Apache Camel Batch处理后如何移动文件？

Question

I bring a file from Amazon S3 and process it with Spring Batch, all integrated with Apache Camel.

After the batch, message body is not the file content anymore, it's de Job. But I want to move the file to another s3 bucket. How can I get the File content back? (I do have the headers)

(Using S3 is circumstantial)

        from("aws-s3://my-bucket...")
            .idempotentConsumer(header("CamelAwsS3Key"),
                  MemoryIdempotentRepository.memoryIdempotentRepository(200))
            .setHeader("CamelFileName", simple("${in.header.CamelAwsS3Key}"))
            .to("file:my-files/")
            .log("Copied from S3.")
            .to("spring-batch:historicoJob")
            .choice()
            .when(simple("${in.body.status} == 'COMPLETED'"))
            .to("direct:moveIt")
            .endChoice();

    from("direct:moveIt")
             ...
            .to("aws-s3://done-bucket...");

您可以访问原始消息（骆驼交换中有一些api->工作单元），也可以在春季批处理之前将消息主体复制到交换属性，然后再将其还原。
