Describe what happened (or what feature you want)

1、我在dashboard上保存流控规则后持久化后至nacos

2、gateway 监听nacos规则发生变化后
GatewayRuleManager.loadRules 去加载了规则，但是访问资源时规制并没有生效

case GATEWAY_API:
                GatewayApiDefinitionManager.loadApiDefinitions(sentinelGatewayApiParser.convert(sentinelStrategyRule));
                break;
            case GATEWAY_FLOW:
                GatewayRuleManager.loadRules(sentinelGatewayFlowRuleParser.convert(sentinelStrategyRule));
                break;

结果限流并不生效，请问如何解决

SentinelGatewayFilter routeId 会自动加上前缀，访问API时直接报404

API gateway 默认统计维度都是 route 维度，可以按照簇点链路页面里面的 route 名称来配置，或自定义 API 分组来自定义统计维度。

哥们我就是这样配置的。但是实际是不生效的哈
GatewayFlowSlot ->checkGatewayParamFlow -> GatewayRuleManager.getConvertedParamRules

SentinelGatewayFilter -> 结果 routeId 变了。。。然后再到 getRulesForResource 时就直接拿不到配置了。。。

你这个配置明显不是 route 的配置。根据簇点链路页面显示的资源名来配置，或自定义 API 分组。

URL 资源名不应该出现在这里。确保下 SCA 版本用的最新版本，并且 application.properties 里面 spring.cloud.sentinel.filter.enabled 配置项置为 false

SentinelGatewayFilter 里对api分组的

Set<String> matchingApis = pickMatchingApiDefinitions(exchange);
        for (String apiName : matchingApis) {
            Object[] params = paramParser.parseParameterFor(apiName, exchange,
                r -> r.getResourceMode() == SentinelGatewayConstants.RESOURCE_MODE_CUSTOM_API_NAME);
            asyncResult = asyncResult.transform(
                new SentinelReactorTransformer<>(new EntryConfig(apiName, ResourceTypeConstants.COMMON_API_GATEWAY,
                    EntryType.IN, 1, params))
            );
        }
//这个地方一直显示没有匹配上的。。。没明白我路径按精确配置的。咋还匹配不上呢
 Set<String> pickMatchingApiDefinitions(ServerWebExchange exchange) {
        return GatewayApiMatcherManager.getApiMatcherMap().values()
            .stream()
            .filter(m -> m.test(exchange))
            .map(WebExchangeApiMatcher::getApiName)
            .collect(Collectors.toSet());
    }
