Spring Security - Third Edition

The ConnectionSignup flow

In order to save the provider details into a local repository, we have created a ConnectionSignup object, which is a command that signs up a new user in the event that no userid can be mapped from Connection which allows for implicitly creating a local user profile from connection data during a provider sign-in attempt:

    //src/main/java/com/packtpub/springsecurity/authentication/    ProviderConnectionSignup.java    @Service     public class ProviderConnectionSignup implements ConnectionSignUp {        ...;     @Override    public String execute(Connection<?> connection) {       ...     }    }
