[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.
