Adding custom headers to messages

[keidi19]

Hi,

I have a general question regarding headers: what are the ways to add custom headers to a message?
The ones I know of:

1. Header enricher: good only for adding headers with static values?
2. Transformer: I'm using a transformer bean with a single method that accepts the Message interface. This is nice, but too coupled to Spring.

Are there any other ways?

The header-enricher now supports any expression to be evaluated against the Message as well, so it should be sufficient. Simply add 'expression' rather than 'value'.

Hope that helps.

Thanks Mark!

It's good to know that the header enricher supports dynamic values as well.
Is it possible to map method arguments (let say of a gateway interface) to the payload/header using annotations or something of that sort?

Thanks.

[Mark Fisher]

Yes, the gateway supports @Payload and @Header annotations on method-arguments. The @Payload can even contain an expression to be evaluated against the annotated argument.

Thanks! I'll check that out.

Works perfect! Thanks again.
