Overview of this book

Spring Boot is a lightweight framework that provides a set of tools to create production-grade applications and services. Spring Boot 2.0 Projects is a comprehensive project-based guide for those who are new to Spring, that will get you up to speed with building real-world projects. Complete with clear step-by-step instructions, these easy-to-follow tutorials demonstrate best practices and key insights into building efficient applications with Spring Boot. The book starts off by teaching you how to develop a web application using Spring Boot, followed by giving you an understanding of creating a Spring Boot-based simple blog management system that uses Elasticsearch as the data store. Next, you’ll build a RESTful web services application using Kotlin and the Spring WebFlux framework - a new framework that enables you to create reactive applications in a functional way. Toward the last few chapters, you will build a taxi-hailing API with reactive microservices using Spring Boot, in addition to developing a Twitter clone with the help of a Spring Boot backend. To build on your knowledge further, you’ll also learn how to construct an asynchronous email formatter. By the end of this book, you’ll have a firm foundation in Spring programming and understand how to build powerful, engaging applications in Java using the Spring Boot framework.

Generating Spring Boot Projects

In this book, we will be using http://start.spring.io, which is a convenient tool for generating Spring Projects with the required dependencies to get started. This tool supports multiple Spring Boot versions, programming languages (Java, Groovy, Kotlin), project types (Maven, Gradle), and dependencies. Learning to use this tool will help readers to get started quickly with Spring Projects. The following is a screenshot of the tool to help us get familiarized with it:

This tool allows the selection of a Project type (Maven Project, Gradle Project), programming language (Java, Groovy, Kotlin), Spring Boot version (2.0.*, 1.5.*), project artifact group, artifact name, and project dependencies. After selecting the correct options, click on Generate Project will download a ZIP file of the project.

The ZIP file needs to be extracted first before being used. The extracted ZIP file will have the following structure:

<Project Name>/
├── src/
├── pom.xml
├── mvnw
└── mvnw.bat

Opening the generated project with IntelliJ

To open the generated project with IntelliJ, we perform the following steps:

  1. Open IntelliJ IDE.
  2. Select File | Open from the menu bar as shown in the following screenshot:
  1. Navigate to the location where the extracted project is and click on OK after selecting the project, shown as follows:
  1. The IDE will show the opened project.

Opening the generated project with STS

To open the generated project the Spring Tool Suite, we perform the following steps:

  1. Open STS.
  2. Select File | Open Projects from File System... from the menu bar, as shown in the following screenshot:
  1. From the dialog box that launched, click on the Directory... button:
  1. Navigate to the extracted project location and Click on OK after selecting the project:
  1. Finally, click on Finish on the import projects dialog box.
  2. The IDE will show the opened project.
