spring cloud gateWay 404

gateWay网关负载均衡报404错误，我的yml文件配置

lxyyf-ucenter 负载到这个服务时，404错误，通过debug源码（注意logback的日志级别调为debug级别，请求的实际地址打印不出来）。日志打印的请求信息，url被截取了两次，StripPrefix=1 自带的过滤器会根据/截取一次，我自定义的RequestGlobalFilter过滤器又截取了一次，

public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
       // 1. 清洗请求头中from 参数
       ServerHttpRequest request = exchange.getRequest().mutate()
           .headers(httpHeaders -> httpHeaders.remove(SecurityConstants.FROM))
           .build();

       // 2. 重写StripPrefix,默认截取一次，截取第一段，配置文件中无需再配置 StripPrefix=1 不然会截取两次
       addOriginalRequestUrl(exchange, request.getURI());
       String rawPath = request.getURI().getRawPath();
       log.info("rawPath:{}",rawPath);
       String newPath = "/" + Arrays.stream(StringUtils.tokenizeToStringArray(rawPath, "/"))
           .skip(1L).collect(Collectors.joining("/"));
       log.info("newPath:{}",newPath);
       ServerHttpRequest newRequest = request.mutate()
           .path(newPath)
           .build();
       exchange.getAttributes().put(GATEWAY_REQUEST_URL_ATTR, newRequest.getURI());

       return chain.filter(exchange.mutate()
           .request(newRequest.mutate()
               .build()).build());
   }

请求的源路径：http://localhost:9999/ucenter/useCenter/hello到底层变为http://localhost:4009/hello了，所以报404错误

整合Security,忽略一些url
