public MessageRoutingCallback customRouter() {
return new MessageRoutingCallback() {
@Override
public FunctionRoutingResult routingResult(Message<?> message) {

In the preceding example you can see a very simple implementation of `MessageRoutingCallback` which determines the function definition from
`func_name` Message header of the incoming Message and returns the instance of `FunctionRoutingResult` containing the definition of function to invoke.
`FunctionProperties.FUNCTION_DEFINITION` Message header of the incoming Message and returns the instance of `String` representing the definition of function to invoke.
