php - 名为 “db2” 的 Symfony2 Doctrine ORM 管理器不存在

Question

我创建 YML 实体，生成实体并配置多个连接

配置.yml

# Doctrine Configuration
doctrine:
dbal:
    default_connection: db1
    connections:
        db1:
            driver:   '%database_driver%'
            host:     '%database_host%'
            port:     '%database_port%'
            dbname:   '%database_name%'
            user:     '%database_user%'
            password: '%database_password%'
            charset:  UTF8
        db2:
            driver:   '%database_driver2%'
            host:     '%database_host2%'
            port:     '%database_port2%'
            dbname:   '%database_name2%'
            user:     '%database_user2%'
            password: '%database_password2%'
            charset:  UTF8
    orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true

我的orm.yml

TestBundle\Entity\Test:
type: entity
table: Test
id:
    id:
        type: integer
        nullable: false
        options:
            unsigned: true
        id: true
fields:
    name:
        type: string
        nullable: false
        length: 255
        options:
            fixed: false
lifecycleCallbacks: {  }

清理缓存并生成实体后，我尝试运行此代码(在命令 Controller 中)

<?php 

...

protected function execute(InputInterface $input, OutputInterface $output)
{
    $doctrine = $this->getContainer()->get('doctrine')->getManager('db2');
    //both methods cant work :( db2_entity_manager not found
    $doctrine = $this->getContainer()->get('doctrine.orm.db2_entity_manager');

    $test = $doctrine->getRepository('DionisDataBaseBundle:Test');

}

我有错误:

[InvalidArgumentException]
Doctrine ORM Manager named "db2" does not exist.

将 config.yml 更改为

 orm:
    auto_generate_proxy_classes: "%kernel.debug%"
    default_entity_manager: db1
    entity_managers:
        db1:
            connection: db1
            mappings:
                DionisDataBaseBundle: ~
        db2:
            connection: db2
            mappings:
                DionisDataBaseBundle: ~
        db3:
            connection: db2
            mappings:
                DionisDataBaseBundle: ~
