一、实现代码 使用Map方式添加head头，对应填充值
/**
* 导出查看发车明细
* @param query
* @return
*/
@Override
public ExportResult monthResourcePlanDepartureProgressDetailsExportExcelData(ResourceSituationListQuery query) {
log.info("导出参数:{}",DstJsonUtil.toString(query));
//List<ResourcePlanShipDetailVO> shipDetail = resourcePlanService.getShipDetail(query);
List<ResourcePlanShipDetailVO> shipDetail = resourceSituationCoreService.getCodData();
if (CollectionUtils.isEmpty(shipDetail)) {
log.error("导出数据为空");
return null;
}
List<String> dispatchDate = new ArrayList<>();
shipDetail.stream().forEach(e->{
e.getShipDetails().stream().forEach(it->{
dispatchDate.add(DstDateUtil.format(it.getDispatchDate(),DstDateUtil.Y_M_D));
});
});
List<String> newDispatchDate = Lists.newArrayList(new HashSet(dispatchDate));
List<String> newDispatchDateList = newDispatchDate.stream().sorted().collect(Collectors.toList());
List<String> monthAndDays = new ArrayList<>();
for (String date : newDispatchDateList) {
monthAndDays.add(date);
}
List<String> headers = new ArrayList<String>() {
{
add("数据类型");
add("资源情况编码");
add("关联发车计划编码");
add("大区城市");
add("车辆品牌（属性）");
add("车辆型号（属性）");
add("车型族群（属性）");
add("电池包度数（属性）");
add("电池包厂商（属性）");
add("车辆用途（属性）");
add("发车总数");
addAll(monthAndDays);
}
};
List<String> columns = new ArrayList<String>() {
{
add("dataType");
add("resourceSituationCode");
add("shipCode");
add("cityName");
add("carBrandName");
add("carModelName");
add("carModelGroupName");
add("esdTotalPowerName");
add("esdCompanyName");
add("vehicleUseName");
add("needShipCountTotal");
addAll(monthAndDays);
}
};
List<Map<String, Object>> mapDatas = new ArrayList<>();
shipDetail.forEach(p -> {
mapDatas.add(converItemToMap(p,1,monthAndDays));
mapDatas.add(converItemToMap(p,2,monthAndDays));
});
return ExportResult.wrap(headers, columns, mapDatas, 1);
}
二、核心转换方法
/**
* @Description 转换map
* @Param item type 1:计划发车 2:实际发车
* @Return java.util.Map<java.lang.String,java.lang.Object>
* @Date 2024/3/12 18:59
* @Author lwp
*/
private Map<String,Object> converItemToMap(ResourcePlanShipDetailVO item,Integer type,List<String> monthAndDays){
Map<String,Object> temp =new HashMap<>();
String dataType = type == 1 ? "计划发车" :"实际发车";
Integer needShipCountTotal = type == 1 ? item.getTotalAssignCount() : item.getTotalShipCount();
temp.put("dataType", dataType);
temp.put("resourceSituationCode",item.getResourceSituationCodes());
temp.put("shipCode",item.getShipCodes());
temp.put("cityName",item.getFullCityName());
temp.put("carBrandName",item.getCarBrandName());
temp.put("carModelName",item.getCarModelName());
temp.put("carModelGroupName",item.getCarModelGroupName());
temp.put("esdTotalPowerName",item.getEsdTotalPowerName());
temp.put("esdCompanyName",item.getEsdCompanyName());
temp.put("vehicleUseName",item.getVehicleUseName());
temp.put("needShipCountTotal",needShipCountTotal);
item.setShipDetails(item.getShipDetails().stream().sorted(Comparator.comparing(AssignDetailVO::getDispatchDate))
.collect(Collectors.toList()));
for (String monthAndDay : monthAndDays) {
A: for (AssignDetailVO shipDetail : item.getShipDetails()) {
String dispatchDate = DstDateUtil.format(shipDetail.getDispatchDate(), DstDateUtil.Y_M_D);
if (dispatchDate.equals(monthAndDay)) {
temp.put(monthAndDay, type == 1 ? shipDetail.getDispatchNum() : shipDetail.getShipCount());
break A;
} else {
temp.put(monthAndDay, type == 1 ? 0 : 0);
}
}
}
temp = MapUtils.sortMapByKey(temp);
return temp;
}
三、导出实体类
package com.dst.steed.fulfillment.common.domain.biz.resourceplan;
import com.dst.steed.common.convert.translation.Translation;
import lombok.Data;
import java.util.List;
/**
* 资源计划发车明细
*/
@Data
public class ResourcePlanShipDetailVO {
/**
* 资源情况编码
*/
private String resourceSituationCodes;
/**
* 发车计划编码
*/
private String shipCodes;
/**
* 城市编码
*/
@Translation(convertName = "convertRegionAndCityName", convertTo = "fullCityName")
private String cityCode;
/**
* 城市名称
*/
private String fullCityName;
/**
* 车辆品牌
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-carBrandName")
private String carBrand;
private String carBrandName;
/**
* 车辆型号
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-carModelName")
private String carModel;
private String carModelName;
/**
* 车型族群
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-carModelGroupName")
private String carModelGroup;
private String carModelGroupName;
/**
* 动力电池包电量
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-esdTotalPowerName")
private String esdTotalPower;
private String esdTotalPowerName;
/**
* 动力电池包厂商
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-esdCompanyName")
private String esdCompany;
private String esdCompanyName;
/**
* 资产分类
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-assetClassifyName")
private String assetClassify;
private String assetClassifyName;
/**
* 车辆用途
*/
@Translation(convertName = "commonConvertAttrValueIdMapValue",convertTo = "attrValueName-vehicleUseName")
private String vehicleUse;
private String vehicleUseName;
/**
* 发车总计-计划发车量
*/
private Integer totalAssignCount;
/**
* 发车总计-已发车量
*/
private Integer totalShipCount;
/**
* 发车总计-剩余量
*/
private Integer totalResidueCount;
/**
* 发车明细
*/
private List<AssignDetailVO> shipDetails;
}
实体类属性明细类
package com.dst.steed.fulfillment.common.domain.biz.resourceplan;
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;
import java.util.Date;
/**
* 分配详情VO
*/
@Data
public class AssignDetailVO {
/**
* 中心分配ID
*/
private String id;
/**
* 分配类型 1. 中心分配 2. 大区分配
*/
private Integer referenceType;
/**
* 发车日期
*/
@JsonFormat(pattern = "M月d日", timezone = "GMT+8")
private Date dispatchDate;
/**
* 中心分配发车数量
*/
private Integer centerDispatchNum;
/**
* 城市计划发车数量
*/
private Integer dispatchNum;
/**
* 实际发车数量(发车明细字段)
*/
private Integer shipCount;
}
四、展示效果
以有数据的日期展示导出头
