❶ struts2 中要在jsp页面上实现把数据库中的数据导成excel,在页面上点击导出时excel时，弹出下载保存框。
struts1我做过一个类似的。用jxl导入excel文件,获取里面的信息并修改,再将修改后的excel导出。struts2就不知道了。
❷ 如何将jsp页面表格另存为excel格式报表,或通过打印生成.xsl报表
看看下面的代码，应该对你有帮助：

❸ jsp页面的数据怎么样导出到excel表格
方法一：
function saveCode(obj) {
var winname = window.open('', '_blank', 'top=10000');
var strHTML = document.all.tableExcel.innerHTML;
winname.document.open('text/html', 'replace');
winname.document.writeln(strHTML);
winname.document.execCommand('saveas','','excel.xls');
winname.close();
}
方法二：
// Excel导出2
/**
如果javaScript报“Automation 服务器不能创建对象”，则按下方解决。
打开Internet Explorer “工具”菜单栏中的“选项”一栏，单击“安全”栏中的“自定义级别”选项卡，
将第三项“对没有标记为安全的activex控件进行初始化和脚本运行”设置成“启用”即可。
*/
function exportExecl(tableId) {
var table=document.getElementById(tableId);
var oXL = new ActiveXObject("Excel.Application");
var oWB = oXL.Workbooks.Add();
var oSheet = oWB.ActiveSheet;
var sel=document.body.createTextRange();
sel.moveToElementText(table);
sel.select();
sel.execCommand("Copy");
oSheet.Paste();
oXL.Visible = true;
}
这里的tableId为表格的id

❼ java项目中怎么实现jsp页面Excel模板下载并弹框。
controller层关键代码：
@RequestMapping(value="/excel")
publicModelAndViewexportExcel()throwsException{
ModelAndViewmv=newModelAndView();
PageDatapd=newPageData();
pd=this.getPageData();
Map<String,Object>dataMap=newHashMap<String,Object>();
List<String>titles=newArrayList<String>();
titles.add("办事处");//1
titles.add("当日新增扫码商户（个）");//2
titles.add("当日交易笔数（笔）");//3
titles.add("当日交易金额");//4
titles.add("当日收益");//5
titles.add("累计新增扫码商户（个）");//6
titles.add("累计交易笔数（笔）");//7
titles.add("累计交易金额");//8
titles.add("累计收益");//9
dataMap.put("titles",titles);
Pagepage=newPage();
page.setPd(pd);
List<PageData>varOList=agencyService.list(page);
List<PageData>varList=newArrayList<PageData>();
for(inti=0;i<varOList.size();i++){
PageDatavpd=newPageData();
vpd.put("var1",varOList.get(i).get("AGENCYNAME").toString());//1
vpd.put("var2",varOList.get(i).get("TODAYINSTALL").toString());//2
vpd.put("var3",varOList.get(i).get("TODAYTRANS").toString());//3
vpd.put("var4",varOList.get(i).get("TODAYPRICE").toString());//4
vpd.put("var5",varOList.get(i).get("TODAYPAYMENT").toString());//5
vpd.put("var6",varOList.get(i).get("TOTALINSTALL").toString());//6
vpd.put("var7",varOList.get(i).get("TOTALTRANS").toString());//7
vpd.put("var8",varOList.get(i).get("TOTALPRICE").toString());//8
vpd.put("var9",varOList.get(i).get("TOTALPAYMENT").toString());//9
varList.add(vpd);
}
dataMap.put("varList",varList);
ObjectExcelViewerv=newObjectExcelView();
mv=newModelAndView(erv,dataMap);
returnmv;
}

for(inti=0;i<len;i++){//设置标题
Stringtitle=titles.get(i);
cell=getCell(sheet,0,i);
cell.setCellStyle(headerStyle);
setText(cell,title);
}
sheet.getRow(0).setHeight(height);
HSSFCellStylecontentStyle=workbook.createCellStyle();//内容样式

List<PageData>varList=(List<PageData>)model.get("varList");
