You need to remove DataSourceAutoConfiguration.class from exclusions. That is what sets up the EntityManagerFactory.
So this:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
// Main class definition
Should be:
#SpringBootApplication()
// Main class definition

Can't find the request for URL's Observer

i'm building my first SOAP application using Spring Boot + Apache CXF and Maven.
I've followed this guide:
https://www.baeldung.com/apache-cxf-with-spring
Without using XML file, so at the end i have those classes:
DemoApplication
#SpringBootApplication
public class DemoApplication{
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
ServiceConfiguration
#Configuration
public class ServiceConfiguration {
#Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
ServletDestinationFactory destinationFactory = new ServletDestinationFactory();
SpringBus bus = new SpringBus();
bus.setExtension(destinationFactory, HttpDestinationFactory.class);
return bus;
}
#Bean
public Endpoint endpoint() {
EndpointImpl endpoint = new EndpointImpl(springBus(), new BaeldungImpl());
endpoint.publish("http://localhost:8080/demo-0.0.1-SNAPSHOT");
return endpoint;
}
}
AppInitializer
public class AppInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext container) {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(ServiceConfiguration.class);
container.addListener(new ContextLoaderListener(context));
ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new CXFServlet());
dispatcher.addMapping("/services/*");
}
}
BaeldungImpl
#WebService(endpointInterface = "com.example.demo.Baeldung")
public class BaeldungImpl implements Baeldung {
private int counter;
#Override
public String hello(String name) {
return "Hello " + name + "!";
}
#Override
public String register(Student student) {
counter++;
return student.getName() + " is registered student number " + counter;
}
#Override
public String ProvaServizio() {
return "";
}
}
Baeldung
#WebService
public interface Baeldung {
public String hello(String name);
public String register(Student student);
public String ProvaServizio();
}
Student
public class Student {
private String name;
Student() {
}
public Student(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
After buildin and deploying on Tomcat, following this URL i reach this:
Available SOAP services:
If i try to go further (adding /hello,/hegister or /ProvaServizio) i've got this error:
No service was found.
And the log says:
15:48:19.416 [http-nio-8080-exec-127] WARN org.apache.cxf.transport.servlet.ServletController - Can't find the request for http://localhost:8080/demo-0.0.1-SNAPSHOT/services/hello's Observer

Failing to autowire a repository field

I'm building a small desktop app using JavaFX and Spring Boot. I used JavaFX Weaver to integrate JavaFX and Spring Boot together.
I want to use the JPA repository Interface to access a MySQL database, however, I get an error when starting the app because of the auto wiring of the repository field.

The package of your class ColorRepository is not defined in component scan.
try to add : #ComponentScan({"package1","package2","..."})

How do I create a database with Spring/Hibernate?

First off: Yes I have searched for previous questions. None of the answers work unfortunately.
I have created an entity class Product, a repository class ProductRepository and a main class Application.
Below you find the code:
Application
#SpringBootApplication
public class Application {
public static void main (String[] args) {
ConfigurableApplicationContext ctx = SpringApplication.run(Application.class, args);
ProductRepository repo = ctx.getBean(ProductRepository.class);
Product product = new Product();
product.setDescription("HDD");
repo.save(product);
}
}
Product
#Entity
#Table(name="Products")
public class Product {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private int product_id;
private String description;
public int getProduct_id() {
return product_id;
}
public void setProduct_id(int product_id) {
this.product_id = product_id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
ProductRepository
#Repository
public interface ProductRepository extends CrudRepository<Product, Integer> {
}
application.properties file
The file looks like this:

Compiling gives zero errors. However, the database does not get created in my localhost. I'm using XAMPP to manage my localhost.
Could somebody provide any help? Many thanks!

<property name="hibernate.hbm2ddl.auto">create</property>
will create tables. But it will not create database. Change the connection url to generate the database as below.
jdbc:mysql://localhost:8080/entmob?createDatabaseIfNotExist=true
Use the below connector in pom.xml and above connection url.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version> <!-- or 5.1.28 / 5.1.30 -->
</dependency>

Here is the solution. As i suggested in the comment section:
I would first try to remove the H2 dependency from the pom.xml and
try . I suspect that your db is embedded.
When springboot finds the h2 dependency it will consider it as an
webapp with embedded db and will ignore your mysql config
