Modules

.

File	Summary
mvnw	Enables Maven wrapper setup for project bootstrap and dependency retrieval. Dynamically downloads the maven-wrapper.jar if missing, establishing a consistent project setup and reducing manual dependency management overhead.
mvnw.cmd	Facilitates Maven setup by validating and initializing project directories, handling Java environments, and dynamically downloading dependencies when missing. It ensures a smooth project start-up and configuration.

src.test.java.in.rahulojha.micrometertracingdemo

File	Summary
MicrometerTracingDemoApplicationTests.java	Verifies Spring Boot application context loading by running tests with SpringBootTest annotation.

src.main.java.in.rahulojha.micrometertracingdemo

File	Summary
MicrometerTracingDemoApplication.java	Ensures microservice readiness** by bootstrapping the application and enabling scheduling. Part of the micrometer-tracing-demo repository architecture, this file facilitates Spring Boot's functionality for enhanced performance monitoring and tracing capabilities.

src.main.java.in.rahulojha.micrometertracingdemo.aop

File	Summary
ScheduledSpanAspect.java	Enables wrapping scheduled tasks in spans for tracing with Micrometer, enhancing observability in the micrometer-tracing-demo repository. AOP aspect intercepts scheduled methods, creating spans with method names for monitoring.

src.main.java.in.rahulojha.micrometertracingdemo.scheduler

File	Summary
DemoScheduler.java	Implements a scheduled task with logging functionality in the Micrometer Tracing Demo repository. Executes a task every 30 seconds, displaying iterative progress messages with thread sleeps for demonstration.

src.main.java.in.rahulojha.micrometertracingdemo.controller

File	Summary
DemoController.java	Demonstrate logging and endpoint for performance testing in the micrometer-tracing-demo. The code in DemoController.java handles requests to /test route, logging each iteration and inducing a waiting period for performance evaluation.
