1.java导出excel报表：

package cn.jcenterhome.util;

import java.io.OutputStream;

import java.util.List;

import java.util.Map;

import javax.servlet.http.HttpServletResponse;

import jxl.Workbook;

public class ExportExcel {

public  final static String exportExcel(List header,

List> list,String xlsName,String

type,HttpServletResponse response) {

String result="系统提示：Excel文件导出成功！";

// 以下开始输出到EXCEL

try {

//定义输出流，以便打开保存对话框______________________begin

response.reset();// 清空输出流

response.setHeader("Content-disposition", "attachment;

filename="+ new String(xlsName.getBytes("GB2312"),"ISO8859-1"));

// 设定输出文件头

//定义输出流，以便打开保存对话框_______________________end

/** **********创建工作簿************ */

/** ************设置单元格字体************** */

WritableFont NormalFont = new WritableFont(WritableFont.ARIAL, 10);

sheets = new WritableSheet[scount];

for(int i=0;i

WritableSheet sheet = workbook.createSheet("Sheet"+i+1, i);

/** **********设置纵横打印(默认为纵打)、打印纸***************** */

jxl.SheetSettings sheetset = sheet.getSettings();

sheetset.setProtected(false);

sheets[i]=sheet;

}

/** ***************以下是EXCEL开头大标题，暂时省略********************* */

//sheet.mergeCells(0, 0, colWidth, 0);

//sheet.addCell(new Label(0, 0, "XX报表", wcf_center));

/** ***************以下是EXCEL第一行列标题********************* */

for(int j=0;j

for(int i=0;i

sheets[j].addCell(new Label(i, 0,header.get(i),wcf_center));

}

}

}else{

sheets = new WritableSheet[header.size()];

WritableSheet sheet = workbook.createSheet("Sheet"+1, 0);

/** **********设置纵横打印(默认为纵打)、打印纸***************** */

jxl.SheetSettings sheetset = sheet.getSettings();

for(int i=0;i

sheets[0].addCell(new Label(i, 0,header.get(i),wcf_center));

}

}

/** ***************以下是EXCEL正文数据********************* */

if(list!=null){

for (int i = 0; i < list.size(); i++)

{

Map value=list.get(i);

int s = ((i+1)/65535)+(((i+1)%65535)>0?1:0)-1;

System.out.println("export i position is :"+i+";s value is :"+s);

int j = i%65535;

WritableSheet sheet = sheets[s];

if(type.equals("exportAllOrder")){

sheet.addCell(new Label(0,

j+1,value.get("username")==null?"":value.get("username").toString(),wcf_left));

sheet.addCell(new Label(1, j+1,value.get("orderNo")==null?"":value.get("orderNo").toString(),wcf_left));

sheet.addCell(new Label(2,

j+1,value.get("ordertime")==null?"":value.get("ordertime").toString(),wcf_left));

sheet.addCell(new Label(3,

sheet.addCell(new Label(4,

String orderstatu=value.get("orderstatu")==null?"":value.get("orderstatu").toString();

String orderstatus="";

if(orderstatu.equals("0")){

orderstatus="未支付";

}else if(orderstatu.equals("1")){

orderstatus="已支付";

}else if(orderstatu.equals("-1")){

orderstatus="已取消";

}else if(orderstatu.equals("-2")){

orderstatus="已失效";

}

sheet.addCell(new Label(5, j+1,orderstatus,wcf_left));

sheet.addCell(new Label(6,

j+1,value.get("paymentway")==null?"":value.get("paymentway").toString(),wcf_left));

}

}

}

/** **********将以上缓存中的内容写到EXCEL文件中******** */

workbook.write();

/** *********关闭文件************* */

workbook.close();

} catch (Exception e) {

result="系统提示：Excel文件导出失败，原因："+ e.toString();

// System.out.println(result);

e.printStackTrace();

}finally{

if(list!=null)list.clear();

}

return result;

}

2.调用导出方法

List header=new ArrayList();

header.add("用户名");

header.add("订单号");

header.add("订单时间");

header.add("订单金额");

header.add("实际金额");

header.add("订单状态");

header.add("支付方式");

ExportExcel.exportExcel(header,list,"订单表.xls","exportAllOrder",response);

return null;

3.jsp页面，点击导出

导出

4.所使用jar包 jxl-2.6.jar
