How To Install atinject on CentOS 8

atinject is Dependency injection specification for Java (JSR-330)

Introduction

In this tutorial we learn how to install atinject on CentOS 8.

What is `atinject`

This package specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.

We can use yum or dnf to install atinject on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install atinject.
