How to implement AuditorAware with Spring Data JPA and Spring Security?

Question

We use Hibernate/JPA, Spring, Spring Data and Spring Security in our application. I have a standard User entity which is mapped using JPA. Further, I have a U

To be honest, You do not actually require one another entity. For example, I had similar problem and I resolved it in following way:

public class SpringSecurityAuditorAware implements AuditorAware, ApplicationListener {
    private static final Logger LOGGER = getLogger(SpringSecurityAuditorAware.class);
    @Autowired
    SUserRepository repository;
    private SUser systemUser;

    @Override
    public SUser getCurrentAuditor() {
        final Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        SUser principal;
        if (authentication == null || !authentication.isAuthenticated()) {
            principal = systemUser;
        } else {
            principal = (SUser) authentication.getPrincipal();
        }
        LOGGER.info(String.format("Current auditor is >>> %s", principal));
        return principal;
    }

    @Override
    public void onApplicationEvent(final ContextRefreshedEvent event) {
        if (this.systemUser == null) {
            LOGGER.info("%s >>> loading system user");
            systemUser = this.repository.findOne(QSUser.sUser.credentials.login.eq("SYSTEM"));
        }
    }
}

Where SUser is both the class which I use for auditing as well as for the security. I had maybe different use case than Yours and my approach will be deleted after, but it can be resolved like this.
