Php MappingException:在'；中找不到目标实体UserBundle\entity\userRoles；UserBundle\Entity\User#userRoles'；

我是Symfony的初学者，我被要求使用FOSUser创建一个包含一些信息的用户实体 一切都很顺利，直到我尝试执行下面的命令行

php/bin控制台原则：模式：更新--force

这时我犯了以下错误

[条令\ORM\Mapping\MappingException]
在“UserBundle\entity\User\userRoles”中找不到目标实体UserBundle\entity\userRoles

我试图更改一些注释，但因为我不知道自己在做什么，所以这并没有真正起作用

下面是实体的片段

您的注释中似乎有一个打字错误，与
set setter/getter方法targetEntity不是
userRoles
类，而是
UserBundle\Entity\Role
类

因此，将定义更改如下：

/**
 * @ORM\ManyToMany(targetEntity="UserBundle\Entity\Role", inversedBy="user")
 * @ORM\JoinTable(name="userRoles")
 *
 */
private $userRoles;

希望这有帮助
