Stefano Rocca updated CAMEL-17516:
----------------------------------
Description:
While setting up a route template, if you use a parameter named like an
environment variable, camel resolves first the environment variable and ignores
the value of the parameter set using the TemplateRouteBuilder.
Here follows a short program that exhibit this behaviour (this code is also
attached to this issue as "sample_code.txt")
import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.builder.TemplatedRouteBuilder;
import org.apache.camel.main.ConfigureRouteTemplates;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Main {
public static final Logger LOG = LoggerFactory.getLogger(Main.class);
public static class MyRouteBuilder extends RouteBuilder {
public void configure() throws Exception {
routeTemplate("myTemplate")
.templateParameter("name")
.templateParameter("path")
.templateParameter("myPeriod", "3s")
.from("timer:{{{{{}name{}}}}}?period={{{{{}myPeriod{}}}}}")
.log("{{{{{}path{}}}}}");
}
}
public static class MyTemplateBuilder implements ConfigureRouteTemplates {
public void configure(CamelContext context) {
TemplatedRouteBuilder.builder(context, "myTemplate")
.parameter("name", "one")
.parameter("path", "test path")
.add();
}
}
public static void main(String[] args) throws Exception
{ org.apache.camel.main.Main m = new org.apache.camel.main.Main();
m.configure().addRoutesBuilder(MyRouteBuilder.class);
m.bind("myTemplateBuilder", new MyTemplateBuilder()); m.run(args); }
}
This sample code, when run with Camell 3.11.1 or 3.11.5, outputs the content of
the PATH variable.
If you run it with Camel 3.14.0, it outputs "test path".
