在Symfony中使用抽象类和接口与ORM，未找到接口

I have a project which uses three different databases the first one is the main database which I can make changes to the second two belong to different projects but I need to access data in them. The following is a simplified directory structure.

Src

• AppBundle

  • Entity
    • BusinessUnitsFox
    • DriverMax
    • VehicleFox
  • Model
    • BusinessUnitInterface
    • UDODriverInterface
    • VehicleInterface

• FoxBundle

  • Entity
    • BusinessUnits
    • Vehicle
• MaxBundle
  • Entity
    • DriverMax

Below are the files for the abstract class and interface for BusinessUnits the Vehicle and Driver are similar.

<?php
// src/AppBundle/Model/BusinessUnitInterface.php

namespace AppBundle\Model;

interface BusinessUnitInterface
{
    /**
     * @return string
     */
    public function __toString();
}

The Abstract Class

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use FoxBundle\Entity\BusinessUnit as BaseBU;
use AppBundle\Model\BusinessUnitInterface;

 /**
  * @ORM\Entity
  * @ORM\Table(name="business_unit_fox")
  */
class BusinessUnitFox extends BaseBU implements BusinessUnitInterface
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
    * {@inheritDoc}
    * @see \AppBundle\Model\BusinessUnitInterface::__toString()
    */
    public function __toString() {
        return $this->getId();
    }
}

config.yml

# Doctrine Configuration

    dbal:
        default_connection: maxdb
        connections:
            maxdb:

            foxdb:

            max2db:

        resolve_target_entities:

        default_entity_manager: maxem
        entity_managers:
            maxem:
                connection: maxdb
                mappings:
                    AppBundle: 
                    BWTCalendarBundle: ~
                    BWTFMBundle: ~
                    BWTHealthCheckBundle: ~
                    BWTSkytrackBundle: ~
                    BWTTelematicsBundle: ~
            foxem:
                connection: foxdb
                mappings:
                    FoxBundle: ~
            max2em:
                connection: max2db
                mappings:
                    MaxBundle: ~

When I do A SQL call I get the following error

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'telematics.vehicle_fox' doesn't exist

So I ran doctrine:schema:update and got the following error

[Doctrine\Common\Persistence\Mapping\MappingException] Class 'AppBundle\Model\BusinessUnitInterface' does not exist

Is there anything that I am missing?

Is it possible to declare a OneToMany relationship from the abstract class?

You forgot the Interface suffix for UDODriverInterface and BusinessUnitInterface. You can follow the Symfony doc to do your mapping on Abstract classes and Interfaces

resolve_target_entities:
            AppBundle\Model\VehicleInterface: AppBundle\Entity\VehicleFox
            AppBundle\Model\UDODriverInterface: AppBundle\Entity\DriverMax
            AppBundle\Model\BusinessUnitInterface: AppBundle\Entity\BusinessUnitFox

Note also with the current declaration, your AppBundle\Entity\BusinessUnitFox class is not abstract.
