Symfony2 - PUGXMultiUserBundle - 无法实例化抽象类

Question

我尝试安装PUGXMultiUserBundle，现在当我尝试加载应用程序的所有步骤（仅主要位置：http://localhost/jpp/web/app_dev.php）时，我总是收到以下错误：

致命错误：无法在C：\ xampp \ htdocs \ JPP \ vendor \ symfony \ symfony \ src \ Symfony \ Component \ Security \ Core \ Authentication \ Token \ AbstractToken.php中实例化抽象类JPP \ UserBundle \ Entity \ User在第155行

我尝试了几件事没有成功，请你能帮帮我吗？您可以在下面找到我的实体课程。我能够使用GIT在数据库中创建所有表。租赁类位于：JPP / UserBundle / Entity。如果您需要更多文件，请告诉我......非常感谢!!!

Answer 1

错误说：

Fatal error: Cannot instantiate abstract class JPP\UserBundle\Entity\User in C:\xampp\htdocs\JPP\vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Token\AbstractToken.php on line 155

这意味着Symfony尝试实例化你的User类（例如新的User（））但是因为这个类是抽象的而失败。所以，只需删除抽象定义。

替换

abstract class User extends BaseUser

带

class User extends BaseUser
