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.

Summary

Congratulations on completing this chapter, where the skills and knowledge required to build an asynchronous, scalable Email Formatter application were discussed.

This chapter showed you how to use Spring Data JPA for creating entities and repositories to store data in a relational database management system (RDBMS). An in-memory database named H2 was used for demonstration.

Next, we explained how to use Apache FreeMarker to format emails by replacing placeholders with actual values and generating HTML content dynamically.

Furthermore, we explained how to write producers and consumers for Apache Kafka using Spring Kafka library. Spring Kafka does a lot of the heavy lifting with auto-configuration so that it is easier to develop.

We explained how to use Spring Web MVC REST controllers to accept reset password requests from users and also how to protect endpoints using...
