프로그램을 실행하는 동안 JavaFX에 FXML 코드가 혼동하는 오류가 있습니다. 이름
먼저 하나 :
javaFx에서 TARGETINVOCATIONEXCEPTION을 (를) 풀려면 어떻게해야합니까?
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafxapplication5.FXMLDocumentController ?>
<GridPane fx:controller = "FXMLDocumentController" hgap="10.0" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="100.0" prefWidth="600.0" vgap="10.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">

<children>
<Label text="Choose gender:" />
<RadioButton mnemonicParsing="false" text="Female" GridPane.rowIndex="2">
<toggleGroup>
<ToggleGroup fx:id="gender" />
</toggleGroup>
</RadioButton>
<RadioButton mnemonicParsing="false" selected="true" text="Male" toggleGroup="$gender" GridPane.rowIndex="1" />
<Button mnemonicParsing="false" onAction="" onMouseClicked="#BClickedActionHandler" text="OK" GridPane.rowIndex="4" />
</children>
<padding>
<Insets bottom="10.0" left="10.0" right="10.0" top="10.0" />
</padding>
</GridPane>
두 번째 파일 이름은 다음과 같습니다 : 포함 FXMLDocumentController.java : 다음 코드가 포함 F2XML.fxml
나는 세 개의 파일이
package javafxapplication5;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.RadioButton;
public class FXMLDocumentController implements Initializable {
@FXML
RadioButton Male;
@FXML
RadioButton Female;
@FXML
Button OK;
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
@FXML
public void BClickedActionHandler() {
System.out.println("Hello");
}
}
그리고 세번째 것은 : JavaFXApplication5.java 이는 포함이 오류를 해결

수있는 사람의 도움 :
