Spring Boot + Camel + JPA not working in Fabric8

[Benjamin Fayle]

Has anyone managed to get Spring Boot + Camel + JPA working in Fabric8?

I made a simple app based on the Fabric8 Spring Boot Camel example but added JPA support.

If I comment out the annotations @EnableJpaRepositories and @EntityScan then Fabric8 no longer sees this as a Camel route.

I can't find anything in Fabric8 or Hawtio that explains what is going on. 

package io.fabric8.quickstarts.camel;

import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.orm.jpa.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@Configuration
//@EnableJpaRepositories
//@EntityScan
public class CamelConfiguration {

    @Bean
    RouteBuilder routeBuilder() {
        return new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("timer://foo?fixedRate=true&period=5000").
                        setBody().constant("<hello>world!</hello>").
                        log(">>> ${body}");
            }
        };
    }

    // Collaborators fixtures
    @Autowired
    CamelContext camelContext;

}

I'm using this for the pom.xml:

Hi

I will take a look at your example after the weekend. Stay tuned :-)

Cheers.

Hi Benjamin,

>> Has anyone managed to get Spring Boot + Camel + JPA working in Fabric8?

Can you attach your Maven project here? I'm not sure if I get the
issue you have here. Can you make the project to fail on 'mvn clean
install'?

Cheers.

The project doesn't  fail on that. It's when you deploy it to Fabric8 using mvn fabic8:deploy. It deploys successfully but If you look at the container created in hawtio it recognizes the Camel route with the lines commented. Comment them out and it no longer recognizes the Camel route.
