Mastering Microservices with Java 9

Setting Up the Development Environment

This chapter focuses on the development environment setup and configurations. If you are familiar with the tools and libraries, you could skip this chapter and continue with Chapter 3, Domain-Driven Design, where you could explore the domain-driven design (DDD).

This chapter will cover the following topics:

  • NetBeans IDE installation and setup
  • Spring Boot configuration
  • Sample REST program with Java 9 modules
  • Building setup
  • REST API testing using the Postman extension of Chrome

This book will use only the open source tools and frameworks for examples and code. This book will also use Java 9 as its programming language, and the application framework will be based on the Spring Framework. This book makes use of Spring Boot to develop microservices.

NetBeans' Integrated Development Environment (IDE) provides state of the art support for...

NetBeans IDE installation and setup

NetBeans IDE is free and open source and has a big community of users. You can download the NetBeans IDE from its official website, https://netbeans.org/downloads/.

At the time of writing this book, NetBeans for Java 9 was available only as a nightly build (downloadable from http://bits.netbeans.org/download/trunk/nightly/latest/). As shown in the following screenshot, download all the supported NetBeans bundles as we'll use Javascript too:

NetBeans bundles

GlassFish Server and Apache Tomcat are optional. The required packs and runtimes are denoted as Already Installed (as NetBeans was already installed on my system):

NetBeans packs and runtimes

After downloading the installation, execute the installer file. Accept the license agreement as shown in the following screenshot, and follow the rest of the steps to install the NetBeans IDE...

Spring Boot configuration

Spring Boot is an obvious choice to develop state-of-the-art production-ready applications specific to Spring. Its website (https://projects.spring.io/spring-boot/) also states its real advantages:

Takes an opinionated view of building production-ready Spring applications. Spring Boot favors convention over configuration and is designed to get you up and running as quickly as possible.

Spring Boot overview

Spring Boot is an amazing Spring tool created by Pivotal and it was released in April 2014 (GA). It was developed based on the request of SPR-9888 (https://jira.spring.io/browse/SPR-9888) with the title Improved support for 'containerless' web application architectures.

You must be wondering...

Sample REST program

We will use a simple approach to building a standalone application. It packages everything into a single executable JAR file, driven by a main() method. Along the way, you use Spring's support for embedding the Jetty servlet container as the HTTP runtime, instead of deploying it to an external instance. Therefore, we would create the executable JAR file in place of the war that needs to be deployed on external web servers, which is a part of the rest module. We'll define the domain models in the lib module and API related classes in the rest module.

The following are pom.xml of the lib and rest modules.

The pom.xml file of the lib module:

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation...

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...

REST API testing using the Postman Chrome extension

This book uses the Postman - REST Client extension for Chrome to test our REST service. I use the 5.0.1 version of Postman. You can use the Postman Chrome application or any other REST Client to test your sample REST application, as shown in the following screenshot:

Postman - Rest Client Chrome extension

Let's test our first REST resource once you have the Postman - REST Client installed. We start the Postman - REST Client from either the Start menu or from a shortcut.

By default, the embedded web server starts on port 8080. Therefore, we need to use the http://localhost:8080/<resource> URL for accessing the sample REST application. For example: http://localhost:8080/calculation/sqrt/144.

Once it's started, you can type the Calculation REST URL for sqrt and value 144 as the path parameter. You can see it in...

Summary

In this chapter, you have explored various aspects of setting up a development environment, Maven configuration, Spring Boot configuration, and so on.

You have also learned how to make use of Spring Boot to develop a sample REST service application. We learned how powerful Spring Boot is—it eases development so much that you only have to worry about the actual code, and not about the boilerplate code or configurations that you write. We have also packaged our code into a JAR file with an embedded application container Jetty. It allows it to run and access the web application without worrying about the deployment.

In the next chapter, you will learn the domain-driven design (DDD) using a sample project that can be used across the rest of the chapters. We'll use the sample project online table reservation system (OTRS) to go through various phases of microservices...

Key benefits

  • Use domain-driven design to build microservices
  • Use Spring Cloud to use Service Discovery and Registeration
  • Use Kafka, Avro and Spring Streams for implementing event based microservices

Description

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.

Who is this book for?

This book is for Java developers who are familiar with the microservices architecture and now wants to take a deeper dive into effectively implementing microservices at an enterprise level. A reasonable knowledge level and understanding of core microservice elements and applications is expected.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
