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.

Setting up the application build

Whatever the pom.xml files, whatever we have used until now is enough to execute our sample REST service. This service would package the code into a JAR file. To make this JAR executable we need to opt for the following options:

  • Running the Maven tool
  • Executing with the Java command

The following sections will cover them in detail.

Running the Maven tool

This method may not work because Java 9, Spring Boot 2, and Spring Framework 5 are all in either in early or snapshot release. In case it does not work, please use a project using Java commands.

Here, we use the Maven tool to execute the generated JAR file, the steps for this are as follows:

  1. Right-click on the pom.xml file.
  2. Select Run Maven...
