如果你想导入excel:请参考:http://blog.csdn.net/xuanzhangran/article/details/71603478
或者:http://blog.csdn.net/xuanzhangran/article/details/70158995
本框架使用ssm。
1:点击导出订单,按照你的查询田间导出数据,如果没有查询条件就全部导出。
2:在调用工具类的时候需要导包,
3:所以需要在eclipse里导入
4:jia包下载路径,无需c币:http://download.csdn.net/detail/xuanzhangran/9813051
5:仔细看完代码即可实现。
前台代码:
function orderExport(){
var orderNumber = $("#orderNumber").val();
var userName = $("#userName").val();
var mobile = $("#mobile").val();
var status = $("#status").val();
var startTime = $("#startTime").val();
var endTime = $("#endTime").val();
window.location.href = "/orderExport.html?orderNumber="+orderNumber+"& userName="+userName+
"&mobile="+mobile+"&status="+status+"&startTime="+startTime+"&endTime="+endTime;
}
//点击导出按钮调用function orderExport()需要查询的数据的条件带过去
后台代码:
@RequestMapping("/orderExport.html")
public void orderExport( HttpServletRequest request,
@RequestParam(value="userName",required = false)String userName,
@RequestParam(value="mobile",required = false)String mobile,
@RequestParam(value="orderNumber",required = false)String
@RequestParam(value="status",required = false)Byte status,
@RequestParam(value = "startTime", required = false) String startTime1,
@RequestParam(value = "endTime", required = false) String endTime1,
HttpServletResponse response){
//此处为查询的条件
SuBusiness business=WebUtil.getLoginUser(request);//登录人信息
business=SuBusinessService.selectByPhone(business.getMobile());
Map
map.put("sellerBusinessId", business.getId());
if(StringUtils.isNotBlank(userName)){
map.put("userName", userName);
}else{
map.put("userName", null);
}
if(StringUtils.isNotBlank(mobile)){
map.put("mobile", mobile);
}else{
map.put("mobile", null);
}
if(StringUtils.isNotBlank(orderNumber)){
map.put("orderNumber", orderNumber);
}else{
map.put("orderNumber", null);
}
Date startTime = null;
Date endTime = null;
if(StringUtils.isNotBlank(startTime1)){
String startTimeStr = startTime1+" 00:00:00";
String endTimeStr = "";
if(StringUtils.isBlank(endTime1)){
endTimeStr = DateUtil.format(new Date(),"yyyy-MM-dd")+" 23:59:59";
}else{
endTimeStr = endTime1+" 23:59:59";
}
startTime = DateUtil.parse(startTimeStr, "yyyy-MM-dd HH:mm:ss");
endTime = DateUtil.parse(endTimeStr, "yyyy-MM-dd HH:mm:ss");
map.put("startTime", startTime);
map.put("endTime", endTime);
}else{
map.put("startTime", null);
map.put("endTime", null);
}
if(status.intValue()!=99){
map.put("status", status);
}else {
if (status.intValue()==0) {
map.put("status", 0);
}else {
map.put("status", null);
}
}
//进行查询并导出
List
if (orderList != null && orderList.size()>0) {//查询的数据不为空就对数据进行导出
//导出文件的标题
String title = "商城订单"+DateUtil.format(new Date(), "yyyyMMdd")+".xls";
//设置表格标题行
String[] headers = new String[] {"序号","订单号", "花匠名称","订单时间","状态", "消费总额", "退款金额"};
List
Object[] objs = null;
for (Order order : orderList) {//循环每一条数据
objs = new Object[headers.length];
objs[0] = order.getOrderNumber();//序号
objs[1] = order.getOrderNumber();//订单号
objs[2] = order.getUser().getRealname()+" "+order.getUser().getMobile();//花匠信息
if (order.getCreateDateTime() != null) {
objs[3] = DateUtil.format(order.getCreateDateTime(), "yyyy-MM-dd HH:mm:ss");//订单时间
}else {
objs[3] = "无";
}
if (order.getStatus().intValue() == -1) {
objs[4] = "未发货,申请退款";//状态
}
if (order.getStatus().intValue() == 0) {
objs[4] = "已取消";//状态
}
if (order.getStatus().intValue() == 1) {
objs[4]="待支付";//状态
}
if (order.getStatus().intValue() == 2) {
objs[4] = "待发货";//状态
}
objs[5]=order.getPay();//消费金额
if (order.getRefundMoney() != null) {
objs[6] = order.getRefundMoney();//退货金额
}else {
objs[6] = "0.0";
}
//数据添加到excel表格
dataList.add(objs);
}
//使用流将数据导出
OutputStream out = null;
try {
//防止中文乱码
String headStr = "attachment; filename=\"" + new String( title.getBytes("gb2312"), "ISO8859-1" ) + "\"";
response.setContentType("octets/stream");
response.setContentType("APPLICATION/OCTET-STREAM");
response.setHeader("Content-Disposition", headStr);
out = response.getOutputStream();
//ExportExcel ex = new ExportExcel(title, headers, dataList);//有标题
ExportExcelSeedBack ex = new ExportExcelSeedBack(title, headers, dataList);//没有标题
ex.export(out);
} catch (Exception e) {
e.printStackTrace();
}
}
}
需要调用的工具类:ExportExcelSeedBack
如上操作会出现ExportExcelSeedBack错误:原因是因为是没有定义他的工具类,工具类如下:
public class ExportExcelSeedBack {
//显示的导出表的标题
private String title;
//导出表的列名
private String[] rowName ;
private List
HttpServletResponse response;
//构造方法,传入要导出的数据
public ExportExcelSeedBack(String title,String[] rowName,List
this.dataList = dataList;
this.rowName = rowName;
this.title = title;
}
/*
* 导出数据
* */
public void export(OutputStream out) throws Exception{
try{
HSSFWorkbook workbook = new HSSFWorkbook(); // 创建工作簿对象
HSSFSheet sheet = workbook.createSheet(title); // 创建工作表
// 产生表格标题行
// HSSFRow rowm = sheet.createRow(0);
// HSSFCell cellTiltle = rowm.createCell(0);
//sheet样式定义【getColumnTopStyle()/getStyle()均为自定义方法 - 在下面 - 可扩展】
HSSFCellStyle columnTopStyle = this.getColumnTopStyle(workbook);//获取列头样式对象
HSSFCellStyle style = this.getStyle(workbook); //单元格样式对象
// sheet.addMergedRegion(new CellRangeAddress(0, 1, 0, (rowName.length-1)));//合并单元格
// cellTiltle.setCellStyle(columnTopStyle);
// cellTiltle.setCellValue(title);
// 定义所需列数
int columnNum = rowName.length;
HSSFRow rowRowName = sheet.createRow(0); // 在索引2的位置创建行(最顶端的行开始的第二行)
// 将列头设置到sheet的单元格中
