考虑下面的代码,该代码从 mysqlDB 中提取名为“ice”的表。问题是我可以看到 IceCreamModel{id=101, description='vanilla', price=10, mulfactor=2} 。但在执行代码时无法查看“总计”psudo 列。

public interface IceCreamRepository extends jpaRepository<IceCreamModel,Integer> {

    @Query(value = "SELECT id, description,price, mulfactor, price * mulfactor as 'total' FROM ice WHERE id=101",nativeQuery = true)
    List<IceCreamModel> getMul();
}

    @Autowired
    private IceCreamRepository iceCreamRepository;

    public static void main(String[] args) {
        SpringApplication.run(DesignPatternsApplication.class, args); 
@Override
    public void run(String... args) throws Exception {
        getMul();
    }


    private void getMul() {
        List<IceCreamModel> list=iceCreamRepository.getMul();
        list.forEach(System.out::println);
    }

公共类 IceCreamModel 实现 Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private int id;
private  String description;
private int price;
private int mulfactor;

}
