datatable

En el controller agregar un List<Persona>
Crear los métodos set/get

  List<Persona> personaList = new ArrayList<>();

    public List<Persona> getPersonaList() {
        return personaList;
    }

    public void setPersonaList(List<Persona> personaList) {
        this.personaList = personaList;
    }

En el método getPersonaList editarlo e invocar el metodo findAll() del Repository

 return personaRepository.findAll();

Quedaría

 public List<Persona> getPersonaList() {
//        return personaList;
        return personaRepository.findAll();
    }
