Laravel 类和接口注入相关的代码

class myClass {

 public function show() {
  echo __FUNCTION__.' Hello World';
 }
}

Route::get('test/ioc', 'TestController@index');

class TestController extends Controller
{
 public function index(myClass $myClass) {
  $myClass->show();
 }
}

class myClass implements like {

 public function play() {
  // TODO: Implement play() method.
  echo __FUNCTION__.' Hello Play';
 }
}

interface like {
 public function play();
}

class TestController extends Controller
{
 public function index(like $like) {
  $like->play();
 }
}

Target [App\library\like] is not instantiable.

class LikeServiceProvider extends ServiceProvider
{
 public function boot()
 {
  //
 }
 public function register()
 {
  //
  $this->app->bind('App\library\like', 'App\library\myClass');
 }
}
