Spring 5.0 Projects

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.

Our Blogpress application has a login functionality to access certain pages and functionalities that are not accessible by a normal (anonymous) user. It requires a good amount of effort to incorporate it if we build authentication and authorization on our own from scratch. Spring provides a feature called Spring Security, which does exactly what we need here.

Spring Security is an open source, highly comprehensive, powerful, and customizable framework used to implement authentication and authorization in J2EE-based web applications. It is a sub-project (module) of the Spring Framework.

Before talking further, it is important to understand the difference between authentication and authorization.

Authentication is the process of validating or determining someone or something in what it claims to be. There are several mechanisms to perform authentication. The most straightforward way of performing authentication is to provide a username and password...
