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.

Storing data with Elasticsearch


Elasticsearch is a highlyscalable and full-text search open source RESTful searching, indexing, and analytics engine developed on top of Lucene. It is one of the most popular search engines for building enterprise applications today. It can save, search, and analyze data in big volumes very quickly. Mainly, it is used for applications where complex searching is required.

It is developed in Java and provides near real-time results. It is designed to work in a distributed environment to provide high availability and scalability. It is document-oriented, stores complex entity structures in JSON format, and provides a web interface to interact with.

Elasticsearch is mainly used in applications when searching for a large amount of matching products (for example, e-Commerce), using auto-complete features for partially typed input, or analyzing the huge quantities of raw data stored in a distributed fashion.
