无法使用Spring和JavaFX确定数据库类型为NONE Exception的嵌入式数据库驱动程序类

Question

我想使用Spring的自动配置功能来连接和创建数据源。

我在IntelliJ上使用JavaFX，Spring和Maven。我首先运行'mvn install'然后运行jar文件。但是，即使我相信我已按照正确的步骤操作，我也会收到以下错误：

Caused by: org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

我在src / main / resources下的application.properties文件中定义了我的数据源属性：

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/project_name?autoReconnect=true&useSSL=false
spring.datasource.username=root
spring.datasource.password=password

spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.jpa.properties.hibernate.globally_quoted_identifiers=true
spring.jpa.show-sql=true

启动该程序的我的主要课程是：

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan
public class Main extends Application {

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = SpringFXMLLoader.load(getClass().getResource("/welcome.fxml"), ResourceBundle.getBundle("language", new Locale("en")));
        stage.setTitle("Softserver");
        stage.setScene(new Scene(root));
        stage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

我的自定义SpringFXMLLoader类：

public class SpringFXMLLoader {

    private static final ApplicationContext context = new AnnotationConfigApplicationContext("package_name");

    public static <T> T load(URL url, ResourceBundle languageProperties) {
        try {
            FXMLLoader loader = new FXMLLoader(url, languageProperties);
            loader.setControllerFactory(context::getBean);
            return loader.load();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
}

我还缺少什么？非常感谢任何帮助！
