如何将自定义路由器传递给Symfony Bundle中的服务？

Question

In my Bundle I use a SessionHandler service under FooBundle/Service/SessionHandler.php

This gets passed a customized Router which extends the Symfony Router:

use FooBundle/Routing/Router
    (...)
    public function __construct(HttpUtils $httpUtils, array $options, Router $router) {
        $this->router = $router;
        $this->container = $router->getContainer();
        $this->defaultLogoutHandler = new DefaultLogoutSuccessHandler($httpUtils);
        parent::__construct($httpUtils, $options);
    }

This did work back in Symfony 2.1

With 3.1 I get an Exception:

Catchable Fatal Error: Argument 3 passed to FooBundle\Service\SessionHandler::__construct() must be an instance of FooBundle\Routing\Router, instance of Symfony\Bundle\FrameworkBundle\Routing\Router given

Here is what my services.xml looks like:

<!-- SessionHandler --> <service id="foo.sessionhandler" class="FooBundle\Service\SessionHandler"> <argument type="service" id="security.http_utils" /> <argument type="collection" id="options" /> <argument type="service" id="router" /> </service>

So how do I get this service to use my customized router?

Answer 1

The router currently being passed is the Symfony Router and hence Symfony Symfony\Bundle\FrameworkBundle\Routing\Router is given.

You must define your customised Router (FooBundle/Routing/Router) as a service and pass it's service id to the arguments list of service foo.sessionhandler to replace <argument type="service" id="router" />.
