Building a Basic Web Application

This chapter will help readers get started developing web applications using Spring Boot 2.0. It will enable experts as well as beginners with Spring Boot web application development to understand the concepts behind a web application. It will explain these concepts by walking the reader through the process of developing a web application that enables the submitting of comments to a scrum retrospective meeting. This web application will use an embedded database for persistence, Spring Data JPA for a model, Spring Thymeleaf for a view, and Spring Web MVC for controllers.

The following topics will be covered in this chapter:

Using Spring Data JPA for persistence
Using Thymeleaf for view
Using Spring Web MVC with servlet 3.x for controller
Using Spring Security for authentication and authorization
Demonstrating Retro Board

Description

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.
