Mikron is a minimalistic web-free IoC container for dependency injection and externalized configuration management for Java. To use the Maven-based project, you can add the following dependency:

<dependency>
  <groupId>net.reevik</groupId>
  <artifactId>mikron</artifactId>
  <version>${latest}</version>
</dependency>

Usage

You will use Mikron annotations to initialize the Mikron context in your Java application. In the following example, we declare a "Mikron Application" by using @ManagedApplication annotation, and instantiate the Mikron context. MikronContext is the implementation of IoC container, where managed instances reside:

@ManagedApplication(packages = {"your.package.to.scan"})
public class Main {

  public static void main(String[] args) {
    Optional<AnnotatedManagedClass> instance;
    try (MikronContext context = MikronContext.init(Main.class)) {
      instance = context.getInstance(AnnotatedManagedClass.class.getName());
    } catch (Exception e) {
      throw new RuntimeException(e);
    }
  }
}

Mikron context is the container where the managed instances reside and the dependencies between managed objects get wired. You will use @Managed annotation to declare managed instances:

@Managed
public class ManagedObject {

  @Configurable(name = "config.temp")
  private Integer temperature;

  @Wire
  private ManagedDependency managedDependency;
}

and the @Wire annotation introduces dependency injection point whereas @Configurable annotation is used to inject externalized configurations.
