Overview of this book

Spring makes it easy to create RESTful applications, merge with social services, communicate with modern databases, secure your system, and make your code modular and easy to test. With the arrival of Spring Boot, developers can really focus on the code and deliver great value, with minimal contour. This book will show you how to build various projects in Spring 5.0, using its features and third party tools. We'll start by creating a web application using Spring MVC, Spring Data, the World Bank API for some statistics on different countries, and MySQL database. Moving ahead, you'll build a RESTful web services application using Spring WebFlux framework. You'll be then taken through creating a Spring Boot-based simple blog management system, which uses Elasticsearch as the data store. Then, you'll use Spring Security with the LDAP libraries for authenticating users and create a central authentication and authorization server using OAuth 2 protocol. Further, you'll understand how to create Spring Boot-based monolithic application using JHipster. Toward the end, we'll create an online book store with microservice architecture using Spring Cloud and Net?ix OSS components, and a task management system using Spring and Kotlin. By the end of the book, you'll be able to create coherent and ?exible real-time web applications using Spring Framework.

Blogpress - A Simple Blog Management System

Spring supports the development of enterprise-grade applications on the Java platform. There are numerous such application that come under its purview, popular among which are Spring Model-View-Controller (MVC), Spring Security, Spring Data, Spring Batch, and Spring Cloud.

In the previous two chapters, we started exploring Spring MVC framework along with other building blocks, like Spring Data and RestTemplate, along with JavaScript frameworks like Angular, Bootstrap, and jQuery to build the web-based application. We have also seen how to build a reactive web application with the help of WebFlux, a framework for creating reactive web applications.

Creating an enterprise-ready Spring-based application requires heavy configuration, which makes the process of development quite tedious and cumbersome. On top of this, setting up the...
