Software Architecture with Spring 5.0

By: René Enríquez, Alberto Salazar

Overview of this book

Spring 5 and its ecosystem can be used to build robust architectures effectively. Software architecture is the underlying piece that helps us accomplish our business goals whilst supporting the features that a product demands. This book explains in detail how to choose the right architecture and apply best practices during your software development cycle to avoid technical debt and support every business requirement. Choosing the right architecture model to support your business requirements is one of the key decisions you need to take when a new product is being created from scratch or is being refactored to support new business demands. This book gives you insights into the most common architectural models and guides you when and where they can be used. During this journey, you’ll see cutting-edge technologies surrounding the Spring products, and understand how to use agile techniques such as DevOps and continuous delivery to take your software to production effectively. By the end of this book, you’ll not only know the ins and outs of Spring, but also be able to make critical design decisions that surpass your clients’ expectations.

  • Transforming the file tuples with a business class 
  • Storing the results in a database

The following diagram illustrates our implementation:

First, we are going to create a new, clean project, using the Spring initializer (, as we did in the previous section:


Remember to add the Batch reference to our project, like we did in the previous example.

Don't forget to add a database driver as a dependency in the pom.xml file. For testing purposes, we are going to use HSQL (, as follows:
