来自doctrine.yaml:

# /config/packages/doctrine.yaml
doctrine:
    dbal:
        default_connection: training
        connections:
            training:
                dbname:   "training"
                driver:   "pdo_mysql"
                host:     "localhost"
                port:     "3306"
                user:     "userdb"
                password: "XXXXXXXXXX"
                charset:  UTF8
                mapping_types:
                    bit: boolean
    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        default_entity_manager: training
        entity_managers:
            training:
                connection: training
                auto_mapping: true

命令:

php bin/console doctrine:mapping:import --em=training App\Entity annotation --path=src/Entity

将Course.php实体生成到src/Entity中:

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Course
 *
 * @ORM\Table(name="course", indexes={@ORM\Index(name="id_product_idx_1", columns={"id_product"}), @ORM\Index(name="enabled_idx_1", columns={"enabled"}), @ORM\Index(name="sort_idx_1", columns={"sort"})})
 * @ORM\Entity
 */
class Course
{
    ....

运行到控制台后:

php bin/console make:entity --regenerate App

此操作失败并出现错误:

No entities were found in the "App" namespace

同样

php bin/console make:entity --regenerate App\Entity 

如果我尝试

php bin/console make:entity --regenerate App\Entity\Course

输出为

Could not find Doctrine metadata for "App\Entity\Course". Is it mapped as an entity?

我做错了什么？

Answer 1

就我而言，这是因为我写道:

php bin/console make:entity --regenerate App\Entity\Course

而不是(注意双反斜杠)

php bin/console make:entity --regenerate App\\Entity\\Course
