How to pass request-id in quarkus through activeMQ? - activemq

Question

My application is generating a request and then sending that request to a listener(activemq here) for further processing, I am trying to add a request-id to the logs for better tracing of errors but the request-id is not passing to the listener it works fine before that, i have tried the approach mentioned in this answer https://stackoverflow.com/a/70892802/19343662
These are the files i have created...
RequestIdFilter:
package com.cashfree.common.dexterreport.filters;
import io.vertx.core.http.HttpServerRequest;
import java.util.UUID;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.core.Context;
import javax.ws.rs.ext.Provider;
import org.slf4j.MDC;
#Provider
public class RequestIdFilter implements ContainerRequestFilter, ContainerResponseFilter {
#Context
HttpServerRequest request;
private static final String REQUEST_ID_HEADER_NAME = "X-Request-Id";
private static final String REQUEST_ID = "requestId";
#Override
public void filter(ContainerRequestContext context) {
MDC.put(REQUEST_ID, getRequestIdFromHeader(request));
}
#Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) {
MDC.remove(REQUEST_ID);
}
private String getRequestIdFromHeader(final HttpServerRequest request) {
String requestId = request.getHeader(REQUEST_ID_HEADER_NAME);
if (requestId == null || requestId.length() == 0) {
requestId = generateUniqueRequestId();
}
return requestId;
}
private String generateUniqueRequestId() {
return UUID.randomUUID().toString();
}
}
MdcContextProvider
import java.util.Map;
import org.eclipse.microprofile.context.spi.ThreadContextProvider;
import org.eclipse.microprofile.context.spi.ThreadContextSnapshot;
import org.slf4j.MDC;
public class MdcContextProvider implements ThreadContextProvider {
#Override
public ThreadContextSnapshot currentContext(Map<String, String> props) {
Map<String, String> propagate = MDC.getCopyOfContextMap();
return () -> {
Map<String, String> old = MDC.getCopyOfContextMap();
MDC.setContextMap(propagate);
return () -> {
MDC.setContextMap(old);
};
};
}
#Override
public ThreadContextSnapshot clearedContext(Map<String, String> props) {
return () -> {
Map<String, String> old = MDC.getCopyOfContextMap();
MDC.clear();
return () -> {
MDC.setContextMap(old);
};
};
}
#Override
public String getThreadContextType() {
return "SLF4J MDC";
}
}
A ThreadContextProvider file created at src/main/resources/META-INF/services/org.eclipse.microprofile.context.spi.ThreadContextProvider having line specifying the ref path of mdcContextProvider : com.org.common.report.Provider.MdcContextProvider
But this is not working although i was expecting this, since the the thread started by listener and the thread which passes the message to it has no connection between them, is there any way where i can pass the request-id to the listener...

Answer 1

I was able to do it with a workaround.
Because each Listener runs/spawn up its own thread. you cannot expect the request ID to be available in MDC property as MDC property is thread local.
I was able to achieve it by passing the value as part of ActiveMQ's message
Example:
Wrap every message you exchange in a Generic class
class ActiveMqMsg {
private Message message;
private Map<String, Object> properties;
}
and expect Listener to deserialize it to ActiveMqMsg and read the properties and set it to MDC property again.
Hope this helps.
