Overview of this book

With growing demands, organizations are looking for systems that are robust and scalable. Therefore, the Spring Framework has become the most popular framework for Java development. It not only simplifies software development but also improves developer productivity. This book covers effective ways to develop robust applications in Java using Spring. The book has three parts, where each one covers the building of a comprehensive project in Java and Spring. In the first part, you will construct a CMS Portal using Spring's support for building REST APIs. You will also learn to integrate these APIs with AngularJS and later develop this application in a reactive fashion using Project Reactor, Spring WebFlux, and Spring Data. In the second part, you’ll understand how to build a messaging application, which will consume the Twitter API and perform filtering and transformations. Here, you will also learn about server-sent events and explore Spring’s support for Kotlin, which makes application development quick and efficient. In the last part, you will build a real microservice application using the most important techniques and patterns such as service discovery, circuit breakers, security, data streams, monitoring, and a lot more from this architectural style. By the end of the book, you will be confident about using Spring to build your applications.

Spring Boot Admin


The Spring Boot Admin project is a tool that helps developers in production environments. The tool shows Spring Boot application metrics in an organized dashboard, and it makes it extremely easy to see application metrics and much more information.

The tool uses the data from the Spring Boot Actuator as an information source. The project is open source and has a lot of contributors and is an active project in the community as well.

Running Spring Boot Admin

It is a piece of cake to set up the application. We will need a new Spring Boot application, and to connect this new application with our service discovery implementation. Let's do it right now.

We can find the code on GitHub at https://github.com/PacktPublishing/Spring-5.0-By-Example/tree/master/Chapter08/admin. If you want to create a new application, go ahead; the process is similar to what we did in the previous chapters.

The project is a Spring Boot regular application, with two new dependencies:
