easypoi一个excel导出多sheet

public void downloadTheImporTemplate(HttpServletRequest request, HttpServletResponse response) {
		String classpath = ClassUtils.getDefaultClassLoader().getResource("").getPath();
		String downLoadPath = classpath + "/static/common/importTemplate/downloadTheImporTemplate.xls";
		TemplateExportParams params = new TemplateExportParams(downLoadPath);
		Integer[] sheetNum        = new Integer[] { 0,1,2 };
		params.setSheetNum(sheetNum);
		/* params.set */
		Map<String, Object> map = new HashMap<String, Object>();
		/* List<Map<String, Object>> listMap = new ArrayList<Map<String,Object>>(); */
		Workbook workbook = ExcelExportUtil.exportExcel(params, map);
		/* Workbook workbook = ExcelExportUtil.exportExcel(listMap,ExcelType.HSSF); */
		response.setContentType("application/msexcel;charset=UTF-8");
		EasyPoiUtil.downLoadExcel("设备信息导入模板.xls", response, workbook);
	}

关键代码:

Integer[] sheetNum        = new Integer[] { 0,1,2 };
		params.setSheetNum(sheetNum);

则导出的是前三页,以此类推
