cartaoController 빈은 어디에 있습니까? 그리고 그것이 무엇을 위해 봉사합니까? –

'PagingAndSorting'Repository' 또는'JpaRepository'를 확장하고 인터페이스에서 모든 메소드를 제거하십시오. 그것들은 모두 당신을 위해 제공 될 것입니다. –

을 병합하여 실제로 다른 방법으로 그것을 할 수 있습니다. CartaoRepository에 대해서만 extend CrudRepository입니다. 가 옆 구현이 save 방법이 있습니다

@Transactional 
    public <S extends T> S save(S entity) { 

     if (entityInformation.isNew(entity)) { 
      em.persist(entity); 
      return entity; 
     } else { 
      return em.merge(entity); 
     } 
    }

그래서 당신의 실체를 병합하면 isNew 메소드를 오버라이드 (override)하고 이에 대한 당신은 할 수 extend AbstractPersistable 모델에 대한.
