如何在JPA中的两列上运行SUM等聚合函数并显示其结果？

@Entity
@Table(name = "your_table_name")
public class YourEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "column1")
    private Integer column1;

    @Column(name = "column2")
    private Integer column2;

    // Getters and setters
}

public interface YourRepository extends JpaRepository<YourEntity, Long> {
    @Query("SELECT SUM(e.column1), SUM(e.column2) FROM YourEntity e")
    Object[] sumColumns();
}

@Service
public class YourService {
    private final YourRepository yourRepository;

    public YourService(YourRepository yourRepository) {
        this.yourRepository = yourRepository;
    }

    public void yourMethod() {
        Object[] result = yourRepository.sumColumns();
        Integer sumColumn1 = (Integer) result[0];
        Integer sumColumn2 = (Integer) result[1];
        System.out.println("Sum of column1: " + sumColumn1);
        System.out.println("Sum of column2: " + sumColumn2);
    }
}
