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

Creating the simple @Controller


Let us start with a recipe that will provide us with different strategies for how to implement Spring 5.0 @Controller classes. These are just typical non-reactive and non-functional features of Spring 5.0, which can be useful in the later chapters.

Getting started

Using the recipes in Chapter 1, Getting Started with Spring and Chapter 2, Learning Dependency Injection (DI), create and set up another Maven project for Spring web development and name it ch03. The project will be using the JavaConfig specification in generating the ApplicationContext. Also, this web.xml-less project will demonstrate how to optimize @Controller classes based on the number of request handlers needed and the nature of the request and response transactions.

How to do it...

In order to create our first controllers, do the following steps:

  1. Locate pom.xml inside the ch03 folder and configure it to include the entire Spring 5.0 core, Spring Web MVC module, servlet and JSP APIs, JTSL, and standard...
