参考代码：
public String export(){
Workbook workBook = null;
try {
//
List<Map<String, Object>> sheetsList = new ArrayList<>();
List<DeptUtil> exportList = exportService.exportList();
// 创建参数对象（用来设定excel得sheet得内容等信息）
ExportParams deptExportParams = new ExportParams();
// 设置sheet得名称
deptExportParams.setSheetName("员工报表1");
// 创建sheet1使用得map
Map<String, Object> deptExportMap = new HashMap<>();
// title的参数为ExportParams类型，目前仅仅在ExportParams中设置了sheetName
deptExportMap.put("title", deptExportParams);
// 模版导出对应得实体类型
deptExportMap.put("entity", DeptUtil.class);
// sheet中要填充得数据
deptExportMap.put("data", exportList);
sheetsList.add(deptExportMap);
// 创建参数对象（用来设定excel得sheet得内容等信息）
ExportParams empExportParams = new ExportParams();
empExportParams.setSheetName("员工报表2");
// 创建sheet2使用得map
Map<String, Object> empExportMap = new HashMap<>();
empExportMap.put("title", empExportParams);
empExportMap.put("entity", DeptUtil.class);
empExportMap.put("data", exportList);
sheetsList.add(empExportMap);
// 执行方法
workBook = ExcelExportUtil.exportExcel(sheetsList, ExcelType.HSSF);
fileName = URLEncoder.encode("员工报表导出", "UTF-8");
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
workBook.write(outputStream);
outputStream.flush();
byte[] byteArray = outputStream.toByteArray();
excelStream = new ByteArrayInputStream(byteArray,0,byteArray.length);
outputStream.close();
}catch (Exception e){
e.printStackTrace();
}finally {
