How to Define Non Shared Services
In the service container, all services are shared by default. This means that
each time you retrieve the service, you'll get the same instance. This is
often the behavior you want, but in some cases, you might want to always get a
new instance.
In order to always get a new instance, set the shared setting to false
in your service definition:
- YAML
| # app/config/services.yml
services:
app.some_not_shared_service:
class: ...
shared: false
# ...
|
- XML
| <!-- app/config/services.xml -->
<services>
<service id="app.some_not_shared_service" class="..." shared="false" />
</services>
|
- PHP
| // app/config/services.php
use Symfony\Component\DependencyInjection\Definition;
$definition = new Definition('...');
$definition->setShared(false);
$container->setDefinition('app.some_not_shared_service', $definition);
|
Now, whenever you call $container->get('app.some_not_shared_service') or
inject this service, you'll receive a new instance.
