我正在使用camel-azure-storage-blob移动azure blob存储中的文件。我正在尝试执行以下路由配置。

from(azurebloburi)
                        .process(getHeaders())
                        .log(LoggingLevel.INFO, log, "After adding Headers =${in.headers})")
                        .doTry()
                        .to(myapiendpoint)
                        .process(moveTheFile(SUCCESS_CONTAINER))
                        .toD(mysuccesscontaineruri-azure)
                        .doCatch(Exception.class)
                        .log(LoggingLevel.ERROR, log,
                                "Exception - Moving into ERROR.")
                        .process(moveTheFile(ERROR_CONTAINER))
                        .convertBodyTo(byte[].class)
                        .toD(myerrorcontainer-azure)
                        .end()

我在处理文件.toD(ERROR_CONTAINER)之前使用这些头设置。

exchange.getIn().setHeader(BlobConstants.BLOB_NAME, "changingBlobName");
                exchange.getIn().setHeader(BlobConstants.BLOB_OPERATION,BlobOperationsDefinition.uploadBlockBlob);
                exchange.getIn().setHeader(BlobConstants.BLOB_CONTAINER_NAME, "myexistingsourcelistener");

我得到了下面的错误。任何一种建议都将是有帮助的。

如果我正在删除.convertBodyTo(byte[].class)，则会出现以下错误。

在处理器BlobInputStream之前使用流缓存是一个经典的Java InputStream实现。

.log(LoggingLevel.ERROR, log,
                            "Exception - Moving into ERROR.")
                            .streamCaching()
                            .to("direct:test")
                            from("direct:test")
                    .process(moveTheFile(ERROR_CONTAINER))
                    .convertBodyTo(byte[].class)
                    .toD(myerrorcontainer-azure)
                    .end()
