NoteRepository Interface:

package com.example.easynotes.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import com.example.easynotes.model.Note;
import org.springframework.stereotype.Repository;

@Repository
public interface NoteRepository extends JpaRepository<Note,Long> {

}

Answer 1

1. Mark Your NoteRepository class with @Repository annotation.
2. And mark your main class with @EnableJpaRepositories(basePackages = {"com.example.easynotes.repository"})
