@FXML注释和FXMLLoader类未解析为Java 11和JavaFX 11中的类型 [英] @FXML annotation and FXMLLoader class not resolved to a type in Java 11 and JavaFX 11

问题描述

之前我的项目曾经是Java 8，但现在我正在使用Java 11和JavaFX 11，现在JavaFX已经从Java 11开始与Java解耦了。我没有下载JavaFX SDK，但在pom中添加了以下依赖项。 xml用于获取在早期版本中曾经是Java本身一部分的必需模块和jar文件。

Earlier my project used to be on Java 8 but now I am using Java 11 along with JavaFX 11 and now JavaFX has been decoupled from Java since Java 11. I haven't download the JavaFX SDK but added below dependency in pom.xml for getting required modules and jar files which were used to be part of Java itself in earlier versions.

       <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
            <version>11</version>
        </dependency>

但我收到编译错误无法解析为类型 on @FXML annotation和 FXMLLoader class。

But I am getting compilation error can not be resolved to a type on @FXML annotation and FXMLLoader class.

我是否需要添加一些其他/额外的依赖项来解决此问题？

Do I need to add some other/extra dependencies to resolve this issue?

推荐答案

FXML（ @FXML 注释，FXMLLoader ...）被移植到带有Java 9版本的模块 javafx.fxml 。

FXML (@FXMLannotation, FXMLLoader...) were moved to the module javafx.fxml with the Java 9 release.

在JavaFX 11之前，无论何时调用与JavaFX相关的内容，您都可以在SDK中使用所有javafx模块。

Before JavaFX 11, whenever you were calling something JavaFX related, you had all the javafx modules available within the SDK.

但是现在你必须包括你需要的那些：

But now you have to include the ones you need:

<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-controls</artifactId>
    <version>11</version>
</dependency>
<dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-fxml</artifactId>
    <version>11</version>
</dependency>

请注意 javafx.controls 取决于 javafx.graphics 和 java.base ，因此您不需要包含这些内容。并且 javafx.fxml 直接取决于 javafx.base 。

Note that javafx.controls depends on javafx.graphics and java.base, so you don't need to include those. And javafx.fxml directly depends on javafx.base.
