Java 无法提取结果集

现在，我正试图通过使用查询更新实体来更改数据库中的某些数据，但出现以下错误：

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

这是我的映射控制器：

@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";
}

这是我使用的服务类方法：

void changeVacancyByID(Integer id, String gehalt,String ort,String bereich,String beschreibung);

}

服务方法的实现：

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);

}

这就是我使用的查询：

@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，还包括VacancyEntity类、getter和setter：

@Entity(name = "vacancy")
public class VacancyEntity {
@Id
@GeneratedValue
@Column(name = "id")
/**

 * "@Id": id is key attribute in database table vacancy.

UPDATE

操作不会返回任何结果（您可以尝试在您喜爱的DB客户端中运行查询），因此spring在尝试从更新查询的结果构建

VacancyEntity

时失败。您还需要向查询中添加

@Modifying

要解决此问题，请将存储库更改为：

@Transactional
@Modifying
@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);

---

这应该是可行的，你应该清除项目，重建，重新部署和重新测试。如果错误仍然发生，发布完整的堆栈跟踪（同时发布

VacancyEntity

的代码）。仍然不工作，我现在添加了完整的堆栈跟踪和VacancyEntity代码尝试添加

@修改

到查询中。现在可以了，非常感谢。你能解释一下为什么有必要吗？
