Overview of this book

<p>Spring is the most widely used framework for Java programming and with its latest update to 5.0, the framework is undergoing massive changes. Built to work with both Java 8 and Java 9, Spring 5.0 promises to simplify the way developers write code, while still being able to create robust, enterprise applications.</p> <p>If you want to learn how to get around the Spring framework and use it to build your own amazing applications, then this book is for you.</p> <p>Beginning with an introduction to Spring and setting up the environment, the book will teach you in detail about the Bean life cycle and help you discover the power of wiring for dependency injection. Gradually, you will learn the core elements of Aspect-Oriented Programming and how to work with Spring MVC and then understand how to link to the database and persist data configuring ORM, using Hibernate.</p> <p>You will then learn how to secure and test your applications using the Spring-test and Spring-Security modules. At the end, you will enhance your development skills by getting to grips with the integration of RESTful APIs, building microservices, and doing reactive programming using Spring, as well as messaging with WebSocket and STOMP.</p>

However, today, the look and feel, the requirements, the use, the data formats, the expectations of the user and, more importantly, the mechanism have changed a lot. Internet is handling a tremendous load of data, and it's obviously hampering their performance. The request and response, as we all know, is synchronous. The user needs to wait for the response. It addresses a major problematic area--blocking of streams--that keeps the users waiting, and they never know how long they have to keep waiting. The solution to this problem is a quick response without blocking. We...
