> Key: CAMEL-20907
> URL: https://issues.apache.org/jira/browse/CAMEL-20907
> Project: Camel
> Issue Type: Bug
> Components: came-core
> Affects Versions: 3.18.0
> Reporter: kangjian
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.x
>
>
> Let's say I need to wait for an event notification and then pull an
> attachments email like this:
> Camel version 3.18.x
> {code:java}
> from("servlet://foo?servletName=MyServlet")
> .loopDoWhile().simple("${exchangeProperty.CamelBatchComplete} == null ||
> ${exchangeProperty.CamelBatchComplete} == false")
> .pollEnrich("imaps://{{mail.server}}?session=#oAuthSession&closeFolder=false&peek=true&folderName={{mail.sub.folder}}&sendEmptyMessageWhenIdle=true")
> .process(exchange -> {
> AttachmentMessage attachmentMessage = exchange.getIn(AttachmentMessage.class);
> // Here attachments is null
> Map<String, DataHandler> attachments = attachmentMessage.getAttachments();
> })
> .end();{code}
>
> Same code, works fine in Camel 3.14.x but doesn't work in Camel 3.18.x.
> After debugging, it was found that in Camel 3.16.x, the implementation of
> DefaultAttachmentMessage.java was upgraded.
> The key point is the CamelAttachmentObjects property in the ExchangeProperty,
> which is placed in the Exchange property in version 3.14.x, and in the
> ExtendedExchange property in version 3.16.x, which results in the loss of the
> CamelAttachmentObjects property between different Exchange.
> Details can be found in the link below line 274:
> [https://github.com/apache/camel/commit/0125a133a11cbdff57d459634bac276c10963387]
> I tried a solution as follows:
> Camel version 3.18.x
> {code:java}
> from("servlet://foo?servletName=MyServlet")
> .loopDoWhile().simple("${exchangeProperty.CamelBatchComplete} == null ||
> ${exchangeProperty.CamelBatchComplete} == false")
> .pollEnrich("imaps://{{mail.server}}?session=#oAuthSession&closeFolder=false&peek=true&folderName={{mail.sub.folder}}&sendEmptyMessageWhenIdle=true",
> ((oldExchange, newExchange) -> {
> // Deliver the attachment to the oldExchange
> oldExchange.setIn(newExchange.getIn(AttachmentMessage.class));
> return oldExchange;
> }))
> .process(exchange -> {
> AttachmentMessage attachmentMessage = exchange.getIn(AttachmentMessage.class);
> Map<String, DataHandler> attachments = attachmentMessage.getAttachments();
> })
> .end(); {code}
> The above can solve the problem of not being able to get attachments, but
> there will be other properties missing.
> Can you help with this? If information is missing, please do not hesitate to
> contact.
