Spring Batch：如何创建复合项目编写器？

下面的代码在我的情况下有效。

这是我的作家1：

@Componentpublic class Writer1 implements ItemStreamWriter<SimpleObject>,org.springframework.batch.item.ItemWriter<SimpleObject>  {    @Override    public void write(List<? extends SimpleObject> list) throws Exception {        for(SimpleObject simpleObject: list){ // some logic }        }    }    @Override    public void open(ExecutionContext executionContext) throws ItemStreamException {    }    @Override    public void update(ExecutionContext executionContext) throws ItemStreamException {    }    @Override    public void close() throws ItemStreamException {    }}

这是我的作家2：

@Componentpublic class Writer2 implements ItemStreamWriter<SimpleObject>, org.springframework.batch.item.ItemWriter<SimpleObject>  {    @Override    public void write(List<? extends SimpleObject> list) throws Exception {        for(SimpleObject simpleObject: list){// some logic         }    }    @Override    public void open(ExecutionContext executionContext) throws ItemStreamException {    }    @Override    public void update(ExecutionContext executionContext) throws ItemStreamException {    }    @Override    public void close() throws ItemStreamException {    }}

在这里，我试图初始化

Tasklet

CompositeItemWriter

CompositeItemWriter<SimpleObject> compositeItemWriter = new CompositeItemWriter<>();     List<org.springframework.batch.item.ItemWriter<? super SimpleObject>> delegates = new ArrayList<>();     delegates.add(writer1);     delegates.add(writer2);     compositeItemWriter.setDelegates(delegates);     TaskletStep processingStep = stepBuilderFactory.get(getLabel() + "-" + UUID.randomUUID().toString())  .<SimpleObject, SimpleObject>chunk(5)  .reader(reader)  .processor(processor)  .writer(compositeItemWriter)  .stream(writer1)  .stream(writer2)  .transactionManager(txManager)  .build();

请让我知道我是否错过了任何内容或信息不正确。
