• 记录一下

        String host = serverRequest.uri().getHost();Consumer<HttpHeaders> headersConsumer = consumer -> {consumer.setAccessControlAllowOrigin(host);consumer.setAccessControlAllowCredentials(true);consumer.set("Access-Control-Allow-Headers","*");consumer.set("Access-Control-Allow-Methods", "*");consumer.setAccessControlMaxAge(3600);};ServerResponse.status(HttpStatus.OK).headers(headersConsumer).body(BodyInserters.fromValue(result));

函数式路由匹配，进行响应头的设置。
