Hello !
I'm trying to experiment with the new route templates features along with
spring boot.
I just tried to create a class with both the template and the route provided in
the camel page https://camel.apache.org/manual/latest/route-template.html:
I'm using Camel 3.5 and springboot 2.3.4
@Component
public class MyRouteTemplates extends RouteBuilder {
@Override
public void configure() throws Exception {
// create a route template with the given name
routeTemplate("myTemplate")
// here we define the required input parameters (can have
default values)
.templateParameter("name")
.templateParameter("greeting")
.templateParameter("myPeriod", "3s")
// here comes the route in the template
// notice how we use {{name}} to refer to the template
parameters
// we can also use {{propertyName}} to refer to property
placeholders
.from("timer:{{name}}?period={{myPeriod}}")
.setBody(simple("{{greeting}} ${body}"))
.log("${body}");
TemplatedRouteBuilder.builder(getContext(), "myTemplate")
.routeId("myCoolRoute")
.parameter("name", "one")
.parameter("greeting", "Hello")
.add();
}
}
When I run "mvn spring-boot:run", I got an error saying that the template
cannot be found.
java.lang.IllegalArgumentException: Cannot find RouteTemplate with id myTemplate

Is there something wrong with what I'm trying to achieve ?
Thanks in advance for your help ! :)
