Getting closer:
import org.apache.camel.Exchange
import org.apache.camel.Processor
import org.apache.camel.Message
class JobRoute {
def configure = {
println "Setting JobRoute Camel Router..."
from("seda:my.queue") {
Exchange exchange =
template.send("http://localhost:4567/jodmock";,
[
process: { exchange ->
exchange.getIn().setHeader(Exchange.HTTP_METHOD,
constant(POST));
}
] as Processor
);
Message out = exchange.getOut();
int responseCode =
out.getHeader(HttpProducer.HTTP_RESPONSE_CODE, Integer.class);
}
}
}
Produces:
Caused by: groovy.lang.MissingMethodException: No signature of method:
org.ix.grails.plugins.camel.GrailsRouteBuilder.from() is applicable for
argument types: (java.lang.String, JobRoute$_closure1_closure2) values:
[seda:my.queue, jobroute$_closure1_closu...@55661f7b]
Run-time error, so we're past the compilation problem. I guess it doesn't
like the second closure. :)
Thanks for the help. Still curious about how to the get the my.queue
message into the body of the In's POST.
