Provides Autowiring for The Symfony2 Dependency injection Container

Symfony autowiring bundle

A simple library that provides autowiring for the Symfony2 Dependency Injection (DI) container.

This bundle supports constructor autowiring only, see http://springindepth.com/book/in-depth-ioc-autowiring.html for description.

Installation

  1. Install via composer:
composer require kutny/autowiring-bundle
  1. Add KutnyAutowiringBundle to your application kernel
// app/AppKernel.php
public function registerBundles()
{
    return array(
        // ...
        new Kutny\AutowiringBundle\KutnyAutowiringBundle(),
        // ...
    );
}

Configuration

In most cases this bundle does not require any configuration. However if your app fails to start after installing this bundle giving you Kutny\AutowiringBundle\Compiler\CannotResolveParameterException, you may need to remove some services from autowiring. See example bellow:

Example 1:

You are receiving Kutny\AutowiringBundle\Compiler\CannotResolveParameterException with message like "Class Thrace\FormBundle\Form\Type\Select2Type (service thrace_form.form.type.select2), parameter $widget".

The problem is that Thrace\FormBundle\Form\Type\Select2Type service definition does not contain explicit $widget argument definition. It is very likely that the Thrace\FormBundle developer just forgot to define the $widget argument. KutnyAutowiringBundle expects all services to have all arguments defined (or have default values). As a result we have to disable autowiring for the thrace_form.form.type.select2 service by adding it (as a regular expression) among ignored_services:


kutny_autowiring:
    ignored_services: ['thrace_form\.form\.type\.select2']

If you run into problems with more services from the Thrace\FormBundle bundle (thrace_form.form.type.select2, thrace_form.form.type.recaptcha, ...), you can easily add the whole "service namespace" to ignored_services using the following reqular expression:


kutny_autowiring:
    ignored_services: ['thrace_form\.form\.type.*']

Example 1: Simple controller autowiring

Sample controller with service autowiring (controller itself is also defined as service):

namespace Acme\DemoBundle\Controller;

use Acme\DemoBundle\Facade\ProductsFacade;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

/**
 * @Route(service="controller.products_controller")
 */
class ProductsController
{

  private $productsFacade;

    public function __construct(ProductsFacade $productsFacade)
    {
        $this->productsFacade = $productsFacade;
    }

    /**
     * @Route("/", name="route.products")
     * @Template()
     */
    public function productsAction()
    {
        return array(
            'products' => $this->productsFacade->getProducts()
        );
    }

}

Services configuration in app/config.yml:


services:
    controller.products_controller:
        class: Acme\DemoBundle\Controller\ProductsController

    facade.products_facade:
        class: Acme\DemoBundle\Facade\ProductsFacade

Example 2: Partial manual wiring

In the following example, I've added:

  • $productsPerPageLimit config option to ProductsController (must be wired manually)
  • ProductsRepository manually wired with Doctrine2 EntityManager
<?php

namespace Acme\DemoBundle\Controller;

use Acme\DemoBundle\Facade\ProductsFacade;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

/**
 * @Route(service="controller.products_controller")
 */
class ProductsController
{

    private $productsPerPageLimit;
    private $productsFacade;

    public function __construct($productsPerPageLimit, ProductsFacade $productsFacade)
    {
        $this->productsPerPageLimit = $productsPerPageLimit;
        $this->productsFacade = $productsFacade;
    }

    /**
     * @Route("/", name="route.products")
     * @Template()
     */
    public function productsAction()
    {
        return array(
            'products' => $this->productsFacade->getProducts($this->productsPerPageLimit)
        );
    }

}
<?php

namespace Acme\DemoBundle\Facade;

use Acme\DemoBundle\Repository\ProductsRepository;

class ProductsFacade
{
    private $productsRepository;

    public function __construct(ProductsRepository $productsRepository) {
        $this->productsRepository = $productsRepository;
    }

    public function getProducts($productsPerPageLimit) {
        return $this->productsRepository->getProducts($productsPerPageLimit);
    }

}
<?php

namespace Acme\DemoBundle\Repository;

use Doctrine\ORM\EntityManager;

class ProductsRepository
{
    private $entityManager;

    public function __construct(EntityManager $entityManager) {
        $this->entityManager = $entityManager;
    }

    public function getProducts($productsPerPageLimit) {
        $query = $this->entityManager->createQueryBuilder()
            ->select('p')
            ->from('AcmeDemoBundle:Product', 'p')
            ->setMaxResults($productsPerPageLimit)
            ->getQuery();

        return $query->getResult();
    }

}

Services config:


services:
    controller.products_controller:
        class: Acme\DemoBundle\Controller\ProductsController
        arguments: [10]

    facade.products_facade:
        class: Acme\DemoBundle\Facade\ProductsFacade

    repository.products_repository:
        class: Acme\DemoBundle\Repository\ProductsRepository
        arguments: [@doctrine.orm.default_entity_manager]

Autowiring bundle will autowire some services by their type for the Symfony DI Container to work with the following configuration:


services:
    controller.products_controller:
        class: Acme\DemoBundle\Controller\ProductsController
        arguments: [10, @facade.products_facade]

    facade.products_facade:
        class: Acme\DemoBundle\Facade\ProductsFacade
        arguments: [@repository.products_repository]

    repository.products_repository:
        class: Acme\DemoBundle\Repository\ProductsRepository
        arguments: [@doctrine.orm.default_entity_manager]

Provides Autowiring for The Symfony2 Dependency injection Container

Getting Started with ASP.NET Core Dependency Injection

I’ve lately been feeling my way around getting an actual, production-ready ASP.NET Core app developed, and one of the features I’ve really been digging (one of many) is native support for Dependency Injection (DI). DI is huge in modern web apps, so making it the default for ASP.NET

ActiveInject. Fast and Lightweight Dependency Injection Library

What is ActiveInject?

ActiveInject is a lightning-fast and powerful dependency injection library. It has a lot of tools and features to offer: support for nested scopes, singletons and transient bindings, modules, multi-threaded, and single-threaded injectors.

At the same time, it’s thoroughly optimized with all the dependencies graph preprocessing performed at startup time. According to the benchmarks, in some scenarios, ActiveInject is 5.5 times faster than Guice and hundreds of times faster than Spring DI. You can check the benchmark sources here.

ActiveInject_ is an independent technology of ActiveJ platform. It has no third-party dependencies on its own and can be used as a stand-alone DI library._

Getting Started

Let’s try the library out and bake some virtual cookies using ActiveInject. A cookie requires the following ingredients: FlourSugar and Butter. These ingredients form a Pastry which can be baked into a Cookie. Assume each of these entities has a POJO. Let’s start with a basic example:

public void provideAnnotation() {
  Module cookbook = new AbstractModule() {
     @Provides
     Sugar sugar() { return new Sugar("WhiteSugar", 10.f); }

     @Provides
     Butter butter() { return new Butter("PerfectButter", 20.0f); }

     @Provides
     Flour flour() { return new Flour("GoodFlour", 100.0f); }

     @Provides
     Pastry pastry(Sugar sugar, Butter butter, Flour flour) {
        return new Pastry(sugar, butter, flour);
     }

     @Provides
     Cookie cookie(Pastry pastry) {
        return new Cookie(pastry);
     }
  };

  Injector injector = Injector.of(cookbook);
  injector.getInstance(Cookie.class).getPastry().getButter().getName());
}

Here we’ve created an AbstractModule named cookbook that contains all the required bindings, or “recipes”, for the ingredients. Call Injector.getInstance method to get an instance of the Cookie.

How does it work from the inside? Injector provides all the required dependencies for the component recursively traversing the dependencies graph in a postorder way. So it first created SugarButter and Flour, the next was Pastry, and finally a Cookie.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

(State of Kubernetes and Container Security, 2020)

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Dependency Injection Implementation in Core Java

Implement your own lightweight Dependency Injection in core Java without using any framework.

Overview

This article will guide you to understand and build a lightweight Java application using your own Dependency Injection implementation.

Dependency Injection … DI… Inversion Of Control…IoC, I guess you might have heard these names so many times while your regular routine or specially interview preparation time that you wonder what exactly it is.

but if you really want to understand how internally it works then continue reading here.
