  • You need to create manually instances of ItemProcessor with those names "headerProcessor", "detailProcessor", "trailerProcessor" – CaptainPyscho Jul 10 '22 at 01:43
  • @CaptainPyscho can you please explain little more in detail on how to do it ..Thank you – Onr Jul 10 '22 at 02:42

With a configuration class you could initialize your beans manually, specially if they need custom names.

@Configuration
public class MyCustomConfiguration {
   
   @Bean(name ="headerProcessor")
   public ItemProcessor<FileHeader, FileHeader> headerProcessorBean() {
      ItemProcessor<FileHeader, FileHeader> myBean = new HeaderProcessor<>();
      //Do whaterever you need to initilize your bean
      return myBean;
   }

   @Bean(name ="detailProcessor")
   public ItemProcessor<FileDetail, FileDetail> detailProcessorBean() {
      ItemProcessor<FileDetail, FileDetail> myBean = new ItemProcessor<>();
      //Do whaterever you need to initilize your bean
      return myBean;
   }
}

In this way these beans will be available for autowiring.
