You can try setting your custom AuthenticationToken token in your authentication filter, for example:

public class AuthenticationFilter extends GenericFilterBean {
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        final String authTokenHeader = ((HttpServletRequest)request).getHeader(Constants.AUTH_HEADER_NAME);

        if (authTokenHeader != null) {
            SecurityContextHolder.getContext().setAuthentication(createAuthenticationToken(authTokenHeader));
        }

        chain.doFilter( request, response );
    }
}
