Project: Camel
Issue Type: Bug
Affects Versions: 3.0.0
Reporter: Pascal Schumacher
https://camel.apache.org/components/latest/platform-http-component.html says:
{quote}The Platform HTTP is used to allow Camel to use the existing HTTP server
from the rumtime. For example when running Camel on Spring Boot...{quote}
But when I try to use the component e.g. with this simple route:
{code:java}
import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;
@Component
public class HelloRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
from("platform-http:/hello")
.setBody(constant("hello"));
}
}
{code}
start-up of the application fails with :
{code}
2019-11-30 13:17:02.953 ERROR 9648 --- [ restartedMain]
o.s.boot.SpringApplication : Application run failed
org.apache.camel.FailedToStartRouteException: Failed to start route route1
because of Route(route1)[From[platform-http:/hello] -> [SetBody[hello]]...

I do not see any way to fix this other than creating a custom
{{PlatformHttpEngine}} implementation. Am I missing something?
