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

Question

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，该功能可以从数据库中获取可能的用户输入预测，以便用户只能选择“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

我了解到，引用由于 Java Web Start 不再是 Java SE 11 及更高版本的一部分，因此我们不会对此进行研究。。不知道是因为这个还是我做错了什么。

这是我的代码:

    package sample;
/**
 * Sample Skeleton for 'sample.fxml' Controller Class
 */

import java.net.URL;
import java.util.*;

import javafx.fxml.FXML;
import javafx.scene.control.TextField;
import org.controlsfx.control.textfield.TextFields;

public class Controller{

    @FXML // ResourceBundle that was given to the FXMLLoader
    private ResourceBundle resources;

    @FXML // URL location of the FXML file that was given to the FXMLLoader
    private URL location;

    // fx:id="inputAutoComplete";
    @FXML
    private TextField inputAutoComplete;

    @FXML // This method is called by the FXMLLoader when initialization is complete
    void initialize() {
        System.out.println("XD");
        listenKey();
    }

    ArrayList<String> possibleWordSet = new ArrayList<>();

    public void listenKey(){
        databaseConnection dbconn = new databaseConnection();
        inputAutoComplete.setOnKeyPressed((event) -> {
            if(inputAutoComplete.getText().length() > 4){
                System.out.println(inputAutoComplete.getText());
                possibleWordSet = dbconn.getSuggestedData(inputAutoComplete.getText());
                System.out.println(possibleWordSet);
                TextFields.bindAutoCompletion(inputAutoComplete,possibleWordSet);
            }
        });
    }
}

有人可以给我一些如何实现此功能的示例，或者只是告诉我我做错了什么吗？

如果您使用的是 ControlsFX 11，请将以下 VM 选项添加到运行时命令行:

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

注意:之前的答案(在其他网站上以及此处的 SO)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 ALL-UNNAMED 变体。
