如何通过API JSON SYMFONY 3持久化数据

// 定义实体类
namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="product")
 */
class Product
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string")
     */
    private $name;

    // 其他属性和方法...

    // Getter和Setter方法...
}

// 创建控制器
namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use AppBundle\Entity\Product;

class ApiController extends Controller
{
    public function createProductAction(Request $request)
    {
        $data = json_decode($request->getContent(), true);

        $product = new Product();
        $product->setName($data['name']);

        $em = $this->getDoctrine()->getManager();
        $em->persist($product);
        $em->flush();

        return new Response('Product created', 201);
    }

    // 其他API操作...
}
