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.

# Enabling other endpoints

Until now, we’ve only seen the default actuator endpoints,` health` and `info`, exposed to the web. Spring Boot actually has many other endpoints, but they’re disabled from web access by default.


**Actuator endpoints** offered by **Java Management Extensions (JMX)** are enabled by default, while their web-based counterparts are disabled by default. This is primarily for security reasons. JMX, in its default configuration, requires us to run **JConsole** on the same machine.
Web access to actuator endpoints is the complete opposite. While convenient, it becomes super easy to expose all our application has to offer. This is why Spring Boot 2.3 disables web access to actuator endpoints. The only exception is a shallow `health` check (only reporting `UP`) and `info` data (information we must choose to include).


So, we could include everything if we really wanted to. All it takes is a single line in `application.properties`:
