我已经在我的问题上工作了7天但我无法找到解决方案。问题是：为什么拳击手的数据会保存到桌子而不是Boxer？
拳击手的数据模型;
<?php
namespace boxebd\BoxingBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Boxer
*
* @ORM\Table(name = "boxer")
* @ORM\Entity
*/
class Boxer extends Person
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="TABLE")
*/
private $id;
/**
* @var \DateTime
*
* @ORM\Column(name="career_start", type="date")
*/
private $careerStart;
/**
* @var \DateTime
*
* @ORM\Column(name="career_end", type="date")
*/
private $careerEnd;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set careerStart
*
* @param \DateTime $careerStart
* @return Boxer
*/
public function setCareerStart($careerStart)
{
$this->careerStart = $careerStart;
return $this;
}
/**

* @return \DateTime
*/
public function getCareerStart()
{
return $this->careerStart;
}
/**

*/
public function setCareerEnd($careerEnd)
{
$this->careerEnd = $careerEnd;
return $this;
}
/**

public function getCareerEnd()
{
return $this->careerEnd;

public function __toString() {
parent::__toString() ." ". $this->careerStart;
}
}

private $dob;
public function setId($id){
$this->id = $id;
return $this;
}
/**

*/
public function getId()
{
return $this->id;
}
/**

*/
public function setFirstname($firstname)
{
$this->firstname = $firstname;
return $this;
}
/**

*

*/
public function getFirstname()
{
return $this->firstname;
}
/**

*

* @return Person
*/
public function setLastname($lastname)
{
$this->lastname = $lastname;
return $this;
}
/**

*/
public function getLastname()
{
return $this->lastname;
}
/**

*/
public function setDob($dob)
{
$this->dob = $dob;
return $this;
}
/**

*/
public function getDob()
{
return $this->dob;
}
public function __toString(){
return $this->firstname." ".$this->lastname;
}
}
我不会发布PersonController和PersonType的代码，因为我相信他们的代码是正确的。我认为错误可能出现在BoxerController或BoxerType中。

我可以成功创建一个新的Person条目但我无法创建一个新的Boxer条目，因为消息错误说：
执行＆＃39; INSERT INTO person（firstname，lastname，dob，class_name）VALUES（？，？，？，？）＆＃39;使用params [null，null，null，＆＃34; boxer＆＃34;]：
SQLSTATE [23000]：违反完整性约束：1048列＆＃39;名字＆＃39;不能为空＆＃34;
该消息没有意义，因为我已经有两个Person条目，而且我不想创建另一个Person条目。我想要的是使用人员ID创建一个新的Boxer条目到一个新的Boxer条目。我在O / R Mapping上使用类表继承。
