Tomas Rohovsky reassigned CAMEL-9866:
-------------------------------------
Assignee: Tomas Rohovsky
> @PropertyInject doesn't work with Spring-Boot
> ---------------------------------------------
>
> Key: CAMEL-9866
> URL: https://issues.apache.org/jira/browse/CAMEL-9866
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.16.3, 2.17.0
> Reporter: Jussi Nupponen
> Assignee: Tomas Rohovsky
>
> When I upgraded Camel Spring-Boot project to use Camel 2.16.3 from Camel
> 2.16.2 the @PropertyInject annotations broke.
> The problem occurs when using the annotation in a Spring-Boot application
> like this
> {code:java}
> @SpringBootApplication
> public class MySpringBootRouter extends FatJarRouter {
> @PropertyInject("inject-value")
> private String injectedValue;
>
> @Override
> public void configure() {
> from("timer:trigger")
> .log("PropertyInject: "+injectedValue);
> }
> }
> {code}
> Running the code above with command
> {noformat}
> mvn spring-boot:run
> {noformat}
> causes the following exception:
> {noformat}

> Using placeholders like {noformat}.log("{{inject-value}}"){noformat} still
> works just as before. I tried to browse through changes between 2.16.2 and
> 2.16.3 but I didn't catch any obvious reason for this problem.
> I created a runnable demo of the problem here:
> https://github.com/jnupponen/camel-properties-component-spring-boot-problem
