Is it possible to change elements in json request dynamically ?

Issue

• REST DSL how do I set the property naming strategy in the rest configuration dataformat section of my camel context
• My com.mycompany.Test pojo has a field name firstName with getter and setter. But my json has first_name.
• Following is the stacktrace.
