我通过使用spring数据的日期恢复对象时遇到问题问题是对象返回为null,尽管此对象不为null 谢谢你的回复 亲切
@Repository
public interface ProspectStatistiqueRepository extends JpaRepository<ProspectStatique, Long> {
@Query("select p from ProspectStatique p where p.date_consultation =:date_consultation")
public ProspectStatique getProspectCountByDate(@Param("date_consultation") Date date_consultation);
}
@Autowired
ProspectStatistiqueRepository prospectStatistiqueRepository;
@GetMapping("/products")
public ProductStatique findProductNumberBydate(@RequestParam String date) throws CustomerException, ParseException {
DateFormat format = new SimpleDateFormat("MMMM d, yyyy 'at' hh:mm a", Locale.ENGLISH);
Date dateConvert = format.parse(date);
System.out.println("date param " + date);
System.out.println("dateConvert variable" + dateConvert);
ProductStatique pp = productStatiqueService.getProductCount(dateConvert);
return pp;
}
答案 0 :(得分:1)
您使用 JpaRepository ,因此您可以使用“Between”,“After”和“Before”来处理日期:
@Repository
public interface ProspectStatistiqueRepository extends JpaRepository<ProspectStatique, Long> {
//1-Between
public List<ProspectStatique> findByDate_consultationBetween(Date date1,Date date2);
//2-After
public List<ProspectStatique> findByDate_consultationAfter(Date date);
//3-Befor
public List<ProspectStatique> findByDate_consultationBefore(Date date);
}
