网关路由使用lb://无法调用微服务，改http正常

我有个网关路由相关的问题，路由配置使用 lb://auth-center 这种就调不过去，改为 http://localhost:8081就正常。其他微服务也是这种情况。使用的是gateway网关，路由配置如下： /** * 配置路由规则 * 集成限流配置到不同的API路由 */ @Bean public RouteLocator customRouteLocator(RouteLocatorBuilder builder) { logger.info("Configuring custom route locator with rate limiting");

    RouteLocator routeLocator = builder.routes()
            // 认证中心路由 - 使用严格限流
            .route("auth-center", r -> r
                    .path("/api/auth-center/**")
                    .filters(f -> f
                            .stripPrefix(2)
                            .requestRateLimiter(c -> c
                                    .setRateLimiter(strictRateLimiter)
                                    .setKeyResolver(ipKeyResolver)
                                    .setDenyEmptyKey(false)
                            )
                            .circuitBreaker(c -> c.setName("authCenterCircuitBreaker").setFallbackUri("forward:/auth-fallback"))
                    )

// .uri("lb://auth-center") .uri("http://localhost:8081")
