[SPRING - JAVA] Errore nel salvataggio usando CrudRepository

[jabjoint]

Buonasera informatici, ho proceduto nel seguente modo:

- Creato un pacchetto tramite initilizr web. assegnando dipendenze: JPA e MySql.
( Riporto di seguito POM.xml )

- Creata classe @Entity User con i relativi get and setter.

- Creata interfaccia IUserRepository

- Uso del metodo/bean CommandLineRunner


(Secondo me manca una dipendenza) riporto pom.xml:

package repository;



import org.springframework.data.repository.CrudRepository;

import org.springframework.stereotype.Repository;



import com.jobmanagements.homemanagement.Entities.User;


@Repository

publicinterface IUserRepository extends CrudRepository<User, Long>{


@Override

default <S extends User> S save(S entity) {
// TODO Auto-generated method stub
returnnull;
}





}

publicstaticvoid main(String[] args) {





        SpringApplication.run(HomeManagementApplication.class, args);




    }

@Bean
    CommandLineRunner commandLineRunner(IUserRepository userRep) {

return args -> {

            User user = new User("Rossi", "Mario", "Url");
                   
                   userRep.save(user);

        };

    }

L'applicativo crea la tabella User ma da questo errore in fase di avvio:

***************************
APPLICATION FAILED TO START
***************************


Description:


Parameter 0 of method commandLineRunner in com.jobmanagements.homemanagement.HomeManagementAp plication required a bean of type 'repository.IUserRepository' that could not be found.




Action:


Consider defining a bean of type 'repository.IUserRepository' in your configuration.


Inoltre io vorrei salvare tramite JButton nel DB ma per il momento son in fase di apprendimento ancora.

In sostanza non viene creato il bean dell' interfaccia? Non dovrebbe essere creato in automatico con spring?

Mi si presentano i seguenti 2 errori prima della compilazione relativamente al pom.xml.

Description Resource Path Location Type
cvc-elt.1.a: Cannot find the declaration of element 'project'. [cvc-elt.1.a] pom.xml /homemanagement line 2 Language Servers
Downloading external resources is disabled. [DownloadResourceDisabled] pom.xml /homemanagement line 3 Language Servers

Nel frattempo ho risolto in parte gli errori aggiornando STS.

Ora non da più alcun errore ma tuttavia NON viene creato il nuovo record utente nella Tabella user.
