如何将jsp数据导出到excel中
jsp通过POI导入导出Excel。 步骤：
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
// 第一步，创建一个webbook
HSSFWorkbook wb = new HSSFWorkbook();
// 第二步，添加一个sheet
HSSFSheet sheet = wb.createSheet("表一");
// 第三步，在sheet中添加表头
HSSFRow row = sheet.createRow((int) 0);
// 第四步，创建单元格
HSSFCellStyle style = wb.createCellStyle();
style.setAlignment(HSSFCellStyle.ALIGN_CENTER);
生成单元格内容
HSSFCell cell = row.createCell((short) 0);
cell.setCellValue("内容");
cell.setCellStyle(style);
cell = row.createCell((short) 1);
FileOutputStream fout = new FileOutputStream("D:/test.xls");
wb.write(fout);
fout.close();

如何把JSP页面导出到Excel中
jsp页面导出excel的话，刚好有做这个功能，可以参考如下代码：
function getExplorer() {
var explorer = window.navigator.userAgent;
// ie
if (explorer.indexOf("MSIE") >= 0 || (explorer.indexOf("Windows NT 6.1;") >= 0 && explorer.indexOf("Trident/7.0;") >= 0)) {
alert("识别你是IE浏览器1111======");
return 'ie';
}
// firefox
else if (explorer.indexOf("Firefox") >= 0) {
return 'Firefox';
}
// Chrome
else if (explorer.indexOf("Chrome") >= 0) {
return 'Chrome';
}
// Opera
else if (explorer.indexOf("Opera") >= 0) {
return 'Opera';
}
// Safari
else if (explorer.indexOf("Safari") >= 0) {
return 'Safari';
}
}
//设置导出的excel的标题
var excelTitle ="表格数据";
function toOutPutExcel(tableid,title) {// 整个表格拷贝到EXCEL中
excelTitle = title;
if (getExplorer() == 'ie') {
var curTbl = document.getElementById(tableid);
var oXL = new ActiveXObject("Excel.Application");
// 创建AX对象excel
var oWB = oXL.Workbooks.Add();
// 获取workbook对象
var xlsheet = oWB.Worksheets(1);
// 激活当前sheet
var sel = document.body.createTextRange();
sel.moveToElementText(curTbl);
// 把表格中的内容移到TextRange中
sel.select();
// 全选TextRange中内容
sel.execCommand("Copy");
// 复制TextRange中内容
xlsheet.Paste();
// 粘贴到活动的EXCEL中
oXL.Visible = true;
// 设置excel可见属性
try {
var fname = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");
} catch (e) {
print("Nested catch caught " + e);
} finally {
oWB.SaveAs(fname);
oWB.Close(savechanges = false);
// xls.visible = false;
oXL.Quit();
oXL = null;
// 结束excel进程，退出完成
// window.setInterval("Cleanup();",1);
idTmr = window.setInterval("Cleanup();", 1);
}
} else {
tableToExcel(tableid);
}
}
function Cleanup() {
window.clearInterval(idTmr);
CollectGarbage();
}
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-excel;base64,',
template = 'html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns=""head<!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>',
base64 = function(s) {
return window.btoa(unescape(encodeURIComponent(s)))
},
format = function(s, c) {
return s.replace(/{(\w+)}/g, function(m, p) {
return c[p];
})
}
return function(table, name) {
if (!table.nodeType)
table = document.getElementById(table)
var ctx = {
worksheet: excelTitle || 'Worksheet',
table: table.innerHTML
}
//window.location.href = uri + base64(format(template, ctx))
var titleDate= new Date().Format("yyyy-MM-dd hh-mm-ss");
document.getElementById("dlink").href = uri + base64(format(template, ctx));
document.getElementById("dlink").download = excelTitle+titleDate+".xls";
document.getElementById("dlink").click();
}
})()
怎么把JSP页面里的查询出来的数据导出到excel
jsp页面导出excel的话，刚好有做这个功能，可以参考如下代码：
function getExplorer() {
var explorer = window.navigator.userAgent;
// ie
if (explorer.indexOf("MSIE") >= 0 || (explorer.indexOf("Windows NT 6.1;") >= 0 && explorer.indexOf("Trident/7.0;") >= 0)) {
alert("识别你是IE浏览器1111======");
return 'ie';
}
// firefox
else if (explorer.indexOf("Firefox") >= 0) {
return 'Firefox';
}
// Chrome
else if (explorer.indexOf("Chrome") >= 0) {
return 'Chrome';
}
// Opera
else if (explorer.indexOf("Opera") >= 0) {
return 'Opera';
}
// Safari
else if (explorer.indexOf("Safari") >= 0) {
return 'Safari';
}
}
//设置导出的excel的标题
var excelTitle ="表格数据";
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
怎么从jsp页面的表格导出到Excel
无非是这样的一个过程。先通过数据库查询出数据，放到List里，然后把这个List发往页面，然后遍历这个List把数据显示到这个表格里。 要想把数据导出到execel，很简单，把页面接受的这个List用jxl写到Execel就行了。具体将List导出到Execel的类如下：
package cms.dao;
import java.io.IOException;
import java.io.OutputStream;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.List;
import javax.servlet.http.HttpServletResponse;
import jxl.Workbook;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import cms.utlis.DbUtils;
public class ToExecelByQuery {
//方法接受两个参数，一个是list，这个地方我用了泛型。另一个参数是HttpServletResponse response
public static void toExcelBy(List<AccessLog> list,HttpServletResponse response) {
// 创建工作表
WritableWorkbook book=null;
response.reset();
// 创建工作流
OutputStream os =null;
try {
// 设置弹出对话框
response.setContentType("application/DOWLOAD");
// 设置工作表的标题
response.setHeader("Content-Disposition", "attachment; filename=****.xls");//设置生成的文件名字
os = response.getOutputStream();
// 初始化工作表
book = Workbook.createWorkbook(os);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try{
//以下是我做的导出日志的一个模版
int nCount = list.size();
WritableSheet sheet = book.createSheet("访问日志", 0);
// 生成名为"商品信息"的工作表，参数0表示这是第一页
int nI = 1;
// 表字段名
sheet.addCell(new jxl.write.Label(0, 0, "日志编号"));
sheet.addCell(new jxl.write.Label(1, 0, "用户ID"));
sheet.addCell(new jxl.write.Label(2, 0, "用户姓名"));
sheet.addCell(new jxl.write.Label(3, 0, "访问日期"));
sheet.addCell(new jxl.write.Label(4, 0, "访问时间"));
sheet.addCell(new jxl.write.Label(5, 0, "名片ID"));
sheet.addCell(new jxl.write.Label(6, 0, "名片名称"));
sheet.addCell(new jxl.write.Label(7, 0, "创建日期"));
sheet.addCell(new jxl.write.Label(8, 0, "更新日期"));
// 将数据追加
for(int i=1;i<list.size();i++){
sheet.addCell(new jxl.write.Label(0, i, list.get(i).toString()));
sheet.addCell(new jxl.write.Label(1, i, list.get(i).getUserId()));
sheet.addCell(new jxl.write.Label(2, i, list.get(i).getUsername()));
sheet.addCell(new jxl.write.Label(3, i, list.get(i).getCrtTim()));
sheet.addCell(new jxl.write.Label(4, i, list.get(i).getComplTime()));
sheet.addCell(new jxl.write.Label(5, i, list.get(i).getCopId()));
sheet.addCell(new jxl.write.Label(6, i, list.get(i).getFirstname()));
sheet.addCell(new jxl.write.Label(7, i, list.get(i).getCrtTim()));
sheet.addCell(new jxl.write.Label(8, i, list.get(i).getUpdTim()));
}
book.write();
book.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
大体思路就是这样的，别忘了在你的项目中导入JXL必要的jar包，这个包叫jxl.jar，你可以下载一个。希望能帮到你，欢迎追问。望采纳！
