EasyExcel简单导出

@ApiOperation("导出历史上送记录")
@PostMapping(value = "/exportSend", produces = "application/octet-stream")
public void exportExcel(@RequestBody ExportSendVO sendVO, HttpServletResponse response) throws Exception {

    // 获取数据
    List<MessageExportVO> result = ssMessageManageService.exportSend(sendVO);
    // 设置 HTTP 响应头信
    response.setContentType("application/vnd.ms-excel");
    response.setHeader("Access-Control-Expose-Headers","Content-Disposition");
    response.setHeader("Content-disposition", "attachment;filename=" + URLEncoder.encode("历史上送记录.xlsx", "utf-8"));
    response.setCharacterEncoding("utf-8");


    // 使用 EasyExcel 写入数据到响应的输出流
    EasyExcel.write(response.getOutputStream(), MessageExportVO.class)
            .sheet("历史上送记录")
            .doWrite(result);

}

 注意点！！！！

 定义的VO类  处理时间
