如何在Zend Framework 2中加载自定义库？

Question

我一直在关注本指南（http://socialsemanticweb.blogspot.com.au/2012/11/zend-framework-2-create-custom-library.html），但我无法让Zend看到我的图书馆（下面的错误信息）。

任何想法都可能出错？感谢

我的文件夹结构

MyLibraryController.php

<?php

namespace MyLibrary\Mvc\Controller;

use Zend\Mvc\Controller\AbstractActionController;

class MyLibraryController extends AbstractActionController {
    public function __construct() {
    }

    public function doSomething() {
        //instantiate your model here and return result
     $result = "test";
     return $result;
    }
}

我的autoload_namespaces.php （在vendor \ composer中）

<?php

// autoload_namespaces.php generated by Composer

$vendorDir = dirname(__DIR__);
$baseDir = dirname($vendorDir);

return array(
    'Zend\\' => $vendorDir . '/zendframework/zendframework/library/',
    'ZendTest\\' => $vendorDir . '/zendframework/zendframework/tests/',
    'Symfony\\Component\\Console\\' => $vendorDir . '/symfony/console/',
    'Doctrine\\ORM' => $vendorDir . '/doctrine/orm/lib/',
    'Doctrine\\DBAL' => $vendorDir . '/doctrine/dbal/lib/',
    'Doctrine\\Common' => $vendorDir . '/doctrine/common/lib/',
    'DoctrineORMModule\\' => $vendorDir . '/doctrine/doctrine-orm-module/src/',
    'DoctrineORMModuleTest\\' => $vendorDir . '/doctrine/doctrine-orm-module/tests/',
    'DoctrineModule\\' => $vendorDir . '/doctrine/doctrine-module/src/',
    'DoctrineModuleTest\\' => $vendorDir . '/doctrine/doctrine-module/tests/',
    'MyLibrary\\' => $vendorDir . '/MyLibrary/library/',
);

我的application.config.php （我只添加了MyLibrary条目。我尝试过和没有它）

<?php
return array(
    // This should be an array of module namespaces used in the application.
    'modules' => array(
        'Application',
        'DoctrineModule',
        'DoctrineORMModule',
        'Directory',
        'Helpers',
    'MyLibrary',

错误消息，但未在application.config.php中添加MyLibrary模块

Fatal error: Class 'Directory\Controller\MyLibaryController' not found in D:\work\eclipse\htdocs\directory\module\Directory\src\Directory\Controller\DirectoryController.php on line 17

application.config.php中带有MyLibrary模块条目的

错误消息

Fatal error: Uncaught exception 'Zend\ModuleManager\Exception\RuntimeException' with message 'Module (MyLibrary) could not be initialized.' in D:\work\eclipse\htdocs\directory\vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php:175 Stack trace: #0 D:\work\eclipse\htdocs\directory\vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php(149): Zend\ModuleManager\ModuleManager->loadModuleByName(Object(Zend\ModuleManager\ModuleEvent)) #1 D:\work\eclipse\htdocs\directory\vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php(90): Zend\ModuleManager\ModuleManager->loadModule('MyLibrary') #2 [internal function]: Zend\ModuleManager\ModuleManager->onLoadModules(Object(Zend\ModuleManager\ModuleEvent)) #3 D:\work\eclipse\htdocs\directory\vendor\zendframework\zendframework\library\Zend\EventManager\EventManager.php(468): call_user_func(Array, Object(Zend\ModuleManager\ModuleEvent)) #4 D:\work\eclipse\htdocs\directory\vendor\zendframework\zendframework\library in D:\work\eclipse\htdocs\directory\vendor\zendframework\zendframework\library\Zend\ModuleManager\ModuleManager.php on line 175

Answer 1

首先，它不是一个模块，因此可以通过将其添加到app config的模块数组中获得错误消息。

编辑autoload_namespaces.php以添加您的库（正如您已有的）应该可以正常工作。

也就是说，更正确的方法是将autoload密钥添加到根composer.json文件并在那里进行映射

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": ">2.2.0rc1"
    },
    "autoload": {
        "psr-0": {"MyLibrary\\": "vendor/MyLibrary/library/"}
    }
}

执行此操作后，从命令行运行composer.phar update，它将自动将您的库添加到autoload_namespaces文件中。这样做意味着每次使用composer更新其他库时都不必手动编辑文件。

错误本身

  

致命错误：第17行的D：\ work \ eclipse \ htdocs \ directory \ module \ Directory \ src \ Directory \ Controller \ DirectoryController.php中找不到类'Directory \ Controller \ MyLibaryController'

我猜测，在自动加载的情况下，你只是错过了use类中的DirectoryController语句

<?php
namespace Directory\Controller;

// be sure to use your library controller
use MyLibrary\Mvc\Controller\MyLibraryController;

class DirectoryController extends MyLibraryController
{
    //..
}
