好的，根据您提供的表结构，以下是对应的Java实体类、持久层和业务类，并添加了注释。

Java实体类：

/**
 * 补单审批记录
 */
public class ReplenishOrderApprovalRecord {
    private Long id; // 主键ID
    private Long repRecordId; // 补单申请记录ID
    private String reason; // 审批批语
    private String operator; // 审核人
    private String remark; // 备注
    private Integer approvalNode; // 审批节点
    private Integer status; // 审核状态，0待审核，1已同意，2驳回
    private Date createTime; // 创建时间
    private Date updateTime; // 更新时间

    // getter和setter方法
}

持久层：

@Repository
public interface ReplenishOrderApprovalRecordMapper {
    /**
     * 新增补单审批记录
     */
    int insert(ReplenishOrderApprovalRecord record);

    /**
     * 根据ID查询补单审批记录
     */
    ReplenishOrderApprovalRecord selectById(Long id);

    /**
     * 更新补单审批记录
     */
    int update(ReplenishOrderApprovalRecord record);

    /**
     * 根据补单申请记录ID查询补单审批记录
     */
    List<ReplenishOrderApprovalRecord> selectByRepRecordId(Long repRecordId);
}

业务类：

@Service
public class ReplenishOrderApprovalRecordService {
    @Autowired
    private ReplenishOrderApprovalRecordMapper replenishOrderApprovalRecordMapper;

    /**
     * 新增补单审批记录
     */
    public int add(ReplenishOrderApprovalRecord record) {
        return replenishOrderApprovalRecordMapper.insert(record);
    }

    /**
     * 根据ID查询补单审批记录
     */
    public ReplenishOrderApprovalRecord getById(Long id) {
        return replenishOrderApprovalRecordMapper.selectById(id);
    }

    /**
     * 更新补单审批记录
     */
    public int update(ReplenishOrderApprovalRecord record) {
        return replenishOrderApprovalRecordMapper.update(record);
    }

    /**
     * 根据补单申请记录ID查询补单审批记录
     */
    public List<ReplenishOrderApprovalRecord> getByRepRecordId(Long repRecordId) {
        return replenishOrderApprovalRecordMapper.selectByRepRecordId(repRecordId);
    }
}

希望以上代码对您有所帮助。
