<?php/* * example演示类 */namespace AppHttpModels;class Example extends IlluminateDatabaseEloquentModel {    public function sayHello() {        echo "hello,this is a model say";    }}

<?php/** * Example服务提供者 */namespace AppProviders;use IlluminateSupportServiceProvider;use AppHttpModelsExample;class ExampleServiceProvider extends ServiceProvider {    /**     * 在容器中注册绑定.     *     * @return void     */    public function register() {        $this->app->singleton('AppHttpModelsExample', function($app) {            return new Example($app);        });    }}

$app->register(AppProvidersExampleServiceProvider::class);

<?php/** * Example实例Controller */namespace AppHttpControllers;use AppHttpModelsExample;class ExampleController extends Controller {    public function __construct(Example $example) {        $this->example= $example;    }    public function index() {        $this->example->sayHello();    }
