业务需求与设计

一个媒体可以创建多条返点规则

返点规则 分为 阶梯返点 / 固定返点

阶梯返点 分为 返点下限 与 返点上限 以及 返点率

固定返点 分为 返点率

设计

返点规则 - 》 返点规则 JavaBean

返点明细 -》  返点明细 JavaBean

返点规则 下面有 返点明细(固定/阶梯)。

返点明细

package com.ybl.test.threetiercurd.bean;
     
    /**
     * Created by szh on 2017/11/28.
     */
    public class RebateTest {
     
        private String rebateFloor;
     
        private String rebateUpper;
     
        private String fixedUpper;
     
        public String getRebateFloor() {
            return rebateFloor;
        }
     
        public void setRebateFloor(String rebateFloor) {
            this.rebateFloor = rebateFloor;
        }
     
        public String getRebateUpper() {
            return rebateUpper;
        }
     
        public void setRebateUpper(String rebateUpper) {
            this.rebateUpper = rebateUpper;
        }
     
        public String getFixedUpper() {
            return fixedUpper;
        }
     
        public void setFixedUpper(String fixedUpper) {
            this.fixedUpper = fixedUpper;
        }
    }

返点规则

package com.ybl.test.threetiercurd.bean;
     
    import java.util.List;
     
    /**
     * Created by szh on 2017/11/28.
     */
    public class RebateRuleTest {
     
        private String rebateRuleName;
     
        private Integer rebateRuleType;
     
        private List<RebateTest> rebateTestList;
     
        public Integer getRebateRuleType() {
            return rebateRuleType;
        }
     
        public void setRebateRuleType(Integer rebateRuleType) {
            this.rebateRuleType = rebateRuleType;
        }
     
        public String getRebateRuleName() {
            return rebateRuleName;
        }
     
        public void setRebateRuleName(String rebateRuleName) {

        }
     
        public List<RebateTest> getRebateTestList() {
            return rebateTestList;
        }
     
        public void setRebateTestList(List<RebateTest> rebateTestList) {
            this.rebateTestList = rebateTestList;
        }
    }

媒体下的返点规则列表
