Logs are one of the most powerful tools in a developer's arsenal, providing invaluable insights into application behavior and helping debug issues effectively. However, as systems scale, logs can become overwhelming, making it challenging to track the flow of a specific request. One practical method to enhance traceability in logs is by adding a UUID (Universally Unique Identifier). This ensures that every request or operation has a unique identifier, allowing developers to filter logs for a specific execution path. This article explores how to implement this technique in Spring Boot, with detailed code examples and an analysis of related aspects.
