Map<String, String> routes = getDynamicRouteFromNacos();
return builder.routes()
.route("dynamic_route", r -> r.path("/dynamic")

// 示例方法，实际应从Nacos配置中心获取路由配置
private Map<String, String> getDynamicRouteFromNacos() {
Map<String, String> routes = new HashMap<>();

}
}这个代码示例展示了如何在Spring Cloud Gateway中配置静态和动态路由，静态路由是直接在配置中指定的，而动态路由则是通过从Nacos配置中心获取的。在实际应用中，需要替换getDynamicRouteFromNacos()方法，从Nacos配置中心实时获取路由配置。
