Camel: AWS -S3: тело файла null, при использовании файла из s3 и переходе в Rest api

0 голосов
/ 02 августа 2020

При выполнении Camel AWS Потребитель S3 для чтения файлов из S3 и передачи их в конечную точку Rest завершается ошибкой, поскольку тело файла становится нулевым. Я использовал аналогичный код для использования файла из sftp, он работал. Но когда я использую конечную точку Aws, это не удается. Есть ли какие-либо другие настройки для объекта обмена s3?

Тело файла становится нулевым при использовании файла из s3 и передаче его в Rest API.

Код: 

from("aws-s3://test?amazonS3Client=#amazonS3Client&deleteAfterRead=false&delay=5000&synchronous=true&includeBody=true&autocloseBody=false&exchangePattern=InOut")
                   .convertBodyTo(byte[].class)
                    .log(LoggingLevel.INFO, "consuming", "Consumer Fired!")
                    .log(LoggingLevel.INFO, "Replay Message Sent to file:s3out ${in.header.CamelAwsS3Key}")
                    .filter(simple("${in.header.CamelAwsS3Key} contains 'score_input'"))
                   // .to("file:target/s3out?fileName=${in.header.CamelAwsS3Key}")
                    .process(new Processor() {
                        @Override
                        public void process(Exchange exchange) throws Exception {
                            MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
                            String filename = exchange.getIn().getHeader(Exchange.FILE_NAME, String.class);
                            File file = exchange.getIn().getBody(File.class);
                            multipartEntityBuilder.addPart("file",
                                    new FileBody(file, ContentType.MULTIPART_FORM_DATA, filename));
                            exchange.getOut().setBody(multipartEntityBuilder.build());
                        }
                    })
                    .to(httpRoute)
