当我尝试请求在奏鸣曲中列出对象时出现此错误：

您请求了一个不存在的服务“”。

这是我的 config.yml：

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: services.xml }

framework:
    #esi:             ~
    #translator:      { fallback: %locale% }
    translator:      ~
    secret:          %secret%
    router:
        resource: "%kernel.root_dir%/config/routing.yml"
        strict_parameters: %kernel.debug%
    form:            true

# Doctrine Configuration

sonata_admin:
    title:      Sonata Project
    title_logo: /bundles/sonataadmin/logo_title.png

这是我的 services.xml：

<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/services-1.0.xsd">
    <services>
       <service id="sonata.admin.tag_admin" class="Sonata\DefaultBundle\Admin\TagAdmin">
          <tag name="sonata.admin" manager_type="orm" group="Posts" label="Blog"/>
          <argument />
          <argument>Sonata\DefaultBundle\Admin\TagAdmin</argument>
          <argument>SonataAdminBundle:CRUD</argument>
          <call method="setTranslationDomain">
              <argument>fjaksa</argument>
          </call>
      </service>
   </services>
</container>

【解决方案1】：

这个错误意味着你没有为当前控制器“”服务（控制器也是空的^_^）

在stackoverflow上搜索例子有十几个例子！！！

也许这项服务会起作用：

<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/services-1.0.xsd">
<services>
   <service id="sonata.admin.tag_admin" class="Sonata\DefaultBundle\Admin\TagAdmin">
      <tag name="sonata.admin" manager_type="orm" group="Posts" label="Blog"/>
      <argument />
      <argument>Sonata\DefaultBundle\Admin\TagAdmin</argument>
      <argument />
      <call method="setTranslationDomain">
          <argument>fjaksa</argument>
      </call>
  </service>
