I am wondering is it possible to configure SpringDataJpa to be used in javaSE, without spring boot.
I have seen some examples with xml configurations, for spring framework 4, but sadly i did not manage to make them work with spring framework 5. And would it be possible to do that with properties configuration instead of .xml configurations.
When i tryed to use what @majid suggested, i get following error
Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [App]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/web/servlet/config/annotation/WebMvcConfigurer.class] cannot be opened because it does not exist

Yesterday however i had some time to play and i managed to make something like this work.

I would just love not to use xml, so i need non xml alternative to those settings. Here is my pom.

can you share your code; my hunch is you might be missing EnableJpaRepositories annotation.
Here is a quick sample:
App.java
@Configuration
@ComponentScan
@EnableJpaRepositories
public class App {
public static void main(String[] args) {
ApplicationContext ctx = new AnnotationConfigApplicationContext(App.class);
PersonService service = ctx.getBean(PersonService.class);
Person p = new Person("Raphael");
service.savePerson(p);
}
@Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).build();
}
@Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setPackagesToScan("com.demo.spring");
factory.setDataSource(dataSource());
factory.afterPropertiesSet();
return factory.getObject();
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory());
return txManager;
}
}
PersonRepo.java
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
public interface PersonRepo extends JpaRepository<Person, Long> { }
PersonService.java
@Service
public class PersonService {
@Autowired
private final PersonRepo personRepo;
public PersonService(PersonRepo personRepo) {
this.personRepo = personRepo;
}
public Person savePerson(Person p){
return personRepo.save(p);
}
}
