Springboot写导出excel

导出excel

这里是写的一个日志记录列表导出的，其实都是一样的(java),，前端直接就是写个按钮调用接口就行。这里做个记录方便以后直接C+V

	@Autowired
	private ILogService 

	@RequestMapping(value = "/export/excelDownloads", method = RequestMethod.GET)
    public void downloadAllClassmate(HttpServletResponse response) throws IOException {
     
        HSSFWorkbook workbook = new HSSFWorkbook();
        HSSFSheet sheet = workbook.createSheet("信息表");

        List<Log> logList = ILogService.list();

        String fileName = "exportLogInf"  + ".xls";//设置要导出的文件的名字
        //新增数据行，并且设置单元格数据

        int rowNum = 1;

        String[] headers = {
      "操作用户", "操作内容", "操作事件", "IP地址","操作结果"};
        //headers表示excel表中第一行的表头

        HSSFRow row = sheet.createRow(0);
        //在excel表中添加表头

        for(int i=0;i<headers.length;i++){
     
            HSSFCell cell = row.createCell(i);
            HSSFRichTextString text = new HSSFRichTextString(headers[i]);
            cell.setCellValue(text);
        }

        //在表中存放查询到的数据放入对应的列
        for (Log log : logList) {
     
            HSSFRow row1 = sheet.createRow(rowNum);
            row1.createCell(0).setCellValue(log.getUserName());
            row1.createCell(1).setCellValue(log.getOperation());
            row1.createCell(2).setCellValue(log.getCreateTime());
            row1.createCell(3).setCellValue(log.getIp());
			row1.createCell(3).setCellValue(log.getOperationType());
            rowNum++;
        }

        response.setContentType("application/octet-stream");
        response.setHeader("Content-disposition", "attachment;filename=" + fileName);
        response.flushBuffer();
        workbook.write(response.getOutputStream());
    }

最后直接访问 ip:port +项目名/export/excelDownload
