如何推广自己的公司杭州优化seo

前端方法：调用exportInfoPid这个方法并传入要查询的id即可，也可以用其他参数看个人需求

function exportInfoPid(id){window.location.href = 服务地址+"/exportMdsRoutePid/"+id;
}

后端控制层代码

@Controller
@Scope("prototype")
@RequestMapping("mms/mds/mdsroute/mdsRouteController")
public class MdsRouteController implements LoaderConstant {
@Autowired
private MdsRouteAPI mdsRouteAPI;
@Autowired
private MdsRouteExportExcel mdsRouteExportExcel;/*** 工艺导出** @param pid* @param request* @return* @throws Exception*/@RequestMapping(value = "/operation/exportMdsRoutePid/{pid}")public Boolean exportMdsRoutePid(@PathVariable String pid, HttpServletRequest request,HttpServletResponse response) throws Exception {ModelAndView mav = new ModelAndView();//查询数据MdsRouteDTO mdsRouteDTO = mdsRouteAPI.getRouteSeqTime(pid);//查询到的数据写入ExeclmdsRouteExportExcel.mdsExportExcel(response,mdsRouteDTO);return true;}
}

通过一下方法创建多个Sheet表，要几个创建几个

Sheet sheet2 = wb.createSheet("工序信息");

Execl写入并返回信息到服务端

}

 单元格背景色的设置目前没试验出来，可能是我用的版本有冲突吧，网上查的结果是这两个函数，可以自己尝试，单元格的设置可以了解一下CellStyle

cellStyleHead.setFillBackgroundColor(IndexedColors.CORNFLOWER_BLUE.getIndex());
cellStyleHead.setFillPattern(FillPatternType.SOLID_FOREGROUND);;
