1.3. Introducing the case study

This section introduces a real application that we use throughout this book to illustrate the use of Spring Batch: an online store application. This use case starts out small and simple but remains realistic in terms of technical requirements. It not only demonstrates Spring Batch features but also illustrates how this use case fits into the enterprise landscape.

By implementing this use case using Spring Batch, you gain a practical understanding of the framework: how it implements efficient reading and writing of large volumes of data, when to use built-in components, when to implement your own components, how to configure a batch job with the Spring lightweight container, and much more. By the end of this chapter, you’ll have a good overview of how Spring Batch works, and you’ll know exactly where to go in this book to find what you need for your batch applications.
