无法自动连接存储库字段

Question

我正在使用JavaFX和Spring Boot构建一个小型桌面应用程序。我使用 JavaFX Weaver 将 JavaFX 和 Spring Boot 集成在一起。

我想使用 JPA 存储库界面访问 MySQL 数据库，但是，由于存储库字段的自动连接，我在启动应用程序时出现错误。

控制台错误

项目结构

服务

@Service
public class ColorService {
// I get the error when I add these 2 lines of code
@Autowired
private ColorRepository colorRepository;
public List<Color> getColors(){
return colorRepository.findAll();
}
}

存储 库

@Repository
public interface ColorRepository extends JpaRepository<Color, Integer> {
}

实体

@Entity
@Table(name="color")
public class Color {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name="color_id")
private int id;
@Column
private String colorName;
public Color() {
}
public Color(String colorName) {
this.colorName = colorName;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getColorName() {
return colorName;
}
public void setColorName(String colorName) {
this.colorName = colorName;
}
}

主应用

@SpringBootApplication
public class MainApp {
public static void main(String[] args) {
Application.launch(JavaFxApplication.class, args);
}
}

JavaFX 主应用程序

public class JavaFxApplication extends Application {
private ConfigurableApplicationContext applicationContext;
@Override
public void init() {
String[] args = getParameters().getRaw().toArray(new String[0]);
this.applicationContext = new SpringApplicationBuilder().sources(MainApp.class).run(args);
}
@Override
public void start(Stage stage) {
FxWeaver fxWeaver = applicationContext.getBean(FxWeaver.class);
Parent root = fxWeaver.loadView(MainController.class);
Scene scene = new Scene(root);
scene.getStylesheets().add("css/style.css");
stage.setScene(scene);
stage.show();
}
@Override
public void stop() {
this.applicationContext.close();
Platform.exit();
}
}

类 ColorRepository 的包未在组件扫描中定义。

尝试添加：@ComponentScan({"包1"，"包2"，"..."}(
