Spring can't find the specified Bean

Question

I have a Spring aplication that uses the JpaRepository to connect to h2, but it's giving the following error:

Field usuarioRepository in com.julio.demo.DemoApplication required a bean of type 'com.julio.repositories.UsuarioRepository' that could not be found.

The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true) Action:

Consider defining a bean of type 'com.julio.repositories.UsuarioRepository' in your configuration.

I tried this solution and think I have already added this bean in the configuration. Is my @Repository configured correctly? My configuration can be found below:

package com.julio.demo;

import java.util.Arrays;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import com.julio.domain.Usuario;
import com.julio.repositories.UsuarioRepository;

@EnableJpaRepositories
@SpringBootApplication
public class DemoApplication implements CommandLineRunner {

    @Autowired
    private UsuarioRepository usuarioRepository;

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        Usuario u1 = new Usuario(null, "julio", "julio", "123");
        Usuario u2 = new Usuario(null, "cesar", "cesar", "123");

        usuarioRepository.saveAll(Arrays.asList(u1,u2));
    
    }

}

package com.julio.repositories;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.julio.domain.Usuario;

@Repository
public interface UsuarioRepository extends JpaRepository<Usuario, Integer>{

}

application properties:

spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
spring.datasource.url=jdbc:h2:file:~/test
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create
spring.jpa.properties.hibernate.format_sql=true

here are my dependencies if that helps:

@julinoo You may have to define the basePackage. since the package name is not a standard one, as follows:

@EnableJpaRepositories(basePackages = {"com.julio.repositories"})
