JPA findAll(spec,Sort)

问题:

I have this code to get all transaction between 2 dates. I would like to get a desc sorted list. What are the possibilities?

@Override public List<Transaction> searchBySubmitDate(final Date startDate,                                              final Date endDate) {     return transactionRepository.findAll(new Specification<Transaction>() {         @Override         public Predicate toPredicate(Root<Transaction> transaction,                                       CriteriaQuery<?> q, CriteriaBuilder cb) {             Predicate between = cb.between(transaction.get(Transaction_.dateSubmit), startDate, endDate);              return between;         }     });

@Override     public List<Transaction> searchBySubmitDate(final Date startDate,                                                  final Date endDate) {         return transactionRepository.findAll(new Specification<Transaction>() {             @Override             public Predicate toPredicate(Root<Transaction> transaction,                                           CriteriaQuery<?> q, CriteriaBuilder cb) {                 Predicate between = cb.between(transaction.get(Transaction_.dateSubmit), startDate, endDate);                  return between;             }         },new Sort(Direction.DESC,"dateSubmit"));

The repository has another method taking a Sort as additional argument. Call this method with an appropriate Sort instance.
