Rest 无法提取结果集；嵌套异常为org.hibernate.exception.genericjdbception:无法提取结果集

我想插入一些数据，在插入之前，我想删除以前的相关数据。但出现“无法提取结果集；嵌套异常为org.hibernate.exception.genericjdbception:无法提取结果集”错误

我的控制器类

@PostMapping(path="signin",produces = "application/json")
@ResponseBody public LoginView loginProcess( @RequestBody User user){

try {
    DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
    Date date = new Date();
    Date newdate = new Date(date.getTime()+9*3600*1000);

this.loginRepository.delete(user.getUsername());
this.loginRepository.insert(user.getUsername(),user.getDetails(),dateFormat.format(date),dateFormat.format(newdate));

catch(Exception e) {
        System.out.println(e.getMessage());
    }
}

存储库类

public interface LoginRepository extends JpaRepository<User, Integer>{


@Query(value="INSERT INTO DBA.TOKEN_DETAILS (username,TOKEN,ACTIVE,VALID_FROM,VALID_TO) VALUES(:username,:token,1,:validFrom,:validTo)",nativeQuery=true)
public void insertToken(@Param("username")String username, @Param("token")String token, @Param("validFrom")String validFrom, @Param("validTo")String validTo);

@Transactional
@Modifying 
@Query(value="DELETE FROM DBA.TOKEN_DETAILS WHERE username=?1",nativeQuery=true)
public void deleteToken(String username);

}

@Modifying
    @Query(value="INSERT INTO DBA.TOKEN_DETAILS (username,TOKEN,ACTIVE,VALID_FROM,VALID_TO) VALUES(:username,:token,1,:validFrom,:validTo)",nativeQuery=true)
    public void insertToken(@Param("username")String username, @Param("token")String token, @Param("validFrom")String validFrom, @Param("validTo")String validTo);

通过在repository类中添加@Modify注释解决了这个问题

public interface LoginRepository extends JpaRepository<User, Integer>{


@Query(value="INSERT INTO DBA.TOKEN_DETAILS (username,TOKEN,ACTIVE,VALID_FROM,VALID_TO) VALUES(:username,:token,1,:validFrom,:validTo)",nativeQuery=true)
public void insertToken(@Param("username")String username, @Param("token")String token, @Param("validFrom")String validFrom, @Param("validTo")String validTo);

@Transactional
@Modifying 
@Query(value="DELETE FROM DBA.TOKEN_DETAILS WHERE username=?1",nativeQuery=true)
public void deleteToken(String username);

}

@Modifying
    @Query(value="INSERT INTO DBA.TOKEN_DETAILS (username,TOKEN,ACTIVE,VALID_FROM,VALID_TO) VALUES(:username,:token,1,:validFrom,:validTo)",nativeQuery=true)
    public void insertToken(@Param("username")String username, @Param("token")String token, @Param("validFrom")String validFrom, @Param("validTo")String validTo);

正在插入数据，但代码抛出错误。
