[Erro ao chamar Stored Procedure, uso spring boot e JPA; Sou iniciante no Java e estou penando muito, alguém pode me ajudar com essa bronca.]

Olá nosso amigo, foram feitas as alterações, porém continua com erro: 

ERROR: public.spesp01() is a procedure
  Dica: To call a procedure, use CALL.

NO Repository
----------------
    @Procedure("public.spesp01")
    void spesp01();

No Service
----------------
    public void executaProcedure(){
          especialidadeRepository.spesp01();
      }

No Controller      
----------------

    @PostMapping("/exeProcedure")
    public void exeProcedure(){
        especialidadeService.executaProcedure();
    }

erro
