这是我第一次在Spring Boot中使用Javafx 运行我的应用程序时出现以下错误
@GetMapping
public ResponseEntity<dataTableDTO> getProject(HttpServletRequest request, @RequestParam(name="draw") int draw) throws Exception {...}
主要阶级
Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.0.RELEASE:run (default-cli) on project basic: Could not exec java: Application finished with exit code: 1 -> [Help 1]
}
控制器类
@SpringBootApplication
public class BasicApplication extends Application {
private Parent root;
private ConfigurableApplicationContext context;
@Override
public void init() throws Exception {
context = SpringApplication.run(BasicApplication.class);
FXMLLoader loader=new FXMLLoader(getClass().getResource("/fxml/Scene.fxml"));
loader.setControllerFactory(context::getBean);
root=loader.load();
}
@Override
public void start(Stage primaryStage) throws Exception {
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
}
@Override
public void stop() throws Exception {
context.close();
}
public static void main(String[] args) {
launch(BasicApplication.class,args);
}
}
pom.xml
public class SceneController implements Initializable {
@FXML
private Label label;
@FXML
private void buttonAction(){
label.setText("Hello World!");
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
http://maven.apache.org/xsd/maven-4.0.0.xsd“> 4.0.0
<?xml version="1.0" encoding="UTF-8"?>
请问发生了什么。 为什么org.springframework.boot:spring-boot-maven-plugin:2.0.0.RELEASE:run无法执行?

使用NetBeans IDE运行应用程序

好了,知道为什么会发生错误。我没有在控制器类中包含@Component
。我的错误。
@Component
public class SceneController implements Initializable {
@FXML
private Label label;
@FXML
private void buttonAction(){
label.setText("Hello World!");
}
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}
`现在一切正常

我注意到您尚未显示Scene.fxml文件(用于指定应用程序布局的文件)或项目的目录结构。
检查/ src / main / resources / fxml /目录中是否具有Scene.fxml文件。
我已经运行了您的代码,包括在我的计算机中使用https://start.spring.io/创建基础项目,并将其用作Scene.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane xmlns="http://javafx.com/javafx">
<Label text="Main Content"/>
</AnchorPane>
并运行命令 mvn clean spring-boot:run ,它可以正常工作。
检查是否正确配置了JAVA_HOME环境变量。

希望这会有所帮助。
