forezp/SpringCloudLearning ? reverse-engineered prompt

Build me a Spring Cloud learning project in Java that shows a bunch of small runnable examples for common microservice pieces like service discovery, load balancing, service calls, circuit breaking, API gateway, config management, and tracing. I want it organized as separate example apps so I can start each chapter on its own and see how the pieces work together.

Please make it easy to run locally, with clear startup order and simple sample endpoints that show one service calling another, plus basic fallback behavior when a service is down. If it makes sense, include examples for older Spring Cloud patterns and newer ones too, since this is meant to be a tutorial style codebase. Add a simple README that explains what each example is for and how to launch it.

If you need to check current Spring Boot or Spring Cloud docs online to keep versions compatible, go ahead and do that.
