イム私のJPAリポジトリを更新しようと更新クエリ
@Transactional
public interface UserRepository extends JpaRepository<User, Integer> {
User findByUsername(String username);
User findById(Long id);
@Query(value = "update user t set t.rule_id = NULL where t.rule_id = :id", nativeQuery = true)
List<User> setNUll(@Param("id") String id);}
これは私のコントローラの一部です:
@RequestMapping(value = "/admin/rule/{id}/edit", method = RequestMethod.GET)
public String editRule(@PathVariable Integer id, Model model)
{
userService.setNUll(Integer.toString(id));
model.addAttribute("rule", ruleCrudService.getRuleById(id));
updateUserData();
return "ruleForm";
}
そして、このエラーが私のブラウザでapears:
There was an unexpected error (type=Internal Server Error, status=500). could not extract ResultSet; nested exception is org.hibernate.exception.GenericJDBCException: could not extract ResultSet
サーバーには次のように記載されています。
