所以，这不是我第一次创建服务，但我无法解决错误
您已请求不存在的服务"global_settings"。
我为确保服务设置正确而采取的步骤：
我的AppBundleExtension.php
namespace AppBundle'DependencyInjection;
use Symfony'Component'Config'FileLocator;
use Symfony'Component'DependencyInjection'ContainerBuilder;
use Symfony'Component'DependencyInjection'Extension'Extension;
use Symfony'Component'DependencyInjection'Loader;
class AppBundleExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader'XmlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('settings.xml');
}
}
我的settings.xml
<?xml version="1.0" encoding="UTF-8" ?>
<container
xmlns="http://symfony.com/schema/dic/services"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
<services>
<service id="global_settings" class="AppBundle'Services'GlobalSettings">
<call method="setEntityManager">
<argument type="service" id="doctrine.orm.default_entity_manager" />
</call>
</service>
</services>
</container>
我的GlobalSettings服务
namespace AppBundle'Services;
use Doctrine'ORM'EntityManager;
use Doctrine'ORM'EntityRepository;
class GlobalSettings
{
/**
* @var EntityManager
*/
protected $em;
/**
* @var EntityRepository
*/
protected $repo;
public function setEntityManager(EntityManager $em) {
$this->em = $em;
$this->repo = null;
}
/**
* @return array with name => value
*/
public function all() {
return $this->$this->getRepo()->findAll();
}
/**
* @param string $name Name of the setting.
* @return string|null Value of the setting.
* @throws 'RuntimeException If the setting is not defined.
*/
public function get($name) {
$setting = $this->$this->getRepo()->findOneBy(array(
'name' => $name,
));
if ($setting === null) {
throw $this->createNotFoundException($name);
}
return $setting->getValue();
}
/**
* @param string $name Name of the setting to update.
* @param string|null $value New value for the setting.
* @throws 'RuntimeException If the setting is not defined.
*/
public function set($name, $value) {
$setting = $this->$this->getRepo()->findOneBy(array(
'name' => $name,
));
if ($setting === null) {
throw $this->createNotFoundException($name);
}
$setting->setValue($value);
$this->em->flush($setting);
}
/**
* @return EntityRepository
*/
protected function getRepo() {
if ($this->repo === null) {
$this->repo = $this->em->getRepository('AppBundle:Settings');
}
return $this->repo;
}
/**
* @param string $name Name of the setting.
* @return 'RuntimeException
*/
protected function createNotFoundException($name) {
return new 'RuntimeException(sprintf('Setting "%s" couldn''t be found.', $name));
}
}
然后在我的控制器中，我尝试使用以下代码访问服务
$data = $this->get('global_settings')->get('paypal_email');
我做错了什么？任何帮助将不胜感激，因为我的想法。
我不断收到此错误的原因是我的服务默认设置是public: false
因此，为了解决这个问题，我需要将public属性设置为true我的服务
services:
# default configuration for services in *this* file
_defaults:
# automatically injects dependencies in your services
autowire: true
# automatically registers your services as commands, event subscribers, etc.
autoconfigure: true
# this means you cannot fetch services directly from the container via $container->get()
# if you need to do this, you can override this setting on individual services
public: false
my_service:
class: AppBundle'Service'MyService
public: true
你写道：
我为确保服务设置正确而采取的步骤
我的
AppBundleExtension.php
和：
我知道
AppBundleExtension没有加载，我需要怎么做才能加载它？我错过了什么？
所以很明显没有加载AppBundleExtension类。
根据官方文档，您应该删除文件名和类名中的Bundle：
该名称等于捆绑包名称，
Bundle后缀替换为Extension（例如，AppBundle 的扩展类将称为AppExtension，AcmeHelloBundle 的扩展类将称为AcmeHelloExtension）。
您可以更新 config.yml 文件：
imports:
- { resource: "@AppBundle/Resources/config/services.yml" }
