Logging Correlation Id in Spring Boot 3.2.1

In this tutorial, We will learn How to log correlationId in each log statement.

As we know spring boot starts logging a correlation Id for each log relating to Http transaction. This behavior is ON by default as long as micrometer tracing is enabled.

What is Correlation Id ?

A Correlation ID is a unique identifier assigned to a request that allows tracking it through various components.

for example: k205991b-c613–4acd-97b8–59112b2b2ak0

Why Use Correlation IDs in Spring Boot?

Challenges: Because it is difficult to trace the requests in a distributed system without Correlation IDs.

Benefits: Easier to debugging and troubleshooting with Correlation IDs.

For Example : if multiple clients calling to same API then it will print all the logs mixed .

Multiple Clients calling to same API.

Then it is difficult to identify the sequence of request processed logs. Here below we can see the logs without implementation of correlationId when multiple clients calling API.
