我正在尝试为我的pom添加Spring，但我想知道我的构建是否看起来像这样。有人可以帮我如何与java fx进行Spring集成吗？
我的pom:

主要类：
public class App extends Application {
private static Scene scene;
@Override
public void start(Stage stage) throws IOException {
scene = new Scene(loadFXML("primary"));
stage.setScene(scene);
stage.show();
}
static void setRoot(String fxml) throws IOException {
scene.setRoot(loadFXML(fxml));
}
private static Parent loadFXML(String fxml) throws IOException {
FXMLLoader fxmlLoader = new FXMLLoader(App.class.getResource(fxml + ".fxml"));
return fxmlLoader.load();
}
public static void main(String[] args) {
launch();
} }
我搜索了一下，没有找到任何关于将javafx与Spring集成的信息，有人能帮我如何集成Spring吗？
我试着用我在摇摆项目中使用的东西，但没有成功。
你的主app要像这样维护Spring的应用上下文。
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;
@Configuration // or @SpringBootApplication if you used spring boot.
public class App extends Application {
private static Scene scene;
private AbstractApplicationContext context;
@Override
public void init() throws Exception {
this.context = new AnnotationConfigApplicationContext(App.class);
super.init();
}
@Override
public void start(Stage stage) throws IOException {
SpringFxmlLoader loader = new SpringFxmlLoader(this.context);
Parent root = loader.loadFromResource("primary.fxml");
stage.setScene(new Scene(root));
stage.show();
}
public static void main(String[] args) {
launch();
}
}
使用 SpringFxmlLoader 将控制器作为 Spring Bean 返回。
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import org.springframework.context.ApplicationContext;
import javafx.fxml.FXMLLoader;
public class SpringFxmlLoader extends FXMLLoader {
private ApplicationContext context;
protected SpringFxmlLoader() {
}
public SpringFxmlLoader(ApplicationContext context) {
this.context = context;
setControllerFactory(context::getBean); // return a spring bean from spring's application context.
}
public ApplicationContext getContext() {
return this.context;
}
public <T> T loadFromResource(String resource) throws IOException {
return loadFromResource(resource, null);
}
public <T> T loadFromResource(String resource, Class<?> root) throws IOException {
URL resourceURL = context.getResource(resource).getURL();
setLocation(resourceURL);
if(root != null) setRoot(root);
try (InputStream fxml = resourceURL.openStream()) {
return load(fxml);
}
}
}
您的控制器应该像这样看起来像一个Spring豆。
@Controller
@Scope("prototype")
public class PrimaryController {
@FXML private Parent rootView;
@FXML private TitledPane settingPane;
@Autowired private SomeBean someBean; // now you can autowire spring beans.
// braa....
}
不要忘记在primary.fxml中使用fx:controller属性指定控制器类。
