**隨著 PHP 8 的新特性增加，你也許已經不需要此套件了，可參考 [Constructor Property Promotion](https://www.php.net/releases/8.0/en.php#constructor-property-promotion) 的作法**

Laravel 的依賴注入很棒，但我們讓他更好！

關於

[](#關於)

想想看，當你專案越來越大，一定有遇過又臭又長的建構子：

```
use A2Workspace\AutoMount\AutoMountDependencies;

class ProductController extends Controller
{
    protected ProductService $productService;

    protected ProductRepository $productRepository;

    protected ProductStockManager $productStockManager;

    public function __construct(
        ProductService $productService,
        ProductRepository $productRepository,
        ProductStockManager $productStockManager
    ) {
        $this->productService = $productService;
        $this->productRepository = $productRepository;
        $this->productStockManager = $productStockManager;
    }

    public function __invoke(Request $request)
    {
        $this->productService->doSomething();
    }
}
```

透過 `AutoMountDependencies` 特性自動掛載依賴，讓我們省略繁雜的綁定過程。

```
use A2Workspace\AutoMount\AutoMountDependencies;

class ProductController extends Controller
{
    use AutoMountDependencies; // Add this.

    protected ProductService $productService;

    protected ProductRepository $productRepository;

    protected ProductStockManager $productStockManager;

    // We don't need the constructor anymore...

    public function __invoke(Request $request)
    {
        $this->productService->doSomething(); // Still works!
    }
}
```

安裝
--

[](#安裝)

此套件基於 PHP 7.4 的 [Typed Properties](https://www.php.net/manual/en/migration74.new-features.php#migration74.new-features.core.typed-properties)新功能，請確保你的 PHP 更新到最新版本。

```
composer require a2workspace/laravel-automount
```

如何使用
----

[](#如何使用)

僅須在目標類別上使用 `AutoMountDependencies` 特性:

```
use A2Workspace\AutoMount\AutoMountDependencies;

class PaymentService
{
    use AutoMountDependencies;
}
```

接著，有型別定義的類別屬性就會在建構時自動做依賴注入。

```
use A2Workspace\AutoMount\AutoMountDependencies;

class PaymentService
{
    use AutoMountDependencies;

    protected PaymentGatewayFactory $factory;
}
```

**注意**: 考慮到繼承，請避免使用 `private` 私有在要被處理的屬性上。

### 不會被處理的屬性

[](#不會被處理的屬性)

以下類型的屬性會被略過處理:

1. 基本型別 (int, float, bool, array ...)
2. 未定義型別的屬性
3. 定義為 [Nullable](https://www.php.net/manual/en/language.types.declarations.php#language.types.declarations.nullable) 的屬性
4. 有初始值的屬性

```
use A2Workspace\AutoMount\AutoMountDependencies;

class PaymentService
{
    use AutoMountDependencies;

    protected int $amount; // Pass.

    protected array $gateways; // Pass.

    protected $something; // Pass.

    protected ?PaymentGateway $gateway = null; // Pass.

    protected PaymentGatewayFactory $factory; // Do inject.
}
```

限制

[](#限制)

### 覆寫建構子

[](#覆寫建構子)

`AutoMountDependencies` 特性中定義了在建構子中執行依賴掛載的動作。當你需要覆寫 (Override) `__construct()` 時，記得手動呼叫 `mountDependencies()` 方法。

```
use A2Workspace\AutoMount\AutoMountDependencies;

class PaymentService
{
    use AutoMountDependencies;

    public function __construct()
    {
        $this->mountDependencies(); // Add this line.

        // ...
    }
}
```

### 避免私有屬性

[](#避免私有屬性)

當型別屬性被定義為私有，會導致繼承後的子類別，在建構時無法寫入屬性而造成錯誤。

請謹慎使用 `private` ，或將屬性定義為 [Nullable](https://www.php.net/manual/en/language.types.declarations.php#language.types.declarations.nullable) 。

```
use A2Workspace\AutoMount\AutoMountDependencies;

abstract class BasePaymentGateway
{
    use AutoMountDependencies;

    private PaymentServiceProvider $service;
}

class PaymentGateway extends BasePaymentGateway
{
    // ...
}

$gateway = new PaymentGateway; // 拋出 PaymentGateway::$service 未被初始之錯誤
```
