Java中EasyPoi导出复杂合并单元格的⽅法
前⾔：
上星期做了⼀个Excel的单元格合并，⽤的是EasyPoi，我之前合并单元格都是原⽣的，第⼀次使⽤EasyPoi合并也不太熟悉，看着⽹上⾃⼰套⽤，使⽤后发现⽐原⽣的⽅便些，贡献⼀下，也给其他⽤到合并⽽且⽤的是EasyPoi的⼩伙伴节省下时间。

版本号，⾃⼰来定，可以去官⽹查看：
<!-- easypoi 导⼊包 -->
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-base</artifactId>
<version>4.0.0</version>
</dependency>
<dependency>
<groupId>cn.afterturn</groupId>
<artifactId>easypoi-annotation</artifactId>
<version>4.0.0</version>
</dependency>
实现代码：
/
/表头设置
List<ExcelExportEntity> colList = new ArrayList<ExcelExportEntity>();
ExcelExportEntity colEntity = new ExcelExportEntity("经销商", "distributorName");
colEntity.setNeedMerge(true);
colEntity.setWidth(20);
colList.add(colEntity);
colEntity = new ExcelExportEntity("科室", "dept");
colEntity.setNeedMerge(true);
colList.add(colEntity);
colEntity = new ExcelExportEntity("部门", "region");
colEntity.setNeedMerge(true);
colList.add(colEntity);
colEntity = new ExcelExportEntity("省份", "province");
colEntity.setNeedMerge(true);
colList.add(colEntity);
colEntity = new ExcelExportEntity("门店数量", "storeNum");
colEntity.setNeedMerge(true);
colEntity.setStatistics(true);
colList.add(colEntity);
Map<String, Integer> map = MonthStr());
Integer dayNum = ("dayNum");
for (int i = 1; i <= dayNum; i++) {
ExcelExportEntity group_1 = new ExcelExportEntity(i + "⽇", "day");
List<ExcelExportEntity> exportEntities = new ArrayList<>();
ExcelExportEntity appalyExcel = new ExcelExportEntity("申请数量", "applyNum" + i);
appalyExcel.setStatistics(true);
exportEntities.add(appalyExcel);
ExcelExportEntity adoptExcel = new ExcelExportEntity("通过数量", "adoptNum" + i);
adoptExcel.setStatistics(true);
exportEntities.add(adoptExcel);
java64位
group_1.setList(exportEntities);
colList.add(group_1);
}
/
/⽂件数据
List<Map<String, Object>> list = new ArrayList<>();
List<StoreNewAddReportVO.DistributorStoreNewAddReportVO> disList = StoreNewAddReportVO().getDistributorStoreNewAddReportVOList();
int size = disList.size();
for (int i = 0; i < size; i++) {
StoreNewAddReportVO.DistributorStoreNewAddReportVO dis = (i);
Map<String, Object> valMap = new HashMap<>();
valMap.put("distributorName", DistributorName());
valMap.put("dept", Dept());
valMap.put("region", Region());
valMap.put("province", Province());
valMap.put("storeNum", StoreNum());
List<StoreNewAddReportVO.dayData> dayDataList = DayDataList();
Map<String, List<StoreNewAddReportVO.dayData>> collectMap = wHashMap();
if (CollectionUtils.isNotEmpty(dayDataList)) {
collectMap = dayDataList.stream().upingBy(StoreNewAddReportVO.dayData::getDayStr));
}
List<Map<String, Object>> list_1 = new ArrayList<>();
Map<String, Object> valMap_1 = new HashMap<>();
for (int j = 1; j <= dayNum; j++) {
List<StoreNewAddReportVO.dayData> dayData = (String.valueOf(j));
int applyflag = 0;
int adoptflag = 0;
if (CollectionUtils.isNotEmpty(dayData)) {
applyflag = (0).getApplyNum();
adoptflag = (0).getAdoptNum();
}
valMap_1.put("applyNum" + j, applyflag);
valMap_1.put("adoptNum" + j, adoptflag);
}
list_1.add(valMap_1);
valMap.put("day", list_1);
list.add(valMap);
}
//导出
Workbook workbook = portExcel(new ExportParams("【" + MonthStr() + "】门店注册⽇明细数据", "数据"), colList, list);
Sheet sheet = Sheet("数据");
Row row = LastRowNum());
Cell cell = Cell(0);
cell.setCellValue("总计");
CellStyle cellStyle = ateCellStyle();
cellStyle.setAlignment(HorizontalAlignment.CENTER);//⽔平居中
cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);//垂直居中
Font font = ateFont();
font.setFontHeightInPoints((short) 15);
font.setFontName("Trebuchet MS");
cellStyle.setFont(font);
cell.setCellStyle(cellStyle);
CellRangeAddress range_0 = new LastRowNum(), LastRowNum(), 0, 3);
sheet.addMergedRegion(range_0);
File file = new File("D:\\".concat(UUID.randomUUID().toString().concat(".xls")));
FileOutputStream fileOutputStream = null;
try {
fileOutputStream = new FileOutputStream(file);
workbook.write(fileOutputStream);
} catch (Exception e) {
<("门店注册⽇workbook写⼊到⽂件中失败，错误信息：{}", StackTrace(e));
} finally {
if (null != fileOutputStream) {
try {
fileOutputStream.close();
} catch (IOException e) {
//skip
}
}
}
具体的API细节就不介绍了可以去官⽹，关键在于ExcelExportEntity 这个类，它是以map形式展现的，创建的时候设置key，设置value的根据key进⾏设置，上⾯⼀些StoreNewAddReportVO还有其他是我的业务类，到时候可以替换掉。
