Question

我正在尝试实现FOSRestBundle，所以我刚刚创建了我的一流控制器。

    <?php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Controller\FOSRestController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use FOS\RestBundle\View\View;
use App\Entity\Product;

class ProductController extends FOSRestController
{
    /**
     * @Rest\Get("/product")
     */
    public function getAction()
    {
        $em = $this->getDoctrine()->getManager();
        $restresult = $em->getRepository('AppBundle:Product')->getAllProduct();
        if ($restresult === null) {
            return new View("there are no products exist", Response::HTTP_NOT_FOUND);
        }
        return $restresult;
    } // "Get products"     [GET] /product*/
}

但是Symfony服务器给我这个错误： -“未知实体名称空间别名'AppBundle'。” -“ Doctrine \ ORM \ ORMException”;

我的composer.json是：

        },
        "branch-alias": {
            "dev-master": "3.4-dev"
        }
    }

产品实体类为：

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Product
 *
 * @ORM\Table(name="Product")
 * @ORM\Entity
 */
class Product
{
    /**
     * @var integer
     *
     * @ORM\Column(name="idProduct", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $idproduct;

    /**
     * @var string
     *
     * @ORM\Column(name="productName", type="string", length=100, nullable=false)
     */
    private $productname;

    /**
     * @var boolean
     *
     * @ORM\Column(name="Purchased", type="boolean", nullable=true)
     */
    private $purchased;

    /**
     * @var \Doctrine\Common\Collections\Collection
     *
     * @ORM\ManyToMany(targetEntity="User", mappedBy="productproduct")
     */
    private $useruser;

    /**
     * Constructor
     */
    public function __construct()
    {
        $this->useruser = new \Doctrine\Common\Collections\ArrayCollection();
    }

}

，然后ProductRepository文件为：

<?php

namespace AppBundle\Repository;

use Doctrine\ORM\EntityRepository;

class ProductRepository extends EntityRepository
{
    public function getAllProduct()
    {
        $conn = $this->getEntityManager()->getConnection();
        $sql = "SELECT * from product";
        $stmt = $conn->prepare($sql);
        $stmt->execute();
        return $stmt->fetchAll();
    }
}

我也尝试替换

    $restresult = $em->getRepository('AppBundle:Product')->getAllProduct();

与

    $restresult = $em->getRepository(Product::class)->getAllProduct();

，但现在的错误是： -“类'App \ Entity \ Product'不存在” -“ Doctrine \ Common \ Persistence \ Mapping \ MappingException”

我已经尝试过其他堆栈超低用户的解决方案，但是没有任何解决方案。有人可以帮我吗？

Answer 1

use App\Entity\Product;

这应该是罪魁祸首。（在您的控制器中）

编辑：对不起，错过了第一个错误。您可以发布您的学说配置吗？是自动映射吗？

Answer 2

在ProductController文件中

代替

use App\Entity\Product;

替换为

use AppBundle\Entity\Product;

Answer 3

您的目录结构错误。 https://github.com/axeowl/projectKobe/tree/master/src

实体和仓库目录应位于AppBundle中。

未知的实体名称空间别名“ AppBundle”和“类'App \\ Entity \\ Product”不存在
