谢谢大家，问题与文件加载无关，而是与代码的不同部分有关。很抱歉浪费您的时间，但是还是谢谢您！

我以前在这里已经看到过这个问题，但是每当我尝试解决我的问题时，它就不会起作用。

当尝试在java fxml中加载新窗口时，我使用以下方法：

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);
    }
}

但是我很高兴：

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

有帮助吗？谢谢！

有人建议更改项目名称并删除空格，什么也没做... 我还尝试提供文件的完整路径名，而不只是给出“ /application/CV.fxml”。 （完整路径名称为“ C：\ Users \ tomer \ eclipse-workspace \ PhoneProjV3 \ src \ application \ CV.fxml”）

1 个答案:

答案 0 :(得分：-1)

尝试删除项目名称中的空格。对“ PhoneProj V3”进行urlencode编码，结果为“ PhoneProj％20V3”，并且该结果名称不存在。

尝试将“ PhoneProj V3”更改为“ PhoneProjV3”（删除空格）。
