Camel ActiveMQ + Spring boot not reading spring activemq configurations

Question

I am trying a very simple route with Spring Boot 1.5.2.RELEASE + Camel (Spring Boot Starter) + ActiveMQ, which is to read from a particular queue and then log it. However, it looks like it is not picking up my spring.activemq configuration for URL as I see in the log it is trying to connect to a different url and it continues to connect it and the my spring boot app never starts. The questions are based on my configuration that I am providing below how can I do the below:

1. Fix the configuration to allow spring's activemq configuration
2. Configure maxReconnectAttempts so that it does not try to connect forever if the URL is not reachable, which could be possible if the ActiveMQ instance goes down

Any assistance would be greatly appreciated. I did search relevant questions on stackoverflow but none gave me a solution to the issue I am facing

Error I am seeing on the console and this continues to like 60-70 attempts and counting. As you can see the broker URL that camel is picking up is some default URL that probably spring has configured by default

Failed to connect to [tcp://localhost:61616] after: 10 attempt(s) continuing to retry.

Here are my current configurations / code:

Camel Route in JAVA

import org.springframework.stereotype.Component;

@Component
public class SampleAmqCamelRouter extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("activemq:some.queue").to("log:com.mycamel.route?level=INFO&groupSize=10");
    }

First you should add the spring-boot-starter-activemq dependency to your pom.xml. Then you can use its AutoConfiguration capabilities which will create a ConnectionFactory based on the properties you have specified in your application.yml.

After that you have to configure Camel's ActiveMQComponent too. If you would like to reuse the ConnectionFactory (which created by the autoconfig) then it can be achievable with the following:

@Configuration
public class ActiveMQComponentConfig {

    @Bean(name = "activemq")
    public ActiveMQComponent createComponent(ConnectionFactory factory) {
        ActiveMQComponent activeMQComponent = new ActiveMQComponent();
        activeMQComponent.setConnectionFactory(factory);
        return activeMQComponent;
    }
}

You can find more information in Camel's ActiveMQ documentation.
