Symfony 4如何实现Doctrine XML ORM映射

Question

Symfony 4文档尚不清楚如何使用XML orm映射而不是注释。在官方文档中没有看到如此重要部分的详细信息，这真令人沮丧。

想象一下YourDomain\Entity\Customer域对象：

<?php declare(strict_types=1);

namespace YourDomain\Entity;

class Customer
{
    private $id;
    private $email;
    private $password;

    public function __construct(string $email)
    {
        $this->setEmail($email);
    }

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getEmail(): string
    {
        return $this->email;
    }

    public function setEmail(string $email): void
    {
        if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
            throw new \InvalidArgumentException('Not a valid e-mail address');
        }

        $this->email = $email;
    }

    public function getPassword(): ?string
    {
        return $this->password;
    }

    public function setPassword(?string $password): void
    {
        $this->password = $password;
    }
}

首先定义自己的映射：

orm:
    mappings:
        YourDomain\Entity:
            is_bundle: false
            type: xml
            // this is the location where xml files are located, mutatis mutandis
            dir: '%kernel.project_dir%/../src/Infrastructure/ORM/Mapping'
            prefix: 'YourDomain\Entity'
            alias: YourDomain

文件名必须匹配的模式[class_name].orm.xml，你的情况Customer.orm.xml。如果内部有子命名空间，例如 值对象YourDomain\Entity\ValueObject\Email，该文件必须命名ValueObject.Email.orm.xml。

映射示例：

orm:
    mappings:
        YourDomain\Entity:
            is_bundle: false
            type: xml
            // this is the location where xml files are located, mutatis mutandis
            dir: '%kernel.project_dir%/../src/Infrastructure/ORM/Mapping'
            prefix: 'YourDomain\Entity'
            alias: YourDomain

祝好运。
