Re: SaltSource Error with tapestry-spring-security

[Ulrich Stärk]

The error says it all: You already have a service implementing SaltSource (it gets contributed 
automatically by the tapestry-spring-security module). If you want to override it, contribute to the 
AliasOverrides service:

    public static void 
contributeAliasOverrides(Configuration<AliasContribution<?>> configuration)
    {
        SaltSourceService saltSource = new SaltSourceService() {
                        public Object getSalt(UserDetails user) {
                                return null;
                        }
        };
        
        configuration.add(AliasContribution.create(SaltSourceService.class, 
saltSource));
    }
cheers,

I Just got this error and I could not figure it out yet.

java.lang.RuntimeException: Service id 'SaltSource' has already been defined
by
nu.localhost.tapestry5.springsecurity.services.SecurityModule.buildSaltSource(String)
(at SecurityModule.java:121) and may not be redefined by
nu.localhost.tapestry.acegi.services.SecurityModule.buildSaltSource(String)
(at SecurityModule.java:115). You should rename one of the service builder
methods.

here is my code in AppModule.java

    public static void bind(ServiceBinder binder)
    {
        binder.bind(SaltSourceService.class,
PlaintextSaltSourceImpl.class).withId("PlaintextSaltSource");        
    }

    public static void
contributeProviderManager(OrderedConfiguration<AuthenticationProvider>
configuration,
            @InjectService("DaoAuthenticationProvider")
AuthenticationProvider daoAuthenticationProvider) {
        configuration.add("daoAuthenticationProvider",
daoAuthenticationProvider);
    }


and my PlaintextSaltSourceImpl.java 

import org.springframework.security.userdetails.UserDetails;
import nu.localhost.tapestry5.springsecurity.services.SaltSourceService;
public class PlaintextSaltSourceImpl implements SaltSourceService {

        public Object getSalt(UserDetails user) {
                return null;
        }

}
