easy-poi实现动态列(标题)、多sheet导出excel

一个sheet动态导出、伪代码，创建填充后的workbook对象

List>list = new ArrayList>();
HashMap map = new HashMap<>();
map.put("name", "小明");
map.put("age", "18");
list1.add(map);
List entitys=new ArrayList<>();
entitys.add(new ExcelExportEntity("名字" ,"name"));
entitys.add(new ExcelExportEntity("年龄" ,"age"));
ExportParams exportParams = new ExportParams(null, "sheet1名字");
exportParams.setType(ExcelType.XSSF);
Workbook workbook = ExcelExportUtil.exportExcel(exportParams, entitys, list);

多个sheet动态导出、伪代码，创建填充后的workbook对象

List> sheet1ListMap= new ArrayList>();
 
List> sheet2ListMap= new ArrayList>();
 
List sheet1List=new ArrayList<>();
sheet1List.add(new ExcelExportEntity("名字" ,"name"));
sheet1List.add(new ExcelExportEntity("年龄" ,"age"));
 
List sheet2List=new ArrayList<>();
sheet2List.add(new ExcelExportEntity("学号" ,"sno"));
sheet2List.add(new ExcelExportEntity("课程" ,"course"));
 
ExportParams exportParams1 = new ExportParams(null, "sheet1名字");
exportParams1.setType(ExcelType.XSSF);
 
ExportParams exportParams2 = new ExportParams(null, "sheet2名字");
exportParams2.setType(ExcelType.XSSF);
 
Workbook workbook = new XSSFWorkbook();
ExcelExportService service = new ExcelExportService();
// 创建sheet1,执行的先后顺序
service.createSheetForMap(workbook, exportParams1, sheet1List, sheet1ListMap);
// 创建sheet2
service.createSheetForMap(workbook, exportParams2, sheet2List, sheet2ListMap);

 注意：方法createSheetForMap（）是有使用限制的，导出的数据不能为null。假如需要导出只用表头，没有数据的的表单，需要创建对应的实体类，使用注解的方式
