clojure.java.io/resource返回nil

我需要在Clojure中加载基于fxml的JavaFX场景, 但是当我尝试加载资源“view.fxml”时,它返回nil。

这是我现在的代码:

(ns ui.ui_controller
(:import (javafx.application Application)
       (javafx.fxml FXMLLoader)
       (javafx.scene Scene)
       (javafx.stage Stage)))

(gen-class
:name ui.ui_controller
:extends javafx.application.Application)

(defn -main [& args]
(Application/launch ui.ui_controller args))

(defn -start [this stage]

 (let [loc (clojure.java.io/resource "view.fxml") 
    root (FXMLLoader/load loc)]

(.setScene stage (Scene. root))
(.setTitle stage "JavaFXML with Clojure Example")
(.show stage)))

在resources文件夹中是view.fxml文件,应加载该文件。

在通话中(println(clojure.java.io/resource“view.fxml”))它会返回nil ...

知道这里出了什么问题吗?

谢谢!

这是一个例子

(ns tst.clj.core
  (:use clj.core
        clojure.test )
  (:require
    [clojure.java.io :as io]
  ))

(def words (slurp (io/file (io/resource "count.txt"))))
(println words)

> cat resources/count.txt
one
two
three

> lein test

one
two
three
