我正在为symfony 2框架工作，在Controller中调用自定义Action时遇到了问题。我已经将我的应用程序连接到了一个数据库（在xampp上），对于每个表我都有Entity类。现在，我已经为其中一个实体（GuestController.php）生成了一个CRUD控制器（带有条令），我需要在其中创建一个新的Action并调用它。这是动作代码：
/**
*
* @Route("/", name="my_action")
*
*/
public function customAction() {
return new Response('<html><body>Hello</body></html>');
}
现在，如果我试图用这个链接调用它
http://localhost/TEST/web/app_dev.php/guest/guest_search_by_saloon
我获得
Unable to find Guest entity.
怎么了？
这是全控制器类
/**
* Guest controller.
*
* @Route("/guest")
*/
class GuestController extends Controller {
/**
* Lists all Guest entities.
*
* @Route("/", name="guest")
* @Method("GET")

日志上写着：
NFO - Matched route "guest_show" (parameters: "_controller": "main'dbBundle'Controller'GuestController::showAction", "id": "guest_search_by_saloon", "_route": "guest_show")
好吧，我的猜测是，首先你没有调用你向我们显示的url，因为正如日志所说，调用showAction()而不是getBySaloonAction()，这与你的错误有关，是完全合理的。
如果您注意到日志错误，您将以某种方式将guest_search_by_saloon（字符串）作为id（整数）传递，并且数据库查询使用$id = 'guest_search_by_saloon'运行，这将导致错误。
