生成的ID总是0

Question

我宣布我的实体的ID：

/** 
* @ORM\Id @ORM\Column(type="integer") @ORM\GeneratedValue 
*/ 
protected $id; 

但每次我尝试它我的数据库表格后保存，我得到“0”，其结果得出：Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY'

我存储逻辑如下：

public function CallManager($data) 
    { 
    $callRequested= new CallRequested; 
    $callRequested-> setClientContact($data['clientContact']); 
    $callRequested-> setProvider($data['provider']); 
    $callRequested-> setCallCenter($data['callCenterContact']); 
    $whenCall= $data['schedule']; 
    $language= $data['language']; 
    $date = new \DateTime(); 
    $callRequested-> setRequestTime($date); 

    var_dump($data); 

    $this->entityManager->persist($callRequested); 
    $this->entityManager->flush(); 

    } 

我该怎么办？

你需要告诉它，你希望它自动递增，像这样：

/** 
* @ORM\Id 
* @ORM\GeneratedValue(strategy="AUTO") 
* @ORM\Column(type="integer") 
*/ 
private $id;
