Subject [jira] [Commented] (CAMEL-5503) Expanding Bean Binding annotations to define explicitly what to apply it to
Date Tue, 14 Aug 2012 09:29:38 GMT


Claus Ibsen commented on CAMEL-5503:

The embedded @Header annotation seems not ideally as its confusing, and people would mistake
that for a regular @Header annotation.

Is your use-case to execute a xpath on a header?

Instead maybe we could add an attribute on the annotations to refer to a header instead of
using the body as by default

@XPath("//baz/text()", header = "someHeader") String someValue

> It would be nice if you could specify what you want to apply it to; for instance you
could specify to apply it to headers/properties etc
> In terms of annotations it may look something like:
>     public void doSomething(@XPath("//foo/bar/text()", @Header("someHeader")) String
someValue) {
>     }
> For backwards compatability it would of course still apply to the body by default, but
we can still offer the ability to use it apply it explicitly ie
>     @XPath("//baz/text(), @Body) String someOtherValue
> I feel like this would be a useful addition to camel's bean binding.
> If anyone feels this is a good idea, I am offering to try it out and see how it goes
