AjFmO :

I'm really new into Spring, specifically Spring Boot. Please I beg you, be the most explicit possible, give me docs to read so I can understand very well what I have to do.

My project is using MySQL+JavaFX+Spring Boot+Spring Data JPA+Hibernate frameworks/technologies.

This is my POM file.

This is my .properties configuration.

spring.main.banner-mode=off

logging.level.org.hibernate.SQL=debug
#logging.level.org.hibernate.type.descriptor.sql=trace
logging.level.=error

This is my main class

@SpringBootApplication(scanBasePackages = { "com.nubeclick.pos" })
public class MainApp extends Application {

private static final Logger log = LoggerFactory.getLogger(MainApp.class);

public static void main(String[] args) throws Exception {

    SpringApplication.run(MainApp.class, args);
    // launch(args);
}

@Override
public void start(Stage stage) throws Exception {
    try {
        log.info("Starting Hello JavaFX and Maven demonstration application");

        String fxmlFile = "/fxml/Main.fxml";
        log.debug("Loading FXML for main view from: {}", fxmlFile);
        FXMLLoader loader = new FXMLLoader();
    Parent rootNode = (Parent) loader.load(getClass().getResourceAsStream(fxmlFile));

        log.debug("Showing JFX scene");
        Scene scene = new Scene(rootNode);
        scene.getStylesheets().add("/styles/styles.css");
        stage.setTitle("NubeClick - Point of Sales");
        stage.setScene(scene);
        stage.show();
    } catch (Exception e) {
    // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

This is the stacktrace:

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Failed to determine a suitable driver class

The Spring message is this:

Description:

Failed to auto-configure a DataSource: 'spring.datasource.url' is not specified and no embedded datasource could be auto-configured.

Reason: Failed to determine a suitable driver class

Action:

Consider the following: If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.

If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

I have refered to this other post and this other one

I don't know what else to do, maybe start all over again from zero but I want to adapt those frameworks to my current project.

What can I do to solve this?

Edit

Crazy thing, I decided to upload the project to another repository, did a whole clean to the project folder (deleted .project, .settings, .classpath, bin, target) and reimported project into eclipse, did configure -> add maven nature, and now the error is gone, at least this error, got some other errors but now it loads everything from the properties file, so, Why did this happened?
