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) {        this.rebateRuleName = 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

package com.ybl.test.threetiercurd.bean;import java.util.List;/** * Created by szh on 2017/11/28. */public class ThreeTierVO {    public String mediaName;    List<RebateRuleTest> rebateRuleTestList;    public String getMediaName() {        return mediaName;    }    public void setMediaName(String mediaName) {        this.mediaName = mediaName;    }    public List<RebateRuleTest> getRebateRuleTestList() {        return rebateRuleTestList;    }    public void setRebateRuleTestList(List<RebateRuleTest> rebateRuleTestList) {        this.rebateRuleTestList = rebateRuleTestList;    }}
