try this:
class JobRoute extends RouteBuilder {
void 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(org.apache.camel.component.http.HttpMethods.POST));
}
] as Processor
);
Message out = exchange.getOut();
int responseCode =
out.getHeader(HttpProducer.HTTP_RESPONSE_CODE, Integer.class);
}
}
