AutoCompletionBinding无法访问类com.sun.javafx.event.EventHandlerManager

我对

javafx

和

org.controlsfx.control.textfield.TextFields

有一些问题。我正在尝试实现一个功能，从数据库中获取可能的用户输入预测，这样用户只能选择“授权”选项。在使用

controlsfx

时，我遇到了这个错误

错误：

Exception in thread "JavaFX Application Thread" java.lang.IllegalAccessError: class org.controlsfx.control.textfield.AutoCompletionBinding (in unnamed module @0x239a4ba) cannot access class com.sun.javafx.event.EventHandlerManager (in module javafx.base) because module javafx.base does not export com.sun.javafx.event to unnamed module @0x239a4ba

有人能给我一些如何实现此功能的示例，或者告诉我我做错了什么吗？

如果您使用的是ControlsFX 11，请在运行时命令行中添加以下VM选项：

--add-exports javafx.base/com.sun.javafx.event=org.controlsfx.controls

注：之前的答案（在其他网站上，也在这里）建议如下：

--add-exports javafx.base/com.sun.javafx.event=ALL-UNNAMED

---

但是，ControlFX的最新版本似乎是模块化的，并且这些模块不再是未命名的。如果您使用的是以前的版本（例如，版本9），请使用命令行选项的所有未命名变体。

如果您在这里结束并使用maven插件（

javafx:run

）运行您的应用程序，您可以使用以下配置使其运行

        <plugin>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <version>0.0.4</version>
            <configuration>
                <mainClass>some.package.App</mainClass>
                 <options>
                    <option>--add-exports</option>
                    <option>javafx.base/com.sun.javafx.event=org.controlsfx.controls</option>
                 </options>
            </configuration>
        </plugin>

org.openjfx
javafxmaven插件
0.0.4
some.package.App
--添加导出
javafx.base/com.sun.javafx.event=org.controlsfx.controls

使用正确版本的ControlsFX（9）。我正在使用

org.ControlsFX:ControlsFX:9.0.0

我找到了一个解决方案！我必须向VM选项中添加

——addexports=javafx.base/com.sun.javafx.event=ALL-UNNAMED

。

        <plugin>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-maven-plugin</artifactId>
            <version>0.0.4</version>
            <configuration>
                <mainClass>some.package.App</mainClass>
                 <options>
                    <option>--add-exports</option>
                    <option>javafx.base/com.sun.javafx.event=org.controlsfx.controls</option>
                 </options>
            </configuration>
        </plugin>
