Subject [jira] [Commented] (CAMEL-4565) Allow to send messages using a user supplied pojo interface
Date Sat, 22 Oct 2011 07:00:32 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-4565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13133282#comment-13133282

Christian Schneider commented on CAMEL-4565:
--------------------------------------------

The ProxyHelper seems to always create a BeanInvocation. So I think we are not already there.
I now work out a prototype of a InvocationHandler for
pojo messaging.

> The basic requirement is that we want to send a user defined object to a camel endpoint.
The user code for sending the object should not contain any camel code.
> So imagine a simple DTO like Person with properties name and age. I would like to use
an interface like
> interface PersonSender {
>   void send(Person person);
> }
> So in the use code I code get an implementation injected that I simply could call with

> sender.send(person);
> So this is quite similar to our Pojo Messaging @Produce but I donĀ“t want to send a BeanInvocation.
Instead I would like to just have the Person object in the body. Ideally this should also
support request / response if there is a return type.
> Additionally it should be configurable if it should send aynschronously or synchronously.
> Optionally we may also support a handler or Future for the response.
> To get the interface implementation we should support up to three variants.
> 1) Create the dynamic proxy programmatically
> 2) Define the proxy thiough a spring bean
> 3) Create and inject the proxy using the @Produce annotation (we will need a flag to
switch behaviour or use a second annotation)
