我在尝试使用 javafx 和 spring 调试项目时遇到问题
我的pom. xml

我的主要:
@Override public void start(Stage primaryStage) throws Exception { // TODO Auto-generated method stub context = SpringApplication.run(JavafxApplication.class); FXMLLoader loader = new FXMLLoader(JavafxApplication.class.getResource("/Home.fxml")); loader.setControllerFactory(context::getBean); Scene scene = new Scene(loader.load()); primaryStage.setScene(scene); primaryStage.show(); }
尝试使用 maven 编译时出现以下错误:
[INFO] Scanning for projects...

我去运行配置并进行此操作:
最佳答案
您发布的 pom 缺少 javafx-maven-plugin
。如此处记录的:https://openjfx.io/openjfx-docs/#IDE-Eclipse (Maven 部分),您需要包含它以处理 JavaFX 依赖项(将它们包含在模块路径中,添加所需的模块),同时将其余依赖项保留在类路径中(如果您的项目是非模块化的) )。
如果您想运行目标 javafx:run
,如图所示,您确实需要定义此目标的插件。
这对我有用(JavaFX + Spring):
POM

主类
package org.openjfx;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
@SpringBootApplication
public class MainApp extends Application {
private ConfigurableApplicationContext springContext;
private FXMLLoader fxmlLoader;
@Override
public void init() throws Exception {
springContext = SpringApplication.run(MainApp.class);
fxmlLoader = new FXMLLoader();
fxmlLoader.setControllerFactory(springContext::getBean);
}
@Override
public void start(Stage stage) throws Exception {
fxmlLoader.setLocation(getClass().getResource("scene.fxml"));
Parent root = fxmlLoader.load();
Scene scene = new Scene(root);
scene.getStylesheets().add(getClass().getResource("styles.css").toExternalForm());
stage.setTitle("JavaFX and Maven");
stage.setScene(scene);
stage.show();
}
@Override
public void stop() {
springContext.stop();
}
public static void main(String[] args) {
launch(args);
}
}
FXMLController
package org.openjfx;
import org.springframework.stereotype.Controller;
@Controller
public class FXMLController {
public void initialize() {
// TODO
}
}
现在您可以从控制台运行:
mvn clean javafx:run
或添加一个目标到运行配置 -> Maven Build
:clean javafx:run
。
您应该看到 JavaFX 应用程序正在运行,并且 Spring 输出:
