Spring 5.0 Cookbook

Overview of this book

The Spring framework has been the go-to framework for Java developers for quite some time. It enhances modularity, provides more readable code, and enables the developer to focus on developing the application while the underlying framework takes care of transaction APIs, remote APIs, JMX APIs, and JMS APIs. The upcoming version of the Spring Framework has a lot to offer, above and beyond the platform upgrade to Java 9, and this book will show you all you need to know to overcome common to advanced problems you might face. Each recipe will showcase some old and new issues and solutions, right from configuring Spring 5.0 container to testing its components. Most importantly, the book will highlight concurrent processes, asynchronous MVC and reactive programming using Reactor Core APIs. Aside from the core components, this book will also include integration of third-party technologies that are mostly needed in building enterprise applications. By the end of the book, the reader will not only be well versed with the essential concepts of Spring, but will also have mastered its latest features in a solution-oriented manner.

Preface

Implementing authentication filters, login success, and failure handlers


The previous recipe taught us how to create a custom authentication manager and a chain of providers that can help control the different gateways of authentication and authorization processes. Now, we will expand on customization, covering the setup of a filter stack and its handlers.

Getting started

This recipe will create a security model out of Spring Security 4.2.2, where there is a filter chain of security transactions which includes all the managers and providers of the previous recipe, with the addition of security objects called handlers. This recipe is the most important part of this chapter when it comes to stretching the flexibility of the security architecture of the Spring Security framework.

How to do it...

Let us now add important supporting components to the authentication process established by the previous recipe:

  1. Create and apply two filters needed to establish a security filter chain in this new security...
