Question

我是JavaFX的新手。我正在尝试在成功登录后加载另一个FXML文件：

<BorderPane id="BorderPane" maxHeight="-Infinity"
  maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity"
  prefHeight="700.0" prefWidth="1370.0" styleClass="anchor_background"
  stylesheets="@index.css" xmlns="javafx.com/javafx/8.0.141"; xmlns:fx="javafx.com/fxml/1";
  fx:controller="properties.Admin_homepageController">

它在这一行显示错误：

Parent admin_homepage = FXMLLoader.load(getClass().getResource("Admin_homepage.fxml"));

错误是：

javafx.fxml.LoadException：文件：/ C：！/Users/Arpit%20Singh/Documents/NetBeansProjects/Properties/dist/run1802424867/Properties.jar /properties/Admin_homepage.fxml在javafx.fxml.FXMLLoader.constructLoadException（ FXMLLoader.java:2601）在javafx.fxml.FXMLLoader.loadImpl（FXMLLoader.java:2543）在javafx.fxml.FXMLLoader.loadImpl（FXMLLoader.java:2441）在javafx.fxml.FXMLLoader.loadImpl（FXMLLoader.java:3214 ）在javafx.fxml.FXMLLoader.loadImpl（FXMLLoader.java:3175）在javafx.fxml.FXMLLoader.loadImpl（FXMLLoader.java:3148）在javafx.fxml.FXMLLoader.loadImpl（FXMLLoader.java:3124）

堆栈跟踪包含：

javafx.fxml.LoadException:
file:/C:/Users/Arpit%20Singh/Documents/NetBeansProjects/Mulani_Properties/dist/run90454756/Mulani_Properties.jar!/mulani_properties/Admin_homepage.fxml

...

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,7]
Message: The processing instruction target matching "[xX][mM][lL]" is not allowed.

现在您应该搜索Message: The processing instruction target matching "[xX][mM][lL]" is not allowed.并找到此问题Error: The processing instruction target matching “[xX][mM][lL]” is not allowed。

原因是您在Admin_homepage.fxml中<?xml version="1.0" encoding="UTF-8"?>之前有其他字符，删除它们并将<?xml version="1.0" encoding="UTF-8"?>放入第一行。
