Description
When redelivery occurs for dynamic routers, the properties are being kept. So if the dynamic router uses a property to store the current state such as used in example http://camel.apache.org/dynamic-router.html , then the redelivery actually ends up skipping the endpoint that caused the exception
Here is my dynamic router class
public class Router {
public String route(Exchange exchange) {
Boolean invoked = exchange.getProperty("invoked", Boolean.class);
if (invoked == null) {
exchange.setProperty("invoked", true);
return "mock:route";
} else
return null;
}
}
Here is my unit test class
@RunWith(CamelSpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = CamelSpringDelegatingTestContextLoader.class)
public class DynamicRouterTest {
@Produce(uri = "direct:start")
private ProducerTemplate producerTemplate;
@EndpointInject(uri = "mock:end")
private MockEndpoint end;
@EndpointInject(uri = "mock:route")
private MockEndpoint route;
@Configuration
public static class JavaConfig extends SingleRouteCamelConfiguration {
@Override
public RouteBuilder route() {
return new SpringRouteBuilder() {
@Override
public void configure() throws Exception {
this.getContext().setTracing(true);
from("direct:start").onException(IOException.class).maximumRedeliveries(-1).end()
.dynamicRouter().method(Router.class).to("mock:end");
}
};
}
}
@Test
public void test() throws InterruptedException {
route.whenAnyExchangeReceived(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getIn().setBody("mock route");
}
});
route.expectedBodiesReceived("before");
end.expectedBodiesReceived("mock route");
producerTemplate.sendBody("before");
route.assertIsSatisfied();
end.assertIsSatisfied();
}
@Test
public void test_exception() throws InterruptedException {
route.whenExchangeReceived(1, new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.setException(new IOException());
}
});
route.whenExchangeReceived(2, new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getIn().setBody("mock route");
}
});
// this bit fails
route.expectedBodiesReceived("before", "before");
end.expectedBodiesReceived("mock route");
producerTemplate.sendBody("before");
route.assertIsSatisfied();
end.assertIsSatisfied();
}
}
The test method runs successfully but the test_exception method which tests the redelivery does not. Fails with "java.lang.AssertionError: mock://route Received message count. Expected: <2> but was: <1>" which shows that the dynamic router only called the mock:route once.
