我首先有多部分文件，我想将其发送到骆驼管道并使用原始名称保存该文件。

我的代码：

@Autowired
ProducerTemplate producerTemplate;
...
      producerTemplate.sendBody("seda:rest_upload", multipartFile);

在另一边我有：

from("seda:rest_upload").convertBodyTo(File.class).to("file://rest_files");

我还尝试注册转换器：

@Converter
public class MultiPartFileToFileConvertor {
    @Converter
    public static File toFile(MultipartFile multipartFile) throws IOException {
        File convFile = new File(multipartFile.getOriginalFilename());
        multipartFile.transferTo(convFile);
        return convFile;
    }
}

当我执行代码时，我看到以下堆栈跟踪：
