首先下载jxl-2.6.12.jar或者在maven中添加
<dependency> <groupId>net.sourceforge.jexcelapi</groupId> <artifactId>jxl</artifactId> <version>2.6.12</version> </dependency>
后台代码如下：
WritableWorkbook wwb = null;
wwb=Workbook.createWorkbook(new File("c:\\1.xls"));//创建excel文件
WritableSheet ws = wwb.createSheet("sheet1", 0);//创建一个可写入的工作表
ws.setColumnView(0,25);
ws.setColumnView(6,20);
ws.setColumnView(9,20);
ws.setColumnView(11,30);//设置列的宽度
//设置表头
ws.addCell(new Label(0,0,"商品图片"));
ws.addCell(new Label(1,0,"商品名称"));
ws.addCell(new Label(2,0,"市场价格"));
ws.addCell(new Label(3,0,"会员价格"));
ws.addCell(new Label(4,0,"被测人"));
ws.addCell(new Label(5,0,"状态"));
ws.addCell(new Label(6,0,"收样品时间"));
ws.addCell(new Label(7,0,"收件人"));
ws.addCell(new Label(8,0,"物流单号"));
ws.addCell(new Label(9,0,"发报告时间"));
ws.addCell(new Label(10,0,"物流单号"));
ws.addCell(new Label(11,0,"检测报告"));
//添加行数据，遍历需要写入excel的集合数据
for (int i=1;i<=odvs.size();i++){
OrderDetailVo row=odvs.get(i-1);
System.out.println(row);
ws.addCell(new Label(0,i,row.getThumbNail()));
ws.addCell(new Label(1,i,row.getName()));
ws.addCell(new Label(2,i,row.getMarketPrice().toString()));
ws.addCell(new Label(3,i,row.getMemberPrice().toString()));
ws.addCell(new Label(4,i,row.getPersonName()));
ws.addCell(new Label(5,i,row.getStatus()));
ws.addCell(new Label(6,i,row.getRecieveOrderDate().toString()));
ws.addCell(new Label(7,i,row.getContact()));
ws.addCell(new Label(8,i,row.getReceiveTrackNumber()));
ws.addCell(new Label(9,i,row.getReportSendDate().toString()));
ws.addCell(new Label(10,i,row.getReportTrackNumber()));
ws.addCell(new Label(11,i,row.getReportDownloadPath()));
}
wwb.write();//从内存中写入文件中
wwb.close(); //关闭资源，释放内存
