不推荐使用的用户：不建议使用创建Doctrine \ ORM \ Mapping \ UnderscoreNamingStrategy而不知道其编号的方法已被弃用，并将在Doctrine ORM 3.0中将其删除。
不赞成创建Doctrine \ ORM \ Mapping \ UnderscoreNamingStrategy而不通知其编号的做法已被弃用，并将在Doctrine ORM 3.0中将其删除。

class UnderscoreNamingStrategy implements NamingStrategy

private const NUMBER_AWARE_PATTERN = '/(?<=[a-z0-9])([A-Z])/';
/**
* Underscore naming strategy construct.

* @param int $case CASE_LOWER | CASE_UPPER
*/
public function __construct($case = CASE_LOWER, bool $numberAware = false)
{
if (! $numberAware) {
