最近项目有导出数据到excel功能，于是觉得很轻松的写了下面代码
@ApiOperation(value = "万级数据导出")
@RequestMapping(value = "/export1",method = RequestMethod.GET)
public void exportExcel1(HttpServletResponse response, HttpServletRequest request) throws Exception{
//接收参数
String accounttime = request.getParameter("accounttime");
//创建poi导出数据对象
//SXSSFWorkbook sxssfWorkbook = new SXSSFWorkbook();
//创建sheet页
//SXSSFSheet sheet = sxssfWorkbook.createSheet("测试1");
XSSFWorkbook sxssfWorkbook = new XSSFWorkbook();
XSSFSheet sheet = sxssfWorkbook.createSheet("测试1");
//创建表头
XSSFRow headRow = sheet.createRow(0);
//设置表头信息
headRow.createCell(0).setCellValue("序号");
headRow.createCell(1).setCellValue("姓名");
headRow.createCell(2).setCellValue("年龄");
// 遍历上面数据库查到的数据
for(int i =1;i |
