只需编写一个自定义的ItemWriter即可.

Just write a custom ItemWriter that does exactly that.

public class YourItemWriter implements ItemWriter<CompositeClaimRecord>` {

  private final ItemWriter<Record1> writer1;
  private final ItemWriter<Record2> writer2;

  public YourItemWriter(ItemWriter<Record1> writer1, ItemWriter<Record2> writer2>) {
    this.writer1=writer1;
    this.writer2=writer2;
}

  public void write(List<CompositeClaimRecord> items) throws Exception {

    for (CompositeClaimRecord record : items) {
       writer1.write(Collections.singletonList(record.claimRecord1));
       writer2.write(Collections.singletonList(record.claimRecord2));

    }
  }
}

或者不是一次写入1条记录，而是将单个列表转换为2个列表并将其传递.但是以这种方式，错误处理可能会有点挑战. \

Or instead of writing 1 record at a time convert the single list into 2 lists and pass that along. But error handling might be a bit of a challenge that way. \

public class YourItemWriter implements ItemWriter<CompositeClaimRecord>` {

  private final ItemWriter<Record1> writer1;
  private final ItemWriter<Record2> writer2;

  public YourItemWriter(ItemWriter<Record1> writer1, ItemWriter<Record2> writer2>) {
    this.writer1=writer1;
    this.writer2=writer2;
}

  public void write(List<CompositeClaimRecord> items) throws Exception {

    List<ClaimRecord1> record1List = items.stream().map(it -> it.claimRecord1).collect(Collectors.toList());
    List<ClaimRecord2> record2List = items.stream().map(it -> it.claimRecord2).collect(Collectors.toList());

    writer1.write(record1List);
    writer2.write(record2List);


  }
}
