using email and username both as login in spring security plugin in Grails

Question

I am using spring security plugin in my Grails application and i would like the users registered to login into the application with username or email address provided during the registration process.(just like fb)

I have already looked into the web and concerned Grails docs ::: http://grails-plugins.github.io/grails-spring-security-core/docs/manual/guide/single.html#4.1%20Person%20Class

but could not find any solution.

Any help would be highly appreciated.

Thanks in advance

Answer 1

From a spring-security point of view, what you should do is implement your own org.springframework.security.core.userdetails.UserDetailsService

public class MyUserServiceImpl implements UserDetailsService{

    @Autowired
    private AdminUserDao dao;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {

    ... Here comes your logic to get your the user based on email or userid ...

    }
}

in your spring config you have to reference your UserDetails class:

<authentication-manager>
    <authentication-provider user-service-ref="myUserServiceImpl" />
</authentication-manager>
