How would you implement a fallback mechanism for external service calls, to handle failures gracefully in a Spring Boot application?
- Using Circuit Breaker patterns such as Hystrix.
- Using Spring Cloud Config to manage external service URLs.
- Manually retrying the service call with an exponential backoff strategy.
- Ignoring the failure and proceeding with the next operation.
Implementing a fallback mechanism for external service calls in a Spring Boot application is typically done using Circuit Breaker patterns like Hystrix. Circuit breakers detect when a service is failing, and they can redirect traffic to a fallback mechanism to handle the failure gracefully, preventing cascading failures and improving system resilience. The other options are not recommended approaches for handling failures in a production-grade Spring Boot application.
