2 years ago IMHO, camel-bridge is broken in vertx v4.x. The following does not work
public void testCamelBridge() throws Exception {
CamelContext camelContext = new DefaultCamelContext();
camelContext.addRoutes(new RouteBuilder() {
@Override
public void configure() {
from("direct:start").transform(constant("OK"));
}
});
camelContext.start();
VertxOptions vertxOptions = new VertxOptions();
vertxOptions.setEventLoopPoolSize(4);
vertxOptions.setWorkerPoolSize(4);
Vertx vertx = Vertx.vertx(vertxOptions);
CamelBridge bridge = CamelBridge.create(vertx, new CamelBridgeOptions(camelContext)
.addOutboundMapping(OutboundMapping.fromVertx("test").toCamel("direct:start")));
bridge.start();
vertx.eventBus().request("test", "hello", reply -> LOG.info("reply.result().body():{}"
, reply.result() != null ? reply.result().body() : "null"));
}
Executing the method will trace INFO reply.result().body():null while when running in vertx v3.x (replace vertx.eventBus().request( ... ) with vertx.eventBus().send( ... )) it will trace INFO reply.result().body():OK as expected.
In vertx v4.x I'm having camel v3.x and vertx v3.x camel v2.x if that matters.
