Issue setting property on the object which in the exchange body

[gilboy <jo...@gmail.com>]

Hi 

In my route, I have a header property on the exchange called age. In the
body of the exchange I have a person object. I want to set the age property
on the person object.

If I do something like the following in my route and have the setAge
property on the Person bean use the header annotation(e.g.
setAge(@Header("age")Integer age)) the property will get correctly set.
However, the setter message is void, hence the body on the exchange gets
wiped. I can have the setter method return "*this*" but it feels wrong

    <transform>
      <simple>${body.setAge}</simple>
    </transform>

Any other solution?
Thanks
Joe

You can use the bean method return the message body just like this

public class Bar {
 
    @Handler
    public Foo doSomething(@Header("age")Integer age, @Body Foo foo) {
        foo.setAge(age);
	return foo;
   }

from("activemq:someQueue").
  bean(Bar.class);

You can find more information about Bean Binding here[1]
