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.

Creating Singleton and Prototype beans


Creating beans to the containers is not enough for any project specification using the Spring framework. It is always necessary to determine the lifespan of the beans through bean scopes. The following recipe will determine how to optimize a container by creating Singleton and Prototypes beans.

Getting started

The scope of the beans characterizes how many of their instances will be used by the application. It categorizes also the purpose of each bean as to why it is loaded to the Spring container. There are four scopes that can be associated with Spring beans but only two of them will be discussed in this chapter as part of the core platform.

How to do it...

This recipe will be using both ch02-xml and the ch02-jc project in declaring which beans are considered Singleton and Prototype. We will explore and identify the effects of applying either of the two scopes to the container:

  1. Open the project ch02-xml and locate the XML definition file in the ch02-xml...
