                .when(bodyAs(String.class).contains("INFO"))
                    .process(new MyProcessor())
                    .marshal().json(JsonLibrary.Jackson)
                    .to("file:data/outputFolder?fileName=info.json&fileExist=Append")

                .when(bodyAs(String.class).contains("DEBUG"))
