現在我想通過查詢更新實體來更改數據庫中的一些數據，但我得到這個錯誤：無法提取的ResultSet
HTTP Status 500 - Request processing failed; nested exception is
org.springframework.orm.jpa.JpaSystemException: could not extract ResultSet; nested exception is
org.hibernate.exception.GenericJDBCException: could not extract ResultSet
這是我的映射控制器：
@RequestMapping(value="/vacChange", method = RequestMethod.POST)
public String changedVac(@RequestParam(value = "id", required = true) Integer id,
@RequestParam(value = "ort", required = true) String ort,
@RequestParam(value = "bereich", required = true) String bereich,
@RequestParam(value = "beschreibung", required = true) String beschreibung){
vacService.changeVacancyByID(id,gehalt,ort,bereich,beschreibung);
return "vacAdmin";
}
這是服務類的方法，我用：
void changeVacancyByID(Integer id, String gehalt,String ort,String bereich,String beschreibung);
}
的服務方法的實現：
public void changeVacancyByID(Integer id, String gehalt,String ort,String bereich,String beschreibung){
System.out.println("Edit method called");
VacancyEntity vacEntity = vacancyRepository.findOneById(id);
vacancyRepository.updateAttributes(id,gehalt,ort,bereich,beschreibung);
}
嗯，這是查詢我使用：
@Transactional
@Query (value = "UPDATE vacancy SET salary=?2, location=?3,functionality=?4, description=?5 WHERE id = ?1 ", nativeQuery = true)
void updateAttributes(Integer id, String gehalt, String ort, String bereich, String beschreibung);
此外VacancyEntity類，getter和setter還包括：
@Entity(name = "vacancy")
public class VacancyEntity {
@Id
@GeneratedValue
@Column(name = "id")
/**
* the vacancy identifier.
* "@Id": id is key attribute in database table vacancy.

這是一個完整的堆棧跟蹤：
Use execute or executeUpdate instead of executeQuery; SQL statement:

錯誤仍然存在，雖然 – Stan
這應該工作，應該清除的項目，重建，重新部署和重新測試。如果錯誤仍然存在，請發佈**完整**堆棧跟蹤（以及「VacancyEntity」的後期代碼）。 –
仍然無法正常工作，我現在添加了完整的堆棧跟蹤和VacancyEntity代碼 – Stan
