CakePHP上层的DI容器

动机

我想通过di容器将service注入到mand和controller中。
另外，service 使用 repository 注入。
文档中并没有提到嵌套注入这种情况。

文档

book.cakephp.org/4/en/development/dependency-injection.html

如何实施服务和存储库

interface somerepository { public getall(): array;}

class somerepositoryimpl implements somerepository{ public function getall(): array { print(‘getall()’); return []; }}

class someservice{ private $somerepository; public function __construct(somerepository $somerepository) { $this->somerepository = $somerepository; } public function dosomething(): void { $this->somerepository->getall(); }}

命令

use cakemandmand;use cakeconsolerguments;use cakeconsoleconsoleio;use cakeconsoleconsoleoptionparser;class somemand extends mand{ private someservice $service; public function __construct(someservice $service) { parent::__construct(); $this->service = $service; } public static function getdescription(): string { return ‘inject service through provider’; } public function buildoptionparser(consoleoptionparser $parser): consoleoptionparser { $parser = parent::buildoptionparser($parser); return $parser; } public function execute(arguments $args, consoleio $io) { $this->service->dosomething(); }}

use cakecorecontainerinterface;use cakecoreserviceprovider;class mandserviceprovider extends serviceprovider{ protected $provides = [ somemand::class, ]; public function services(containerinterface $container): void { $container->add(somemand::class)->addargument(someservice::class); }}

控制器

use cakecontrollercontroller;class somecontroller extends controller{ public function index(someservice $service) { $service->dosomething(); print(‘index()’); }}

注册到di容器

use cakecorecontainerinterface;use cakecoreserviceprovider;class someserviceprovider extends serviceprovider{ protected $provides = [ someservice::class, ]; public function services(containerinterface $container): void { $container->add(somerepository::class, somerepositoryimpl::class); $container->add(someservice::class)->addargument(somerepository::class); }}

// Application.phpclass Application extends BaseApplication{ // … public function services(ContainerInterface $container): void { $container->addServiceProvider(new SomeServiceProvider()); $container->addServiceProvider(new ControllerServiceProvider()); } // …
