Zoran Regvart commented on CAMEL-11476:
---------------------------------------
I've found the issue and a possible solution, I'm running tests to see if the
solution caused any other issues.
The problem is that the equality check in
[RoutesCollector.java#L81|https://github.com/apache/camel/blob/master/components/camel-spring-boot/src/main/java/org/apache/camel/spring/boot/RoutesCollector.java#L81]
does not pass when {{management.port=8081}} is set. And this in turn is
because
[EndpointWebMvcAutoConfiguration.java#L144|https://github.com/spring-projects/spring-boot/blob/master/spring-boot-actuator/src/main/java/org/springframework/boot/actuate/autoconfigure/EndpointWebMvcAutoConfiguration.java#L144]
instantiates a new {{ApplicationContext}} instance if the management port is
customized.
So previously {{RoutesCollector} would start {{CamelContext}} but now
{{CamelContext}} is started by {{ContextRefreshedEvent}}, and it is started on
the first {{ContextRefreshedEvent}} for the first {{ApplicationContext}}, and
as {{RoutesCollector}} checks if its a part of that {{AppplicationContext}} it
won't add {{RouteBuilders}}, and the second {{ContextRefreshedEvent}} from the
second {{ApplicationContext}} does not load any {{RouteBuilders}} as at that
point {{CamelContext}} is already started and the second check in
[RoutesCollector.java#L86|https://github.com/apache/camel/blob/master/components/camel-spring-boot/src/main/java/org/apache/camel/spring/boot/RoutesCollector.java#L86]
will not pass.
> spring-boot - routes not loaded when setting a management.port

> Key: CAMEL-11476
> URL: https://issues.apache.org/jira/browse/CAMEL-11476
> Project: Camel
> Issue Type: Bug
> Components: camel-spring-boot
> Affects Versions: 2.20.0
> Reporter: Nicola Ferraro
> Assignee: Zoran Regvart
> Fix For: 2.20.0
>
>
> This is a really weird bug. If you set:
> {code}
> management.port=8081
> {code}
> On the application.properties file of any spring-boot application using
> actuator, then camel routes created through RouteBuilders are not loaded
> ("Total 0 routes, of which 0 are started.").
> I've found it in (all) the fabric8 basic quickstarts, but it happens also in
> the "camel-example-spring-boot" bundled with Apache Camel. Everything works
> in 2.19.x.
> Setting a different management port is a best practice.
> [~zregvart], [~cib...@e-ma.net], [~lb] any idea?
