I provide you the code for those which want to use a converter :

<pre><code>use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\ParamConverterInterface;
use Symfony\Component\HttpFoundation\Request;

/**
 * Put specific attribute parameter to query parameters
 */
class QueryStringConverter implements ParamConverterInterface{
 public function supports(ParamConverter $configuration) {
 return 'querystring' == $configuration-&gt;getConverter();
 }

 public function apply(Request $request, ParamConverter $configuration) {
 $param = $configuration-&gt;getName();
 if (!$request-&gt;query-&gt;has($param)) {
 return false;
 }
 $value = $request-&gt;query-&gt;get($param);
 $request-&gt;attributes-&gt;set($param, $value);
 }
}
</code></pre>

services.yml :

<pre><code>services:
 querystring_paramconverter:
 class: AppBundle\Extension\QueryStringConverter
 tags:
 - { name: request.param_converter, converter: querystring }
</code></pre>

In your controller:

<pre><code>/**
 * @Route("/test")
 * @ParamConverter("name", converter="querystring")
 */
public function action(Request $request, $name) {
 return new Response(print_r($name, true));
}
</code></pre>

blocks|key|1281800|text|我没有检查过，但是FOSRestBundle似乎提供了@QueryParam注释，它是这样做的：listener.html|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1281801|entityMap|0|LINK|mutability|MUTABLE|url|http://symfony.com/doc/current/bundles/FOSRestBundle/param_fetcher_listener.html^0|1C|D|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I havn't checked, but it seems that the FOSRestBundle provides the @QueryParam annotation which does that :

blocks|key|2440548|text|一个改进的解决方案基于雷米的答案，它将参数映射到一个实体：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2440549|<?php

An improved solution based on Remy's answer which will map the parameter to an entity :

<pre><code>&lt;?php
namespace AppBundle\Extension;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\DoctrineParamConverter;

/**
 * Put specific attribute parameter to query parameters
 */
class QueryStringConverter extends DoctrineParamConverter {

 protected function getIdentifier(Request $request, $options, $name)
 {
 if ($request-&gt;query-&gt;has($name)) {
 return $request-&gt;query-&gt;get($name);
 }

 return false;
 }

}
</code></pre>

services.yml:

<pre><code>services:
 querystring_paramconverter:
 class: MBS\AppBundle\Extension\QueryStringConverter
 arguments: ['@doctrine']
 tags:
 - { name: request.param_converter, converter: querystring }
</code></pre>

in your controller:

<pre><code>/**
 * @Route("/test")
 * @ParamConverter("myobject")
 */
public function action(Request $request, AnyEntity $myobject) {
 return new Response(print_r($myobject-&gt;getName(), true));
}
</code></pre>

blocks|key|1884253|text|与#2一样，要解决私有方法(getIdentifier)，首先设置属性并正常执行(父方法：：apply)。在Symfony+4.4上测试|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1884254|<?php

namespace+App\FrameworkExtra\Converters;

use+Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;

like #2, To solve private method (getIdentifier) first set attributes and execute normally (parent::apply). Tested on Symfony 4.4
<pre class="lang-php prettyprint-override"><code>&lt;?php

namespace App\FrameworkExtra\Converters;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\DoctrineParamConverter;
use Symfony\Component\HttpFoundation\Request;

class QueryStringEntityConverter extends DoctrineParamConverter 
{
 public function supports(ParamConverter $configuration)
 {
 return 'querystringentity' == $configuration-&gt;getConverter();
 }

 public function apply(Request $request, ParamConverter $configuration)
 {
 $param = $configuration-&gt;getName();
 if (!$request-&gt;query-&gt;has($param)) {
 return false;
 }
 $value = $request-&gt;query-&gt;get($param);
 $request-&gt;attributes-&gt;set($param, $value);

 return parent::apply($request, $configuration);
 }
}
</code></pre>

In Symfony2, the route parameters can be automatically map to the controller arguments, eg: <a href="http://a.com/test/foo" rel="noreferrer">http://a.com/test/foo</a> will return "foo"

<pre><code> /**
 * @Route("/test/{name}")
 */
 public function action(Request $request, $name) {
 return new Response(print_r($name, true));
 }
</code></pre>

see <a href="http://symfony.com/doc/current/book/routing.html#route-parameters-and-controller-arguments" rel="noreferrer">http://symfony.com/doc/current/book/routing.html#route-parameters-and-controller-arguments</a>

But I want to use query string instead eg: <a href="http://a.com/" rel="noreferrer">http://a.com/</a>test?name=foo

How to do that ?
For me there are only 3 solutions:

<ul>
<li>re-implement <a href="http://api.symfony.com/2.7/Symfony/Component/HttpKernel/Controller/ControllerResolverInterface.html" rel="noreferrer">ControllerResolverInterface</a></li>
<li>use a custom ParamConverter</li>
<li>$name = $request->query->get('name');</li>
</ul>

Is there another solution ?
