最近，我开始在导入脚本中使用Symfony Validator组件来验证实体是否设置了所有必填字段，并且没有“唯一约束违例”。无效的条目将被跳过并记录。
我不确定，但是这个github问题可能描述了相同的问题： https://github.com/doctrine/orm/issues/7277
验证器组件的版本为v4.2.5
并且该理论库的版本为v2.6.3
以前有人遇到这样的问题吗？我该如何解决？

在另一个进口商中，出现了一个问题，该问题也与二级缓存有关。 堆栈跟踪显示了一个区别，它使用了liip / functional-test-bundle DataCollectingValidator，因为这是我在“开发”环境中运行命令的时候。

编辑＃3：
我通过尝试调试一些奇怪的行为 教义ORM库中的UnitOfWork类。 显然，在objectIdentifiers数组中找不到对象哈希。 找不到的实体类型是与我要更新的实体的OneToOne关系。
UnitOfWork（经过修改）
/**
* Gets the identifier of an entity.
* The returned value is always an array of identifier values. If the entity
* has a composite identifier then the identifier values are in the same
* order as the identifier field names as returned by ClassMetadata#getIdentifierFieldNames().
*
* @param object $entity
*
* @return array The identifier values.
*/
public function getEntityIdentifier($entity)
{
if (!array_key_exists(spl_object_hash($entity), $this->entityIdentifiers)) {
dump([
"entity-class" => get_class($entity),
"object-hash" => spl_object_hash($entity),
"identifiers" => $this->entityIdentifiers,
]);
exit();
}
return $this->entityIdentifiers[spl_object_hash($entity)];
}
转储结果：
array:3 [
"entity-class" => "App\Entity\Model\Reference\StoreReference"
"object-hash" => "000000002f4c81ef00000000678832e6"

我也在尝试在this github repository
中重现此问题。答案 0 :(得分：0)
因此，我找到了解决该问题的方法，这是一个Doctrine错误。这不是很常规，但在此之前一直有效，直到Doctrine ORM 2.6.4发行版可用为止。
我对所有错误的OneToOne关联进行了不同的配置。通过将关系更改为ManyToOne关系，并以编程方式坚持并仅选择一个实体，我仍然具有“一对一”关系，并且我的应用程序将继续正常运行。代码：
设备实体：
/**
* Device References
*
* One Device has one Reference
*
* note: this relation is configured as a One to Many association to work around a bug in Doctrine
*
* @var ArrayCollection|DeviceReference[]
*
* @ORM\Cache(region = "rarely_changing", usage = "NONSTRICT_READ_WRITE")
* @ORM\OneToMany(targetEntity = "App\Entity\Model\Reference\DeviceReference", mappedBy = "device", cascade = {"persist", "remove"})
*/
protected $references;
/**
* Add reference
*
* @param DeviceReference $reference
*
* @return self
*/
public function addReference(DeviceReference $reference)
{
$reference->setDevice($this);
$this->references = new ArrayCollection([$reference]);
return $this;
}
/**
* Remove reference
*
* @param DeviceReference $reference
*/
public function removeReference(DeviceReference $reference)
{
$this->references->removeElement($reference);
}
/**
* Get references
*
* @return Collection|DeviceReference[]
*/
public function getReferences()
{
return $this->references;
}
/**
* Set reference
*
* @param DeviceReference $reference
*
* @return self
*/
public function setReference(DeviceReference $reference)
{
$this->addReference($reference);
return $this;
}
/**
* Get reference
*
* @return DeviceReference
*/
public function getReference()
{
if (0 === $this->references->count()) {
return null;
}
return $this->references->first();
}
DeviceReference实体：
/**
* Device
*
* One Reference has one Device
*
* note: this relation is configured as a Many to One association to work around a bug in Doctrine
*
* @var Device
*
* @ORM\Cache(region = "commonly_changing", usage = "NONSTRICT_READ_WRITE")
* @ORM\ManyToOne(targetEntity = "App\Entity\Model\Device", inversedBy = "references")
* @ORM\JoinColumn(name = "device_id", referencedColumnName = "device_id", nullable = false, unique = true)
*/
private $device;
/* ... getter and setter remain the same ... */
别忘了更新存储库中的任何自定义查询！
