Subject [jira] [Commented] (CAMEL-6194) Create @PreConsumed Annotation or Fix @Consumed Annotation For JPA Component
Date Thu, 28 Mar 2013 17:39:20 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-6194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13616461#comment-13616461
] 

Matt McCann commented on CAMEL-6194:
------------------------------------

Patch is now available. I'll write up some unit tests later this week.

I've added an @Preconsumed annotation that executes before the exchange is processed. This
annotation allows the resulting changes in the record due to being consumed to be visible
to components further down the route.

So what's the policy regarding dependencies? I added Google's guava library as a dependency
in the patch (Their "Optional" construct is awesome). It's released under the same license
as Camel.

> @Consumed functions are not called until after an exchange has been routed out of the
JPA component. Executing @Consumed functions is part of the stated functionality of the JPA
component so it seems logical that the @Consumed function should be called as part of routing
an exchange, not after the exchange has been routed.
> If possible, I think it'd be preferable to modify the @Consumed behavior though [~davsclaus]
has suggested the possible creation of an @PreConsumed annotation.
> I'm happy to implement this ticket this weekend if I can get some consensus on which
path is preferred by the community. This would be my first patch on the project so I figure
I ought not to run off on my own.
