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 asynchronous controllers


For enhanced performance and faster request handling, asynchronous controllers have been present in any Spring instalments, to be used in cases where the service execution takes a practically large amount of time or the DAO layer retrieves an unpredictable, uncertain, erratic, and intermittent transmission of data from a certain data repository. Although rare, complex, and complicated to manage, asynchronous controllers can indeed help cut the time spent for bulk transactions compared to normal controller processing. With the use of callbacks, these types of controllers can manage unsuccessful data retrieval, which is one way of handling exceptions. Overall, given high-powered hardware resources and software applications servers, asynchronous @Controller transactions can help alleviate the unwanted acquisition of high-powered hardware specification.
