Php 加载我的捆绑包时,Symfony容器没有扩展
我有一个包,它在一段时间内运行得很好。但是,我必须向其添加一些自定义配置参数,因此我在bundle的config.yml中编写了一些行,如下所示:Php 加载我的捆绑包时,Symfony容器没有扩展,php,symfony,configuration,Php,Symfony,Configuration,我有一个包,它在一段时间内运行得很好。但是,我必须向其添加一些自定义配置参数,因此我在bundle的config.yml中编写了一些行,如下所示: # ... acme_my_bundle: special_params: ['param_1', 'param_2'] 该配置在捆绑包的配置类中定义: namespace ACME\MyBundle\DependencyInjection; use Symfony\Component\Config\Definition\Builder\
# ...
acme_my_bundle:
special_params: ['param_1', 'param_2']
该配置在捆绑包的配置
类中定义:
namespace ACME\MyBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
/**
* This is the class that validates and merges configuration from your app/config files
*
* To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html#cookbook-bundles-extension-config-class}
*/
class Configuration implements ConfigurationInterface {
/**
* {@inheritdoc}
*/
public function getConfigTreeBuilder() {
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('acme_my_bundle');
$rootNode
->children()
->arrayNode('special_params')
->end()
->end();
return $treeBuilder;
}
}
namespace ACME\MyBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
/**
* This is the class that loads and manages your bundle configuration
*
* To learn more see {@link http://symfony.com/doc/current/cookbook/bundles/extension.html}
*/
class ACMEMyBundleExtension extends Extension {
/**
* {@inheritdoc}
*/
public function load(array $configs, ContainerBuilder $container) {
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
// The exception is thrown here
$loader->load('config.yml');
}
}
捆绑包已在AppKernel.php
中正确注册:
public function registerBundles() {
$bundles = array(
// ...
new ACME\MyBundle(),
// ...
);
// ...
return $bundles;
}
但是,当我尝试使用我的应用程序时,我遇到了一个错误:
没有扩展能够加载“acme\u my\u bundle”(在(path\u to\u bundle)/MyBundle/DependencyInjection/./Resources/config/config.yml中)的配置。查找名称空间“acme\u my\u bundle”,未找到任何名称空间
我查找了它,但大多数结果都不令人满意-我消除了搜索过程中出现的问题:
- 配置结构不当
- 捆绑包未在应用程序内核中注册
- 配置根节点名称与从
ACMEMyBundleExtension::getAlias()返回的名称不同
var_dump($container->getExtensions()); // prints empty array - array(0) { }
它会导致验证失败,并显示消息的“无”部分-没有可用的扩展名
我尝试在ContainerBuilder::hasExtension()
中调试$this->extensions
,由于某种原因,当为供应商捆绑包启动该方法时,列表已完成,但对于我的捆绑包,列表为空。看起来我的包中的某些内容仍然没有正确定义或注册
我更改了类的名称等。为了不暴露公司代码,请原谅,如果这会引起混淆
EDIT:我没有明确提到它,但是定义了扩展
类,并且在加载时会发生异常-正如我上面所写的:
当YAML文件加载器尝试验证我的配置文件时
更清楚地说,这里是我的扩展
类:
namespace ACME\MyBundle\DependencyInjection;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
use Symfony\Component\Config\Definition\ConfigurationInterface;
/**
* This is the class that validates and merges configuration from your app/config files

*/
class Configuration implements ConfigurationInterface {
/**

public function getConfigTreeBuilder() {
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('acme_my_bundle');
$rootNode

->end();
return $treeBuilder;

class ACMEMyBundleExtension extends Extension {

public function load(array $configs, ContainerBuilder $container) {
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__ . '/../Resources/config'));
// The exception is thrown here
$loader->load('config.yml');
}
}
正如这里所解释的,您错过了bundle扩展类(ACME\MyBundle\DependencyInjection\ACMEMyExtension)。捆绑包配置的Cookbook条目为。config.yml中的键应仅命名为acme_my。仅创建
配置
类是不够的。您需要注册依赖项注入扩展,并使用其中的配置类
阅读烹饪书中的更多内容:
[Configuration]类现在可以在load()方法中用于合并配置和强制验证(例如,如果传递了附加选项,将引发异常)
namespace Acme\MyBundle\DependencyInjection;
使用Symfony\Component\HttpKernel\DependencyInjection\Extension;
使用Symfony\Component\DependencyInjection\ContainerBuilder;
类AcmeMyBundleExtension扩展了扩展
{
公共函数加载(数组$configs,ContainerBuilder$container)
{
$configuration=新配置();
$config=$this->processConfiguration($configuration,$configs);
// ...
}
}
根据约定命名扩展类将使其自动加载。有关在中创建DIC扩展类的详细信息。您还可以手动启用扩展,请参阅。在$rootNode=$treeBuilder->root('BUNDLE\CONFIG\u KEY')的ACME\MyBundle\DependencyInjection\configuration
中检查您的配置读取器代码>
BUNDLE\u CONFIG\u键应为:
- 有效(在
ACME\MyBundle\DependencyInjection\Configuration
和您的config.yml
- 对于应用程序来说是唯一的
另外,请检查您是否以正确的方式定义了捆绑包配置-它应该添加到app/config/*.yml
(全局配置文件之一)。也许你已经在其他自定义包配置文件中添加了acme\u my\u bundle
config?扩展名已经定义,我已经更新了我的问题,特别提到它,根据我回答中的链接,尝试更改命名约定。ACMEMyBundleExtension到ACMEMyExtension,acme\u my bundle到acme\u my。我认为你的扩展名Symfony由于某些原因没有加载sion。扩展名
已经定义,我已经更新了我的问题,特别提到了它。请验证您的命名,或者尝试手动启用扩展名:就是这样!我在本地捆绑包config.yml
中添加了配置,这是一个多么愚蠢的错误。。。
