DynamicSecurityFilter是否加上判重比较？

private static final String FILTER_APPLIED = "__spring_security_demoFilter_filterApplied";

if (servletRequest.getAttribute(FILTER_APPLIED) != null) {
        filterChain.doFilter(servletRequest, servletResponse);
        return ;
    }
    //do something
    servletRequest.setAttribute(FILTER_APPLIED,true);
    filterChain.doFilter(servletRequest, servletResponse);
