How to use @Transformer bean with Spring Java DSL integration?

Question

I would like to use a bean using a method annotated with @Transformer to transform a message accessing part of its headers using the @Header annotation. Is there a way to do this using Java DSL (with Java 7, so there is no lambdas)? This is not like that.

Answer 1

You can do it as follows:

.handle("myTransformer", "myMethod")

if your transformer does not return Message.

On the other hand, if you are already using @Transformer, you can add attributes channelto create a real endpoint for this method and use these channels from IntegrationFlow, for example..gateway("transformChannel")
