問題描述

Event事件處理類里無法使用依賴注入, 然而把這個依賴注入放在controller下就能正常訪問

程序代碼

# 事件注冊
\plugin\foo\config\event.php
    return [
        'user.register' => [
            [\plugin\foo\app\event\User::class, 'register'],
        ]
    ];

# 需要被注入依賴的類
\plugin\foo\app\service\FooService.php
    class FooService {

        public function test() {
            var_dump("----------------");
        }

    }

# 事件處理類
\plugin\foo\app\event\User.php
    class User
    {
        /**
         * @Inject
         * @var FooService
         */
        protected $fooService;

        /**
         * 用戶注冊成功后的事件
         * @param array $user 用戶信息
         * @return void
        */
        public function register(array $user)
        {
            var_dump("用戶注冊callback");
            $this->fooService->test();   //這里的$this->fooService 為空
        }
    }

# 正常訪問
\plugin\foo\app\controller\UserController.php
    class UserController
    {
        /**
         * @Inject
         * @var FooService
         */
        protected $fooService;

        public function index(Request $request) {
            $this->fooService->test();   //這里就可以正常執(zhí)行
        }

    }
