导出运营数据Excel报表
产品原型
接口设计
ReportController

//查询概览数据

//2、通过POI将数据写入到Excel文件中
InputStream in = this.getClass().getClassLoader().getResourceAsStream("template/运营数据报表模版.xlsx");
try {
//基于模版文件创建一个新的Excel文件
XSSFWorkbook excel = new XSSFWorkbook(in);
//获取表格文件的Sheet页

//查询某一天的营业数据

//3、通过输出流将Excel文件下载到浏览器
ServletOutputStream out = response.getOutputStream();
excel.write(out);
//关闭资源
out.close();
excel.close();
