Configure Route Recipients at run time

Hello,

I'm using camel 1.6.3 and would like to configure a route at runtime from a
unit test something like looking the endpoint up in memory by name, and
replacing the file:// by a mock:// ? I know I can override the
createroutebuilder in the unit test but I don't want to do this and also I
can't upgrade at the moment.

The route I'm actually trying to manipulate looks like this:
               Namespaces ns = new Namespaces("cps",
"http://www.bbc.co.uk/schemas/CPS/CPS-API/");
				
		from("seda:footballMatchCreateCPSAsset")
			.setHeader(FileComponent.HEADER_FILE_NAME,
					header(FOOTBALL_MATCH_ROOT_PATH_HEADER)
					.append("/create_cps_match_asset.xml"))
			.process(XsltBuilder.xslt(
					new
File("xslt/football/match/xml/football_match_create_cps_asset.xml.xslt")))
			.setBody(constant("payload=")
			.append(body()))			
			.setHeader(HttpMethods.HTTP_METHOD, constant(HttpMethods.POST))			
			.setHeader("Content-Type", constant("application/x-www-form-urlencoded"))
			.to(ConfigurationManager.getConfiguration().getString(
					"output.cpsapiWebService.createAssetUrl"))
			.to("seda:footballMatchSaveCPSAssetId");

I want to remove the last two to statements and add a to(mock:test)

I've been playing around with getting the route definitions from the context
but can't quite get it to work.

                List<RouteType> routeTypes =
testSupport.getContext().getRouteDefinitions();
		RouteType rt = routeTypes.get(31); //this is the route for
seda:footballMatchCreateCPSAsset
		
		List<ProcessorType<?>> outputs = rt.getOutputs();
		
		List<ProcessorType<?>> interceptorOutputs = outputs.get(0).getOutputs();
		interceptorOutputs.remove(5);
		interceptorOutputs.remove(5);
		//interceptor outputs actually look correct after the next line.
                outputs.get(0).addOutput(new ToType(new
MockEndpoint("mock:test"))); 

		//but rt is still showing the to:file in the pipeline so I did this, I'm
not sure what the difference between this and the above is but this adds
another interceptor to rt but doesn't appear to have any affect 		
		outputs.add(new ToType(new MockEndpoint("mock:test")));		
		
                rt.setOutputs(outputs);
		routeTypes.add(31, rt);

                MockEndpoint mock =
testSupport.getContext().getEndpoint("mock:test", MockEndpoint.class);
		mock.expectedMessageCount(1);        

		testSupport.sendBody("seda:footballMatchCreateCPSAsset",
FileUtils.readFileToString(
                new
File("testxml/football/matches/footballmatch_3003485.xml")));
                mock.assertIsSatisfied();

I think I'm going along the right lines although it looks like I need to get
at the recipient list for the route and modify that rather than the outputs?

Any help greatly appreciated.
Jon

yes.. you would extend the routbuilder class. So you could change the behaviour of the method that creates the route that starts with the direct endpoint.

The better way would probably be to have two direct endpoints and switch between them via a property.

Best regards

Thanks, I like the propery idea

When you say extend the routebuilder you mean the unit test will actually
extend the routebuilder?

eg) FootballMatchRouteBuilderTest extends FootballMatchRouteBuilder

Thanks

Hi Jon,

I would advise against changing the routes at runtime. How about introducing a direct endpoint and doing the last part of the route in a second method that can be changed for the test.

Like this:

from("seda:footballMatchCreateCPSAsset")
...
.to("direct:footballMatchEp")

Then in a separate method:

from("direct: footballMatchEp")
.to(ConfigurationManager.getConfiguration().getString(
					"output.cpsapiWebService.createAssetUrl"))
.to("seda:footballMatchSaveCPSAssetId");


Then in your test you can extend the routebuilder and replace the method with:

from("direct: footballMatchEp")
.to("mock:test")


An even better way than a separate method is using properties:
Add a property footballMatchEp to your route builder class and set this differently in the unit test (direct:footballMatchEpTest) and in the real app (direct:footballMatchEp). One for production use and one for tests.

Best regards

Christian
