javafx.fxml.LoadException：文件路徑錯誤

Question

謝謝大家，問題與文件加載無關，而是與代碼的不同部分有關。 抱歉耽誤您的時間，但還是謝謝您！

我以前在這里看到過這個問題，但是每當我嘗試解決我的問題時，它都不起作用。

嘗試在 java fxml 中加載新窗口時，我使用此方法：

public void openContacts(ActionEvent event) {
    try {
        Parent root = FXMLLoader.load(getClass().getResource("/application/CV.fxml"));
        Scene scene = new Scene(root);
        scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
        Stage stage = new Stage();
        stage.setScene(scene);
        stage.show();
    }
    catch(Exception e) {
        System.out.println(e);
    }
}

但我得到了這個異常：

javafx.fxml.LoadException: 
/C:/Users/tomer/eclipse-workspace/PhoneProj%20V3/bin/application/CV.fxml

有什么幫助嗎？ 謝謝！

有人建議更改項目名稱並刪除空格，沒有做任何事情......我也嘗試提供文件的完整路徑名，而不僅僅是“/application/CV.fxml”。 （完整路徑名是“C:\\Users\\tomer\\eclipse-workspace\\PhoneProjV3\\src\\application\\CV.fxml”）

Answer 1

嘗試刪除項目名稱中的空格。 “PhoneProj V3”得到 urlencoded 導致“PhoneProj%20V3”並且結果名稱不存在。

嘗試將“PhoneProj V3”更改為“PhoneProjV3”（刪除空格）。
