggregator<>())
                .name("itemsWriter")
                .build();

        return new MultiResourceItemWriterBuilder<Employee>()
                .name("javaDeveloperItemWriter")
                .delegate(itemWriter)
                .resource(new FileSystemResource("AAA01.CPP.CA."+ LocalDate.now()))
                .itemCountLimitPerResource(2)
                .resourceSuffixCreator(index -> "-S1.V" + index+".K1.P1.data.csv")
                .build();
    }
