如何将数据传入spring batch ItemProcessor？

public class MyItemProcessor implements ItemProcessor<InputData, OutputData> {

    @Override
    public OutputData process(InputData inputData) throws Exception {
        // 对输入数据进行处理
        // ...

        // 返回处理后的数据
        return outputData;
    }
}

@Configuration
@EnableBatchProcessing
public class BatchConfiguration {

    @Autowired
    private JobBuilderFactory jobBuilderFactory;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;

    @Autowired
    private ItemReader<InputData> itemReader;

    @Autowired
    private ItemWriter<OutputData> itemWriter;

    @Autowired
    private ItemProcessor<InputData, OutputData> itemProcessor;

    @Bean
    public Step myStep() {
        return stepBuilderFactory.get("myStep")
                .<InputData, OutputData>chunk(10)
                .reader(itemReader)
                .processor(itemProcessor)
                .writer(itemWriter)
                .build();
    }

    @Bean
    public Job myJob() {
        return jobBuilderFactory.get("myJob")
                .start(myStep())
                .build();
    }
}
