DependencyInjector

A lightweight and easy-to-use dependency injection framework in Java, featuring constructor-based injection and automatic post-construction method invocation with @Inject and @PostConstruct annotations.

Example Usage:

import ovh.neziw.injector.Injector;

public final class MyApplication {

    public static void main(final String[] args) {
        final Injector injector = new Injector();
        injector.bind(FirstService.class, new FirstService());
        injector.bind(SecondService.class, new SecondService());

        final MyClass myClass = injector.createInstance(MyClass.class);
        myClass.sendMessages();
    }
}

import ovh.neziw.injector.Inject;
import ovh.neziw.injector.PostConstruct;

public class MyClass {

    private final FirstService firstService;
    private final SecondService secondService;

    @Inject
    public MyClass(final FirstService firstService, final SecondService secondService) {
        this.firstService = firstService;
        this.secondService = secondService;
    }

    @PostConstruct
    void init() {
        System.out.println("Example PostConstruct method called");
    }

    public void sendMessages() {
        this.firstService.doSomething();
        System.out.println(this.secondService.getSecondServiceMessage());
    }
}

public class FirstService {

    public void doSomething() {
        System.out.println("Sending something from FirstService");
    }
}

public class SecondService {

    public String getSecondServiceMessage() {
        return "This is the second service message!";
    }
}

Output:

> Example PostConstruct method called
> Sending something from FirstService
> This is the second service message!
