Getting the exception 'Cannot find any routes with this RouteBuilder reference: RouteBuilderRef[routebuilderOne]'

Question

I am getting the exception Cannot find any routes with this RouteBuilder reference: RouteBuilderRef[routebuilderOne] when I am trying to wire the route builder based on configuration.

Class file of Route Builder 1

import org.apache.camel.spring.SpringRouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class RoutebuilderOne extends SpringRouteBuilder {
     @Value("${routebuilder.stream.one}")
     private boolean                 autoStartupRouteOne;

     @Override
     public void configure() throws Exception {
          from(source1).autoStartup(autoStartupRouteOne).split().method("splitLogic","splitMethod").to(destination1);

     }
}

Class file of Route builder 2

import org.apache.camel.spring.SpringRouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class RoutebuilderTwo extends SpringRouteBuilder {
     @Value("${routebuilder.stream.two}")
     private boolean                autoStartupRouteTwo;

     @Override
     public void configure() throws Exception {
        from(source2).autoStartup(autoStartupRouteTwo).to(destination2);

     }
}

Camel context file

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
   http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context.xsd
   http://camel.apache.org/schema/spring 
   http://camel.apache.org/schema/spring/camel-spring.xsd">

   <camelContext xmlns="http://camel.apache.org/schema/spring">
       <routeBuilder ref="routebuilderOne"/>
       <routeBuilder ref="routebuilderTwo"/>
   </camelContext>

   <context:component-scan
    base-package="com.hurix.routebuilders" />
 </beans>

Values for autoStartupRouteOne,autoStartupRouteTwo as in the property file

 autoStartupRouteOne = false
 autoStartupRouteTwo = true

Is there any other way to achieve the conditional based route selection ?

Answer 1

You need to give the @Component a id, and not use the class name as the id. A java class name should start with upper case.

Not sure if the spring annotation can do that, but maybe you can do @Component(name = "routebuilderOne") or something.
