如何在 laravel 4 中自动加载“库”？

Question

我在 app 文件夹中创建了一个库文件夹来添加我的应用程序库。我已经更新了应用程序配置文件和 composer.json 以自动加载该文件夹，但是当我运行命令 composer dump-autoload 时，我收到下一个错误：

{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","message":"Class 'App\\Libraries\\Search\\SearchServiceProvider' not found","file":"D:\\Users\\Miguel Borges\\Documents\\Trabalhos\\Tese\\portal\\bootstrap\\compiled.php","line":4130}}PHP Fatal error: Class 'App\Libraries\Search\SearchServiceProvider' not found in D:\Users\Miguel Borges\Documents\Trabalhos\Tese\portal\bootstrap\compiled.php on line 4130 [Finished in 1.1s with exit code 255]

我的应用文件夹树：

app
| ...
+ libraries
| + search
| | - Search.php
| | - SearchFacade.php
| | - SearchServiceProvider.php
| + lib2
| | - ...
| + lib3
| | - ...
| | - Theme.php
| - ...
- filters.php
- routes.php

SearchServiceProvider.php

namespace App\Libraries\Search;

use Illuminate\Support\ServiceProvider;

class SearchServiceProvider extends ServiceProvider {

    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register()
    {
        $this->app['search'] = $this->app->share(function($app)
        {
            return new Search;
        });
    }

}

composer.json

    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/libraries",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
        // ,
  //       "psr-0": {
  //           "app": "app/libraries"
  //       }
    },

基本上，我需要自动加载“库”文件夹中的所有库。

Answer 1

您应该为您的应用程序创建一个顶级命名空间。

然后将所有库你代码放在该命名空间下。 注意：任何第三方库都应该（希望）通过 Composer 安装，因此有自己的命名空间/自动加载设置。

您的目录结构将是：

libraries
    Myapp
        Search (note directory is capitalized)
            Search.php
            SearchFacade.php
            SearchServiceProvider.php
        AnotherLib

然后您的类将遵循该命名空间：

文件：Myapp/Search/Search.php：

<?php namespace Myapp\Search;

class Search { ... }

最后，您的自动加载设置：

"autoload": {
    "classmap": [
        "app/commands",
        "app/controllers",
        "app/models",
        "app/libraries",
        "app/database/migrations",
        "app/database/seeds",
        "app/tests/TestCase.php"
    ]
    ,
    "psr-0": {
         "Myapp": "app/libraries"
    }
},
