是说错误发生在第24行的ProductosController.php中，但是我看不到它：

class ProductosController扩展Controller {

}

任何的想法？谢谢

Answer 1

我在listarAction中看到你有这个：

$articulos = $em->getRepository("BDBundle:Articulos")
            ->getArticulos();

它应该是这样的：

$articulos = $em->getRepository("BDBundle:Articulos")
            ->findAll();

希望能帮助到你
