Jussi Nupponen created CAMEL-9866:
-------------------------------------
Summary: @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: 2.17.0, 2.16.3
Reporter: Jussi Nupponen
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}

{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:
