Spring Batch ResourceAware - 在 ClassifierCompositeItemWriter 中获取资源名称

如何解决Spring Batch ResourceAware - 在 ClassifierCompositeItemWriter 中获取资源名称

我已经在我的域对象中实现了 ResourceAware 以在使用 MultiResourceItemReader 时设置资源名称。我能够成功地检索处理器中的资源名称。但是，在使用 FlatFileItemWriter 进行分类后，我无法访问 ClassifierCompositeItemWriter 中的资源名称，因为我无权访问域对象。任何帮助将不胜感激。

配置

 stepBuilderFactory.get("enrichmentStep")
.<recordtype,recordtype>chunk(1)
.reader(multiResourceItemReader())
.processor(processor())
.writer(compositeWriter())
.stream(type0Writer())
.stream(type1Writer())
.stream(type2Writer())

public ClassifierCompositeItemWriter compositeWriter() throws Exception {
  ClassifierCompositeItemWriter<recordtype> writer = new ClassifierCompositeItemWriter<>();
  SubclassClassifier classifier = new SubclassClassifier<>();
  Map typeMap = new HashMap<>();
  typeMap.put(recordtype0.class,type0Writer());
  typeMap.put(recordtype1.class,type1Writer());
  typeMap.put(recordtype2.class,type2Writer());
  classifier.setTypeMap(typeMap);
  writer.setClassifier(classifier);
  return writer;
}

@Bean
public FlatFileItemWriter<recordtype0> type0Writer() throws Exception{
  FlatFileItemWriter<recordtype0> writer = new FlatFileItemWriter<>();
  writer.setResource( new FileSystemResource("")); //To get the resource value from domain object here
  writer.setAppendAllowed(true);
  writer.setLineAggregator(new DelimitedLineAggregator<recordtype0>() {{
  setDelimiter("#");
  setFieldExtractor(new BeanWrapperFieldExtractor<recordtype0>() {{
  setNames(new String[] { "recordtype","BatchID","SubBatchID"});}});}});
   return  writer;
}
