JAVA WEB用POI导出EXECL多个Sheet

发布时间:2023年12月22日

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Execl
        mdsRouteExportExcel.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

package avicit.mms.mds.mdsroute.controller;

?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);;
