Overview of this book

Angular makes building applications with the web easy and Spring Boot helps get an application up and running using just a few lines of code and minimal configuration. This book provides insights into building full-stack apps using Angular and Spring Boot effectively to reduce overall development time and increase efficiency. You'll start by setting up your CI/CD pipeline and then build your web application’s backend guided by best practices. You'll then see how Spring Boot allows you to build applications faster and more efficiently by letting the Spring Framework and Spring Boot extension do the heavy lifting. The book demonstrates how to use Spring Data JPA and add its dependencies along with Postgres dependencies in the project to save or persist a user's data in a database for future use. As you advance, you'll see how to write tests and test a service using Mockito. Finally, you'll create a CI workflow or pipeline for a Spring Boot and Angular application to enable operations to deliver quality applications faster. By the end of this Spring Boot and Angular book, you'll be able to build a full-stack web application and deploy it through continuous integration and continuous deployment.

Dependency injection

We have successfully generated our own Spring Boot project, and now, we will start learning the concepts of Spring, and one of the most important concepts we need to understand is dependency injection. As we develop our backend using Spring Boot, we will mainly use dependency injection throughout our development, as this makes our Java program modular and enables easier switching of implementations.

Dependency injection is an essential feature of object-oriented programming languages, but first, let’s discuss the concept of inversion of control, which is what dependency injection is trying to achieve.

Inversion of control

Inversion of Control (IoC) is the design pattern used for object-oriented programming languages. IoC is the concept of inverting the flow of your program, and it is used for decoupling the components in your application, making your piece of code reusable and modular. Hence, the IoC design pattern will provide us with a way to...
