In this course, you will learn about the Spring Boot framework and build an e-commerce web application using reactive programming. You will find that some of the newest ideas in Spring Boot are applied to some well-seasoned favorite problems that Java developers have experience with.

The course approaches these old problems with new concepts and more efficient tools. You’ll learn reactive programming, WebFlux, and the basic project structure of a Spring Boot application. Next, you’ll cover data access with MongoDB, developer tools, and testing applications with Spring Boot. Then, you’ll learn the operational features, building hypermedia APIs, reactive streams, messaging,  RSockets, and OpenID, all from the most pragmatic standpoints.

After finishing the course, you'll be able to build state of the art web applications using Spring Boot and MongoDB. You'll also learn the art of writing test cases, become proficient in building APIs, and much more.

# Tracing HTTP calls with `/actuator/httptrace`

Spring Boot Actuator provides a convenient way to see who’s making calls to our application. Along with that comes a whole host of questions.

* What types of clients are most popular? Mobile? Or a certain browser?

* Are people making requests in certain languages? Do we need internationalization?

* Which endpoints are being hit the most? From where?

This is the type of data analysis that can help us tailor our site to match
customer needs, and to switch it on in a snap!

Spring Boot provides the `HttpTraceRepository` interface. Any registered bean that implements this interface is picked up and automatically used to service
calls to `/actuator/httptrace`.

“Any registered bean” means that Spring Boot doesn’t automatically provide that type of bean. Instead, we must make the choice and create one.


To get familiar with this endpoint, we can use an out-of-the-box memory-based
version of this interface, the `InMemoryHttpTraceRepository`.
We can easily add this bean definition to the class where we defined the Spring
Boot application runner:
