【项目实战】Java POI之Excel导出经典案例一

最近项目中需要用到数据的导出， 于是乎就做几个，其实说白了还是利用apache的poi，在项目中直接导入poi包就可以。多的就不用说了，我直接上代码。

1、首先准备一些poi的jar包，如下图：



2、在项目工程都创建一张Excel表，存放某个目录下。图图如下：



3、在JSP页面添加一个导出Excel按钮。如下：



4、Java后台Controller导出方法我就不过多解释，我直接
如下：

/**
* 导出Excel功能
* @return

@RequestMapping(value = "queryAuditGroupExcelList.htm")
public void queryAuditGroupExcelList(HttpServletRequest request,HttpServletResponse response,
HttpServletResponse reponse, ModelMap model, Integer groupId) {

Integer bizId = WebUtils.getCurBizId(request);
//获取信息1
Map map= financeService.queryAuditViewInfo(groupId, bizId);

Map groupMap = (Map) map.get("group");//获取到团信息
//获取信息2
Map<String, Object> pm = WebUtils.getQueryParamters(request);
List<Map<String, Object>> orderList = getCommonService(null).queryList("fin.selectOrderList", pm);

//获取信息3
//List<InfoBean> del_list = (List) map.get("del");
List<Map<String, Object>> deliveryList = getCommonService(null).queryList("fin.selectDeliveryList", pm);

//获取信息4
List<InfoBean> list = (List) map.get("sup");

Map<String, Object> order_pm = WebUtils.getQueryParamters(request);
List<Map<String, Object>> supplierList = getCommonService(null).queryList("fin.selectSupplierList", pm);

//获取信息5
