区块链项目节点奖励逻辑封装

Posted 2023-02-17 热心市民刘先生♛

前言

• 在当下区块链相关的应用项目种，一般会有质押奖励、锁仓奖励、节点奖励等等奖励。最为头疼的就是节点奖励。应为他的逻辑太过于复杂。从树状结构计算又需要拆分链路至上往下计算，从下往上统计数据。

bean 对象

@Data
public class UserBean 
    //用户id
    String userId;
    //节点级别
    String nodeRank;
    //对应节点的奖励级别比例
    String newAddP;
    //父类id
    String parentId;
    //理财宝金额
    BigDecimal allMoney;

    // 以上为传递参数，以下为计算参数不需要传值

    //分摊到每一条链路上的投资总额额度
    BigDecimal avgAllMoney;
    //该用户链路数
    int lineNum;




@Data
public class NotPageListBean 

    String lcLogId;

接口

public interface JdWardData 
   //节点奖励-获取所有用户并且与他购买的资产包数据
    List<UserBean> getUserList(String date);

    //节点奖励-获取最末端用户数据
    List<UserBean> getBranchUserList(String date);

    //获取当前未计算的理财包数据
    List<Map<String, Object>> getNotPageList(String date);

    //这次计算完成后，将刚刚未计算的理财包数据记录
    void insertNotPageList(List<Map<String, Object>> list,String date);

    //发放奖金到待领取表中，等待转账时间进行发放
    void insertLogMoeny(List<Map<String,Object>> maps25,List<Map<String,Object>> maps75);
