如何在Symfony中动态创建实体类

// src/Entity/MyEntityInterface.php

namespace App\Entity;

interface MyEntityInterface
{
    // 定义实体类的属性和方法
}

// src/Entity/MyEntityGenerator.php

namespace App\Entity;

use Doctrine\ORM\Mapping\ClassMetadata;

class MyEntityGenerator
{
    public function generate(string $className, array $fields): string
    {
        $classCode = "<?php\n\n";
        $classCode .= "namespace App\\Entity;\n\n";
        $classCode .= "use Doctrine\\ORM\\Mapping as ORM;\n\n";
        $classCode .= "class $className implements MyEntityInterface\n";
        $classCode .= "{\n";

        foreach ($fields as $fieldName => $fieldType) {
            $classCode .= "    /**\n";
            $classCode .= "     * @ORM\\Column(type=\"$fieldType\")\n";
            $classCode .= "     */\n";
            $classCode .= "    private \$$fieldName;\n\n";
        }

        $classCode .= "}\n";

        return $classCode;
    }
}

// src/Controller/MyController.php

namespace App\Controller;

use App\Entity\MyEntityGenerator;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;

class MyController extends AbstractController
{
    public function createEntity(): Response
    {
        $generator = new MyEntityGenerator();
        $className = 'MyDynamicEntity';
        $fields = [
            'name' => 'string',
            'age' => 'integer',
            // 添加更多的字段
        ];

        $classCode = $generator->generate($className, $fields);

        // 将生成的代码保存到文件或者直接使用eval函数来动态加载类

        return new Response('Entity created successfully!');
    }
}
