Route.java

 @Component
 public class Route extends RouteBuilder {  

     @Override
     public void configure() throws Exception {
         from("rabbitmq:{{core.consumer.rabbitmq.exchange}}" +
             "?exchangeType={{core.consumer.rabbitmq.exchange-type}}" +
             "&queue={{core.consumer.rabbitmq.queue}}" +
             "&routingKey={{core.consumer.rabbitmq.routing-key}}")
             .routeId("queue route")
             .log("Received payload from rabbitMQ: ${body}")
             .unmarshal(new JacksonDataFormat(Dto.class))
             .process(aProcessor)
             .log("Data received ${body}")
             .to("bean:requestProcessor?method=handleAckRequest").id("handle-ack-request")
  
             .to("direct:anotherRoute")
         .end();
     }
 }

In the application.properties
camel.springboot.log-mask=true
 
Now if I should post the following JSON payload through RabbitMQ
