我的错误：

ContextErrorException：Catchable Fatal Error：传递给的参数1 Agc \ ManagerBundle \ Lib \ grafica :: __ construct（）必须实现接口 Symfony \ Component \ DependencyInjection \ ContainerInterface，没有给出，呼唤 C：\瓦帕\ WWW \伽利略\ SRC \ AGC \ BackendBundle \控制器\ DefaultController.php 在第20行并在中定义 C：\ wamp \ www \ galileo \ src \ Agc \ ManagerBundle \ Lib \ grafica.php第10行

我的班级grafica：

<?php
namespace Agc\ManagerBundle\Lib;

use Symfony\Component\DependencyInjection\ContainerInterface;
/**
 * @Route(service="srv_grafica")
 */
class grafica
{
    private $container, $conn, $bdnmgi;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
        $this->conn = $this->getConn();
        $this->bdnmgi = $this->getBd();
    }

    public function getConn(){
        return $this->container->get('database_connection');
    }
    public function getBd(){
        return $this->container->get('security.context')->getToken()->getUser()->getAdministracion()->getNombreEsquemamgi();
    }

\ ManagerBundle \资源\配置\ services.yml

services:
    srv_grafica:
        class: Agc\ManagerBundle\Lib\grafica
        arguments:
            - '@service_container'

我的DefaultController：

class DefaultController extends Controller
{
    public function dashboardAction(Request $peticion)
    {
        $em = $this->getDoctrine()->getManager('customer_1');
        $user= $this->get('security.context')->getToken()->getUser();
        $esquema = $user->getAdministracion()->getNombreEsquemamgi();
        var_dump($esquema);
        $grafica = new grafica();

Answer 1

您需要将容器传递给您的服务，在一个示例下面如何在您的services.yml中执行此操作

services:

    srv_grafica:
        class: Agc\ManagerBundle\Lib\grafica
        arguments:
            - '@service_container'

Answer 2

那是错的：

$grafica = new grafica();

应该是：

$grafica = $this->get('srv_grafica');

在简单的bundle类中使用容器不能在Symfony 2中工作
