Mastering Spring Boot 2.0

By: Dinesh Rajput

Overview of this book

Spring is one of the best frameworks on the market for developing web, enterprise, and cloud ready software. Spring Boot simplifies the building of complex software dramatically by reducing the amount of boilerplate code, and by providing production-ready features and a simple deployment model. This book will address the challenges related to power that come with Spring Boot's great configurability and flexibility. You will understand how Spring Boot configuration works under the hood, how to overwrite default configurations, and how to use advanced techniques to prepare Spring Boot applications to work in production. This book will also introduce readers to a relatively new topic in the Spring ecosystem – cloud native patterns, reactive programming, and applications. Get up to speed with microservices with Spring Boot and Spring Cloud. Each chapter aims to solve a specific problem or teach you a useful skillset. By the end of this book, you will be proficient in building and deploying your Spring Boot application.

Using the Initializr with the Spring Boot CLI


You can also use Spring Initializr from the Spring Boot CLI. It offers some commands that can be used to kick-start development. The Spring Boot CLI provides an init command to create a Spring Boot application structure and acts as a client interface to the Spring Initializr. Let's see how to use the init command to create a Spring Boot project as follows:

$ spring init

Let's see the following output of the init command:

As you can see in the preceding screenshot, a demo.zip file is created and saved to the workspace. If you unzip this project, you'll find a typical project structure with a Maven pom.xml build specification. Download the project with very minimal configuration with the Maven specification, and test it.

But actually, if you want to create a web application using Spring MVC that uses JPA for data persistence, let's see the following command that includes all the required dependencies for your application:

$ spring init -dweb, jpa
