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>

Another very interesting feature that Spring provides is to manage the HTTP session. It facilitates to take decisions about the session timeout, how many concurrent sessions an authenticated user can handle, and session fixation protection. It also prevents the user from concurrently authenticating the application from more than one instance. This feature helps in preventing a user from sharing his username to access the product from multiple locations. The session management will be handled by SessionManagementFilter and SessionAuthenticationStrategy. Let's first find out how the Spring Session management is different from the traditional HTTP session management:

  • Problems handling multiple accounts: Usually, many of us have more than one account: one for personal use and another for official use. If the application tracks the user to find whether he is currently logged in or not using HttpSession, we have to log out of one account and then log in to the other account...
