无法使用 Spark Java 框架提供静态网页

问：

我有以下代码 - 它被配置为在包（src/main/resources/public）中提供静态网页

这不起作用，我在日志中也没有看到任何异常

 public void startRestServer() {
        try {
            port(serverPort);
//            staticFiles.location(System.getProperty("user.dir") + "/src/main/resources/public/");
            staticFiles.location("/public");
            connectionPool = SQLiteConnectionPool.getInstance(fileServerLocation, MIN_THREADS, MAX_THREADS, TIMEOUT);
            staticFiles.externalLocation(this.fileServerLocation);
            init();
            awaitInitialization();
            loadRestApiServices();
            LOGGER.debug(String.format("REST services started :: http://%s:%s%s/",
                    InetAddress.getLocalHost().getHostAddress(), serverPort, uriPath));
        } catch (Exception e) {
            LOGGER.error("REST services failed to start", e);
        }
    }

我在下面配置了 API 路径

public void loadRestApiServices() {
        UploadService uploadService = new UploadServiceImpl();
        path(RestController.uriPath, () -> {
            before("/*", (req, res) -> LOGGER.info("Received api call"));

            get("/greet", (req, res) -> {
                return "Hello Work !";
            });

            post("/upload", (req, res) -> {
                JSONObject jsonObject = new JSONObject(req.body());
                uploadService.uploadCustomPlugin(jsonObject);
                return null;
            });

            after((req, res) -> res.header("Content-Encoding", "gzip"));

        });

预期结果：

我希望它向用户提供索引 .html - 这基本上是一个帖子表单，用于上传文件
