Mastering Microservices with Java 9 - Second Edition

Overview of this book

Microservices are the next big thing in designing scalable, easy-to-maintain applications. They not only make app development easier, but also offer great flexibility to utilize various resources optimally. If you want to build an enterprise-ready implementation of the microservices architecture, then this is the book for you! Starting off by understanding the core concepts and framework, you will then focus on the high-level design of large software projects. You will gradually move on to setting up the development environment and configuring it before implementing continuous integration to deploy your microservice architecture. Using Spring security, you will secure microservices and test them effectively using REST Java clients and other tools like RxJava 2.0. We'll show you the best patterns, practices and common principles of microservice design and you'll learn to troubleshoot and debug the issues faced during development. We'll show you how to design and implement reactive microservices. Finally, we’ll show you how to migrate a monolithic application to microservices based application. By the end of the book, you will know how to build smaller, lighter, and faster services that can be implemented easily in a production environment.

Consuming Services Using a Microservice Web Application

Now, after developing the microservices, it would be interesting to see how the services offered by the online table reservation system (OTRS) could be consumed by web or mobile applications. We will develop the web application (UI) using AngularJS/Bootstrap to build the prototype of the web application. This sample application will display the data and flow of this sample project—a small utility project. This web application will also be a sample project and will run independently. Earlier, web applications were being developed in single web archives (files with .war extensions) that contained both UI and server-side code. The reason for doing so was pretty simple, as UI was also developed using Java with JSPs, servlets, JSF, and so on. Nowadays, UIs are being developed independently using JavaScript. Therefore, these...
