我的ConfigMap如下图所示：最后一米：

我的Spring Boot 2 Controller看起来像这样：
@GetMapping(path = "/kukus")
public Mono<List> getLabels(@RequestParam Long assetId, @RequestParam Long useCaseId,
@RequestParam Long fileId) {
log.info("About to get labels with fileId={} for asset={} for usecase={}", fileId, assetId, useCaseId);
return labelServiceClient.getLabels(assetId, useCaseId, fileId);
}
当我从基本部署中的Kubernetes运行它时，出现错误。看起来configMaps无法处理URL中的"%d"。你能帮忙吗？
