我正在使用此资源服务器来授权请求，但每当它尝试计算表达式-“@ipwhitelistingprovider.isitvalid（request）”时，它会给出错误声明-el1057e:没有在上下文中注册bean解析器来解析对bean“ipwhitelistingprovider”的访问。

        @Autowired
        IpWhitelistingProvider ipWhitelistingProvider;

        }

        String ip=request.getRemoteAddr();
        if(whitelist.contains(ip)) {

        }
        else {
            return false;
