According to your code, you already have an <code>EntityManager</code> injected. You don't need to call <code>$em = $this-&gt;get('doctrine')-&gt;getEntityManager()</code> — just use <code>$this-&gt;em</code>.

If you don't inject an <code>EntityManager</code> already, read <a href="http://symfony.com/doc/current/book/service_container.html#service-parameters" rel="noreferrer">this</a>.

UPDATE:

You need to make the container inject an <code>EntityManager</code> into your service. Here's an example of doing it in <code>config.yml</code>:

<pre><code>services:
 your.service:
 class: YourVendor\YourBundle\Service\YourService
 arguments: [ @doctrine.orm.entity_manager ]
</code></pre>

I prefer to <a href="http://symfony.com/doc/current/cookbook/bundles/extension.html#configuring-services-and-setting-parameters" rel="noreferrer">define</a> bundles' services in their own <code>services.yml</code> files, but that's a bit more advanced, so using <code>config.yml</code> is good enough to get started.

blocks|key|715854|text|为了方便地访问Entitymanager，请使用以下方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|715855|//services.yml

For easily accessing the Entitymanager use the following one:

<pre><code>//services.yml
 your service here:
 class: yourclasshere
 arguments: [@doctrine.orm.entity_manager]
</code></pre>

And in the class itself:

<pre><code>class foo
{
 protected $em;



 public function __construct(\Doctrine\ORM\EntityManager $em)
 {
 $this-&gt;em = $em;
 }

 public function bar()
 {
 //Do the Database stuff
 $query = $this-&gt;em-&gt;createQueryBuilder();

 //Your Query goes here

 $result = $query-&gt;getResult();
 }
}
</code></pre>

blocks|key|500401|text|对于使用symfony3的任何人:为了在服务容器中使用原理，您需要在config/services.yml中执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|500402|servicename_manager:

for anyone who works with symfony3: u need to do the following inside config/services.yml in order to use doctrine in Service Container:

<pre><code>servicename_manager:

I am using Symfony 3.4. If you want to create a service in a bundle this works for me:

<pre><code>services:
 Vendor\YourBundle\Service\YourService:
 arguments:
 $em: '@doctrine.orm.entity_manager'
</code></pre>

In your Service.php

<pre><code>&lt;?php

namespace Hannoma\ElternsprechtagBundle\Service;

use Doctrine\ORM\EntityManager;
use Hannoma\ElternsprechtagBundle\Entity\Time;

class TimeManager
{
 protected $em;

 public function __construct(EntityManager $em)
 {
 $this-&gt;em = $em;
 }

}
</code></pre>

How do I use Doctrine in a service container?

The Code just causes an error message "Fatal error: Call to undefined method ...::get()".

<pre><code>&lt;?php

namespace ...\Service;

use Doctrine\ORM\EntityManager;
use ...\Entity\Header;

class dsdsf
{ 
 protected $em;

 public function __construct(EntityManager $em)
 {
 $this-&gt;em = $em;
 }

 public function create()
 {
 $id = 10;
 $em = $this-&gt;get('doctrine')-&gt;getEntityManager();
 $em-&gt;getRepository('...')-&gt;find($id);
 }
}
</code></pre>

services.yml

<pre><code>service:
 site:
 class: ...\Service\Site
</code></pre>
