推荐答案

FlatFileItemWriter 旨在将项目写入平面文件或表示文件的可写 Resource.这是其 Javadoc:

The FlatFileItemWriter is designed to write items to a flat file or a writable Resource that represents a file. Here is an excerpt from its Javadoc:

The location of the output file is defined by a Resource and must represent a writable file.

因此，在您的情况下，您需要使用将项目写入内存资源的自定义编写器.

So in your case, you need to use a custom writer that writes items to an in-memory resource.
