# 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:

```java

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();

    }

}

```

```java

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());

    }

}

```

```java

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!

```

### Adding dependency

**Maven:**

```xml

    

        neziw-repo

        https://repo.neziw.ovh/releases

    

    

        ovh.neziw

        DependencyInjector

        1.0.0

    

```

**Gradle:**

```groovy

repositories {

    maven {

        name "neziw-repo"

        url "https://repo.neziw.ovh/releases"

    }

}

implementation "ovh.neziw:DependencyInjector:1.0.0"

```
