How do I use a @Transformer bean with Spring Integration Java DSL?

I'd like to use a bean with a method annotated with @Transformer to transform a message accessing part of its headers with the @Header annotation. Is there a way to do this with the Java DSL (with Java 7, so no lambdas)? It does not seem like so.

You can do it like this:

.handle("myTransformer", "myMethod")

if your transformer doesn't return Message.

From other side, if you already use @Transformer there you can add channel attributes to make the real endpoint for that method and use those channels from the IntegrationFlow, e.g. .gateway("transformChannel")

Since 1.1 we are going to add more EIP-methods to make it more flexible for similar cases.

Feel free to raise GH issue on the matter!

This...

.transform("@transformerBean.someMethod(payload, headers['foo'])")

...should work.
