在用户实体提供Symfony2的致命错误

Question

I'm using symfony 2.3.4 and in security configuration I want to to load Security Users from the Database accordingly to this Cookbook instruction . But I only get this error:

Fatal error: Class MyApp\\AdminBundle\\Entity\\Users contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (Symfony\\Component\\Security\\Core\\User\\UserInterface::getRoles, Symfony\\Component\\Security\\Core\\User\\UserInterface::getUsername, Symfony\\Component\\Security\\Core\\User\\UserInterface::eraseCredentials) in /Volumes/Htdocs/symfony/src/MyApp/AdminBundle/Entity/Users.php

Answer 1

Symfony's security framework expects the User entity to implement the UserInterface . Implement the three methods:

public function getRoles()
public function getUsername()
public function eraseCredentials()

Answer 2

Just implement the methods from the interface. ;)
