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

Chapter 3. Implementing MVC Design Patterns

A rigorous set of recipes on how to kick off Spring 5.0 projects verified that the core platform is still composed of almost the same APIs found in its previous version. Even though Spring 5.0 promotes the new functional and reactive web framework, it still upholds the traditional annotations and web APIs such as @Controller, @RequestMapping, @Bean, the ApplicationContext interface, and many other old features such JSR-330 annotations.

Now, we focus on how the basic MVC components are written if Spring 5.0 is used. We will observe the differences and similarities between Spring 5.0 and the other versions especially when creating data sources, the Data Access Object (DAO) layer, service layers, validation, and other types of request handling.

In this chapter, you will learn the following:

  • Creating a simple @Controller
  • Creating a simple @Controller with method-level URL mapping
  • Designing a simple form @Controller
  • Creating a multi-action @Controller
  • Form...
