我得到了这个错误:
警告:Doctrine'ORM'EntityRepository::__construct()缺少参数1
我使用phpstorm进行编码，在TestController.php
new ProductRepository();
用下划线表示:
必需参数$em缺少less.
调用参数类型与声明的不兼容。
但是我还没有使用$em参数。
我使用了3个文件:
AppBundle
|__Controller
| |__ TestController.php
|__Entity
|_______ Product.php
|_______ ProductRepository.php
TestController.php:
<?php
namespace AppBundle'Controller;
use Sensio'Bundle'FrameworkExtraBundle'Configuration'Route;
use Symfony'Bundle'FrameworkBundle'Controller'Controller;
use Doctrine'ORM'EntityRepository;
use AppBundle'Entity'ProductRepository;
use Symfony'Component'HttpFoundation'Response;
class TestController extends Controller
{
/**
* @Route("/test", name="test")
*/
public function indexAction()
{
$pr = new ProductRepository();
return new Response('OK '.$pr->test());
}
}
Product.php:
<?php
// src/AppBundle/Entity/Product.php
namespace AppBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
/**
* @ORM'Entity
* @ORM'Table(name="product")
* @ORM'Entity(repositoryClass="AppBundle'Entity'ProductRepository")
*/
class Product
{ /* ......CODE ...*/}
ProductRepository.php:
namespace AppBundle'Entity;
use Doctrine'ORM'EntityRepository;
class ProductRepository extends EntityRepository
{
public function test()
{
return 'hello';
}
}
通过学说服务获取知识库，控制器通过getDoctrine方法返回学说服务
public function indexAction()
{
$pr = $this->getDoctrine()->getRepository('AppBundle:Product');
return new Response('OK '.$pr->test());
}
您不应该直接创建存储库。使用EntityManager。您可以尝试以下代码:
class TestController extends Controller
{
private $entityManager;
public function __construct('Doctrine'ORM'EntityManager $entityManager)
{
$this->entityManager = $entityManager;
}
/**
* @Route("/test", name="test")
*/
public function indexAction()
{
$pr = $this->entityManager->getRepository('AppBundle'Entity'ProductRepository');
return new Response('OK '.$pr->test());
}
}
