Overview

This guide introduces Guice, a framework streamlining the Dependency Injection (DI) pattern in Java development. The guide includes a simple example, guiding users through project setup and essential steps. It explains Dependency Injection and how Guice simplifies this pattern.

What is Guice?

Guice streamlines Java development by replacing factories and ‘new’ with ‘@Inject’. It enhances type safety and API design, providing focused features with clear justifications. Guice prioritizes code readability, avoids surprises, and aims for fast development. Introduced in 2006, it’s proven in critical applications and offers an enjoyable experience for developers.

Running the Example

The first step is to clone the project repository and navigate into the project folder:

git clone https://github.com/wagnerjfr/guice-simple-example.git

cd guice-simple-example

After that, it’s required to build

mvn clean package

And finally, run:

java -jar…
