Henryk Konsek commented on CAMEL-8482:
--------------------------------------
Actually I think that this is a different issue than CAMEL-8460. I need to take
a look at Spring Cloud before I investigate it. Added to my backlog.
> Camel requires restart of Spring applicationcontext to fetch new values for
> properties managed by Spring Cloud

> Key: CAMEL-8482
> URL: https://issues.apache.org/jira/browse/CAMEL-8482
> Project: Camel
> Issue Type: Bug
> Components: camel-spring-boot
> Affects Versions: 2.15.0
> Reporter: Manuel Rivas
> Assignee: Henryk Konsek
> Attachments: config-client.zip
>
>
> When having a camel route builder making use of a property managed by spring
> cloud config server, the beans in the application managed by Spring get the
> property values refreshed when invoking the Spring cloud config
> RefreshEndpoint but the camel routebuilders does not pick up the new values.
> Restarting the camel context does not help either. Restart of Spring
> application context is required.
> Example that works for Spring managed beans:
> package se.comhem.service;
> import org.springframework.beans.factory.annotation.Value;
> import org.springframework.cloud.context.config.annotation.RefreshScope;
> import org.springframework.stereotype.Component;
> @Component
> @RefreshScope()
> public class CosmosProperties {
> @Value("${cosmos.someappconf}")
> private String someAppConf;
> public String getSomeAppConf(){
> return someAppConf;
> }
> }
> When using this bean together with a camel routebuilder it does not work
> until Spring Application context is restarted:
> package se.comhem.service;
> import org.apache.camel.model.language.SimpleExpression;
> import org.apache.camel.spring.SpringRouteBuilder;
> import org.springframework.beans.factory.annotation.Autowired;
> import org.springframework.stereotype.Component;
> @Component
> public class ConfigClientRouteBuilder extends SpringRouteBuilder {
> private final static String URI = "servlet:///testCamel";
> @Autowired
> private CosmosProperties cosmosProperties;
> @Override
> public void configure() throws Exception {
> from(URI)
> .setBody(new
> SimpleExpression(cosmosProperties.getSomeAppConf()))
> .to("log:se.comhem?level=INFO&showBody=true&multiline=true")
> .end();
> }
> }
