How can I effectively debug microservices in Java?

How can I effectively debug microservices in Java?

Debugging microservices in Java can be challenging due to their distributed nature. You can start by using logging frameworks like SLF4J or Log4j to capture logs from each service. Additionally, consider using tools like Spring Boot Actuator for health checks and metrics.

What tools can help with monitoring and logging?

For monitoring, you can use tools like Prometheus and Grafana. For logging, ELK Stack (Elasticsearch, Logstash, Kibana) is popular, as well as Splunk for centralized logging.

How do I handle exceptions across microservices?

You can implement a centralized exception handling mechanism using a global exception handler in your API gateway. This way, you can catch exceptions from all microservices and return a consistent error response.

Are there best practices for testing microservices?

Yes, some best practices include writing unit tests for individual services, integration tests for service interactions, and end-to-end tests for the entire system. Tools like JUnit and Mockito can be very helpful.
