I am trying to intercept a message to skip the Http request and proceed with my route.
Below is the class you can copy/paste to try it out.
Using camel-test, camel-core, camel-http4 2.10.2 and httpclient-osgi, httpcore-osgi 4.2.2
Here is the code :
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.builder.AdviceWithRouteBuilder;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.test.junit4.CamelTestSupport;
import org.junit.Test;
/**

public class IsUseAdviceWithJUnit4Test extends CamelTestSupport {
private String providerEndPointURI = "http://stackoverflow.com";
private String timerEndPointURI = "timer://myTimer";
private String mockEndPointURI = "mock:myMock";
private String directEndPointURI = "direct:myDirect";
private boolean messageIntercepted;
#Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
#Override
public void configure() throws Exception {
from(timerEndPointURI + "?fixedRate=true&delay=1000&period=1000")
.to(providerEndPointURI + "?throwExceptionOnFailure=false")
.to(mockEndPointURI);
}
};
}
#Test
public void testIsUseAdviceWith() throws Exception {
messageIntercepted = false;
context.getRouteDefinitions().get(0).adviceWith(context, new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
replaceFromWith(directEndPointURI);
mockEndpoints();
interceptSendToEndpoint(providerEndPointURI)
.skipSendToOriginalEndpoint()
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {
messageIntercepted = true;
System.out.println("INTERCEPTED");
}
});
}
});
// we must manually start when we are done with all the advice with
context.start();
getMockEndpoint(mockEndPointURI).expectedMessageCount(1);
template.sendBody(directEndPointURI, "a trigger");
assertMockEndpointsSatisfied();
assertEquals(true, messageIntercepted);
assertNotNull(context.hasEndpoint(directEndPointURI));
assertNotNull(context.hasEndpoint("mock:" + directEndPointURI));
assertNotNull(context.hasEndpoint(mockEndPointURI));
}
#Override
public boolean isUseAdviceWith() {
return true;
}
#Override

return true;
}
}
Thank you for your help !

I am trying to test my Camel Routes using CamelTestSupport. I have my routes defined in a class like this
public class ActiveMqConfig{
#Bean
public RoutesBuilder route() {
return new SpringRouteBuilder() {
#Override
public void configure() throws Exception {
from("activemq:{{push.queue.name}}").to("bean:PushEventHandler?method=handlePushEvent");
}
};
}
}
And my test class look like this
#RunWith(SpringRunner.class)
public class AmqTest extends CamelTestSupport {
#Override
protected RoutesBuilder createRouteBuilder() throws Exception {
return new ActiveMqConfig().route();
}
#Override
protected Properties useOverridePropertiesWithPropertiesComponent() {
Properties properties = new Properties();
properties.put("pim2.push.queue.name", "pushevent");
return properties;
}
protected Boolean ignoreMissingLocationWithPropertiesComponent() {
return true;
}
#Mock
private PushEventHandler pushEventHandler;
#BeforeClass
public static void setUpClass() throws Exception {
BrokerService brokerSvc = new BrokerService();
brokerSvc.setBrokerName("TestBroker");
brokerSvc.addConnector("tcp://localhost:61616");
brokerSvc.setPersistent(false);
brokerSvc.setUseJmx(false);
brokerSvc.start();
}
#Override
protected JndiRegistry createRegistry() throws Exception {
JndiRegistry jndi = super.createRegistry();
MockitoAnnotations.initMocks(this);
jndi.bind("pushEventHandler", pushEventHandler);
return jndi;
}
#Test
public void testConfigure() throws Exception {
template.sendBody("activemq:pushevent", "HelloWorld!");
Thread.sleep(2000);
verify(pushEventHandler, times(1)).handlePushEvent(any());
}}
This is working perfectly fine. But I have to set the placeholder {{push.queue.name}} using useOverridePropertiesWithPropertiesComponent function. But I want it to be read from my .yml file.
I am not able to do it. Can someone suggest.
Thanks
Properties are typically read from .properties files. But you can write some code that read the yaml file in the useOverridePropertiesWithPropertiesComponent method and put them into the Properties instance which is returned.
Thank Claus.
I got it working by doing this
#Override
protected Properties useOverridePropertiesWithPropertiesComponent() {
YamlPropertySourceLoader loader = new YamlPropertySourceLoader();
try {
PropertySource<?> applicationYamlPropertySource = loader.load(
"properties", new ClassPathResource("application.yml"),null);
Map source = ((MapPropertySource) applicationYamlPropertySource).getSource();
Properties properties = new Properties();
properties.putAll(source);
return properties;
} catch (IOException e) {
LOG.error("Config file cannot be found.");
}
return null;
}
I am trying to test a Camel route (polling messages from an SQS queue) containing
.bean("messageParserProcessor")
where messageParserProcessor is a Processor.
The test:
public class SomeTest extends CamelTestSupport {
private final String queueName = ...;
private final String producerTemplateUri = "aws-sqs://" + queueName + ...;
private static final String MESSAGE_PARSER_PROCESSOR_MOCK_ENDPOINT = "mock:messageParserProcessor";
#EndpointInject(uri = MESSAGE_PARSER_PROCESSOR_MOCK_ENDPOINT)
protected MockEndpoint messageParserProcessor;
#Override
public boolean isUseAdviceWith() {
return true;
}
#Before
public void setUpContext() throws Exception {
context.getRouteDefinitions().get(0).adviceWith(context, new AdviceWithRouteBuilder() {
#Override
public void configure() throws Exception {
interceptSendToEndpoint("bean:messageParserProcessor")
.skipSendToOriginalEndpoint()
.process(MESSAGE_PARSER_PROCESSOR_MOCK_ENDPOINT);
}
});
}
#Test
public void testParser() throws Exception {
context.start();
String expectedBody = "test";
messageParserProcessor.expectedBodiesReceived(expectedBody);
ProducerTemplate template = context.createProducerTemplate();
template.sendBody(producerTemplateUri, expectedBody);
messageParserProcessor.assertIsSatisfied();
context.stop();
}
}
When I run the test I get this error:
org.apache.camel.FailedToCreateRouteException:
Failed to create route route1 at:
>>> InterceptSendToEndpoint[bean:messageParserProcessor -> [process[ref:mock:messageParserProcessor]]] <<< in route: Route(route1)[[From[aws-sqs://xxx...
because of No bean could be found in the registry for: mock:messageParserProcessor of type: org.apache.camel.Processor
Same error if I replace interceptSendToEndpoint(...) with mockEndpointsAndSkip("bean:messageParserProcessor")
The test can be executed (but obviously doesn't pass) when I don't use a mock:
interceptSendToEndpoint("bean:messageParserProcessor")
.skipSendToOriginalEndpoint()
.process(new Processor() {
#Override
public void process(Exchange exchange) throws Exception {}
});
So the problem is the mock that is not found, what is wrong in the way I create it?
So I found a workaround to retrieve mocks from the registry:
interceptSendToEndpoint("bean:messageParserProcessor")
.skipSendToOriginalEndpoint()
.bean(getMockEndpoint(MESSAGE_PARSER_PROCESSOR_MOCK_ENDPOINT));
// Instead of
// .process(MESSAGE_PARSER_PROCESSOR_MOCK_ENDPOINT);
But I still don't understand why using .process("mock:someBean") doesn't work...
I am not sure what the problem is with my small application, if it resides on the RouteBuilder or within the ProducerTemplate
Either way, my "Test message" is not logged when running this application.
What may be going wrong here?
public static void main(String[] args) {
Main main = new Main();
main.addRouteBuilder(new RouteBuilder() {
#Override
public void configure() throws Exception {
from("seda:myqueue").log(LoggingLevel.INFO, "${in.body").end();
}
});
ProducerTemplate producerTemplate = main.getOrCreateCamelContext().createProducerTemplate();
producerTemplate.setDefaultEndpointUri("seda:myqueue");
producerTemplate.sendBody("Test message");
}
It doesn't look like you are creating and starting the context which is probably why the message never reaches your route. Here is an example to get you started:
https://examples.javacodegeeks.com/enterprise-java/apache-camel/apache-camel-hello-world-example/
import org.apache.activemq.camel.component.ActiveMQComponent;
import org.apache.camel.CamelContext;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
public class CamelHelloWorldExample {
public static void main(String[] args) throws Exception {
CamelContext context = new DefaultCamelContext();
try {
context.addComponent("activemq", ActiveMQComponent.activeMQComponent("vm://localhost?broker.persistent=false"));
context.addRoutes(new RouteBuilder() {
#Override
public void configure() throws Exception {
from("activemq:queue:test.queue")
.to("stream:out");
}
});
ProducerTemplate template = context.createProducerTemplate();
context.start();
template.sendBody("activemq:test.queue", "Hello World");
Thread.sleep(2000);
} finally {
context.stop();
}
}
}
Notice context.start() and context.stop();
I wanna to write a DataSource which is DataStream from Tarantool-java https://github.com/tarantool/tarantool-java.

I have a camel app which look something like below which has a route like below:-
from("direct:getMarketplaceOrders").to("bean:orderHelper?method=getMarketplaceOrders");
The entry point of the code look something like below:
public class OrderMainApp {
public static void main(String... args) throws Exception {
OrderMainApp orderMainApp = new OrderMainApp();
DefaultCamelContext camelContext = new DefaultCamelContext();
ProducerTemplate producer = camelContext.createProducerTemplate();
camelContext.setRegistry(orderMainApp.createRegistry(producer));
camelContext.addRoutes(new OrderRouteBuilder(producer));
camelContext.start();
}
protected JndiRegistry createRegistry(ProducerTemplate producer) throws Exception {
JndiRegistry jndi = new JndiRegistry();
OrderHelper orderHelper = new OrderHelper();
orderHelper.setProducer(producer);
jndi.bind("orderHelper", orderHelper);
return jndi;
}
}
In OrderRouteBuilder configure has routes like below:-
//processor is a custom JSONProcessor extending Processor
from("jetty:http://localhost:8888/orchestratorservice").process(processor);
from("direct:getMarketplaceOrders").to("bean:orderHelper?method=getMarketplaceOrders");
My goal is to test the response I receive from bean:orderHelper?method=getMarketplaceOrders when I place a request on direct:getMarketplaceOrders
orderHelper.getMarketplaceOrders looks like below:-
public OrderResponse getMarketplaceOrders(GetMarketplaceOrdersRequest requestParam) throws Exception
My test class look something like below:-
public class OrderMainAppTest extends CamelTestSupport {
#Produce(uri = "direct:getMarketplaceOrders")
protected ProducerTemplate template;
#EndpointInject(uri = "bean:orderHelper?method=getMarketplaceOrders")
protected MockEndpoint resultEndpoint;
#Test
public void testSendMatchingMessage() throws Exception {
String expectedBody = "<matched/>";
template.sendBody("{\"fromDateTime\": \"2016-01-11 10:12:13\"}");
resultEndpoint.expectedBodiesReceived(expectedBody);
resultEndpoint.assertIsSatisfied();
}
#Override
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
#Override
public void configure() {
from("direct:getMarketplaceOrders").to("bean:orderHelper?method=getMarketplaceOrders");
}
};
}
}
Whenever I am running the test I am getting the below exception:-
java.lang.IllegalArgumentException: Invalid type: org.apache.camel.component.mock.MockEndpoint which cannot be injected via #EndpointInject/#Produce for: Endpoint[bean://orderHelper?method=getMarketplaceOrders]
I am guessing this is because I am not able to pass on OrderHelper to the camel test context. Can some one let me know how can I inject the bean in the mock result end point?
EDIT:-
I tried modifying my test class as follows:-
public class OrderMainAppTest extends CamelTestSupport {
protected OrderHelper orderHelper = new OrderHelper();
#Produce(uri = "direct:getMarketplaceOrders")
protected ProducerTemplate template;
#EndpointInject(uri = "mock:intercepted")
MockEndpoint mockEndpoint;
#Before
public void preSetup() throws Exception {
orderHelper.setProducer(template);
};
#Test
public void testSendMatchingMessage() throws Exception {
GetMarketplaceOrdersRequest request = new GetMarketplaceOrdersRequest();
request.setFromDateTime("2016-01-11 10:12:13");
request.setApikey("secret_key");
request.setMethod("getMarketplaceOrders");
request.setLimit(10);
request.setOffset(2);
template.sendBody(request);
mockEndpoint.expectedBodiesReceived("{\"success\":\"false\"");
}
#Override
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
#Override
public void configure() {
interceptSendToEndpoint("bean:orderHelper?method=getMarketplaceOrders")
.to("mock:intercepted"); from("direct:getMarketplaceOrders").to("bean:orderHelper?method=getMarketplaceOrders");
}
};
}
#Override
protected JndiRegistry createRegistry() throws Exception {
return getRegistry();
}
protected JndiRegistry getRegistry() {
JndiRegistry jndi = new JndiRegistry();
jndi.bind("orderHelper", orderHelper);
return jndi;
}
}
The above code is making the request correctly and is flowing through my app correctly. But I am not able to intercept the response of orderHelper.getMarketplaceOrders. The above code is intercepting only the request. I tried changing to template.requestBody(request). But still no luck.
This error means you can't inject a bean: endpoint into a MockEndpoint.
If you want to "intercept" the call into your OrderHelper, you can use interceptSendToEndpoint in your route :
#EndpointInject(uri = "mock:intercepted")
MockEndpoint mockEndpoint;
...
#Override
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
#Override
public void configure() {
interceptSendToEndpoint("bean:orderHelper?method=getMarketplaceOrders")
.to("mock:intercepted");
from("direct:getMarketplaceOrders")
.to("bean:orderHelper?method=getMarketplaceOrders");
}
};
See : http://camel.apache.org/intercept.html
By updating my createRouteBuilder as shown below. I am able to intercept the response and send it to a mock endpoint where I can do the assertion.
#Override
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
#Override
public void configure() {
from("direct:getMarketplaceOrders").to("bean:orderHelper?method=getMarketplaceOrders").onCompletion()
.to("mock:intercepted");
}
};
}
