I managed to create a custom MessageVerifier for JMS and ActiveMQ which looks like this:
package de.itemis.seatreservationservice;
import com.fasterxml.jackson.databind.ObjectMapper;
import de.itemis.seatreservationservice.domain.ReservationRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.contract.verifier.messaging.MessageVerifier;
import org.springframework.context.annotation.Primary;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.messaging.support.GenericMessage;
import org.springframework.stereotype.Component;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.TextMessage;
import java.io.IOException;
import java.util.Map;
import java.util.concurrent.TimeUnit;
@Component
@Primary
public class JmsMessageVerifier implements MessageVerifier {
@Autowired
JmsTemplate jmsTemplate;
@Autowired
ObjectMapper mapper;
@Override
public void send(Object message, String destination) {
jmsTemplate.convertAndSend(destination, message, new ReplyToProcessor());
}
@Override
public Object receive(String destination, long timeout, TimeUnit timeUnit) {
jmsTemplate.setReceiveTimeout(timeout);
return receiveMessage(destination);
}
@Override
public Object receive(String destination) {
return receiveMessage(destination);
}
@Override
public void send(Object payload, Map headers, String destination) {
ReservationRequest request = null;
try {
request = mapper.readValue((String) payload, ReservationRequest.class);
} catch (IOException e) {
e.printStackTrace();
}
jmsTemplate.convertAndSend(destination, request, new ReplyToProcessor());
}
private Object receiveMessage(String queueName) {
Message message = jmsTemplate.receive(queueName);
TextMessage textMessage = (TextMessage) message;
try {
return new GenericMessage<>(textMessage.getText());
} catch (JMSException e) {
e.printStackTrace();
return null;
}
}
}
Currently i need them in both test folders (producer and consumer).
Normally i would expect that the JmsMessageVerifier in my Producer would be packaged inside the generated stubs JAR so that the consumer contract tests use this JmsMessageVerifier instead of implementing their own.
What are your thoughts in this Marcin Grzejszczak ?
I would create an Issue for that if its a useful feature.
Here is the repository with both services:
