Hi,

Can you verify that you have @Repository annotation on the NoteRepository interface?

[Dhursh]

Yeah... i have the annotation.. please find the below code snippet of my NoteRepository interface

package com.example.easynotes.repository;

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

import com.example.easynotes.model.Note;

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

}

Repository Annotation should be first letter uppercase.

You probably need to make sure your Repository gets scanned.

Since i created my Repository and Entity classes in a different package, i had to use the following two Annotations on the Main App class to make the classes scanned properly:

@EnableJpaRepositories(basePackages = {"mypkg"})

@EntityScan(basePackages = {"mypkg"})

Hi @arun-ammasai , @dtsw , @Dhursh ,

If you still interested about the repo, I just create a PR to solve all the problems and upgrade jdk & spring boot.
