一、在数据库里面存了一份wps文档
String fgbh = request.getParameter("fgbh");
DynaBean bean = this.queryByFgbh(fgbh);
File file = new File(getSaveBasePath()+File.separator+BeanUtils.getString(bean,"WJMC"));
//设置文件头
//response.setContentType("application/msword;charset=UTF-8");
response.setContentType("application/octet-stream;charset=UTF-8");
response.setHeader("Content-Disposition","attachment;filename="+new String(BeanUtils.getString(bean,"FGMC").getBytes("GBK"),"ISO8859-1")+""");
//提取数据库中的文件
ServletOutputStream sout = response.getOutputStream();
FileUtils.putFileToStream(file.getAbsolutePath(),sout);
sout.flush();
sout.close();
out.clear();
out=pageContext.pushBody();
你可以试试这段代码...
二、用java将数据导出到wps表格中
一:页面图片显示预览：
1）如下图：
2）点击导出按钮后预览：
3）最终生成的excel表格图片预览：
二：代码演示：
说明：执行操作时，请先引进导出excel表格的jar文件包。
找到导出按钮所执行的js方法，在java后天查看该方法的实现即可。
1）jsp代码：
[html] view plaincopyprint?
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<link href="jsp/commonstyle/css/tabStyle.css" rel="stylesheet" type="text/css">
<link rel="STYLESHEET" type="text/css" href="<%=basePath%>jsp/hgltj/js/tablesort.css">
|
| ||||||||||||||||||||
2）java代码演示：
[java] view plaincopyprint?
/**
* 驾校合格率导出excel图表
*/
//response.getOutputStream();// 取得输出流
response.reset();// 清空输出流
String tmptitle = "驾校合格率排名"; // 标题
response.setHeader("Content-disposition", "attachment; filename="+new String(tmptitle.getBytes(),"iso8859-1")+".xls");// 设定输出文件头
response.setContentType("application/vnd.ms-excel");// 定义输出类型
wbook = Workbook.createWorkbook(os); // 建立excel文件
WritableSheet wsheet = wbook.createSheet(tmptitle, 0); // sheet名称
// 设置excel标题
//cellFormat.setBackground(Colour.AQUA);
cellFormat.setFont(wfont);
label.setCellFormat(cellFormat);
wsheet.addCell(label);
//wsheet.addCell(new Label(0, 0, tmptitle, wcfFC));
wsheet.setRowView(0,500); //第一行高度
wsheet.mergeCells(0, 0, 6, 1); //合并单元格(第一列的第一行和第七列的第二行合并)
//wsheet.mergeCells(0, 1, 9, 1);
// wsheet.mergeCells(0, 2, 0, 4);
// wsheet.mergeCells(1, 2, 3, 2);
// wsheet.mergeCells(4, 2, 6, 2);
// wsheet.mergeCells(7, 2, 9, 2);
wsheet.setColumnView(0,10); //宽度
wsheet.setColumnView(1,25); //宽度
wsheet.setColumnView(2,10); //宽度
wsheet.setColumnView(3,10); //宽度
wsheet.setColumnView(4,10); //宽度
wsheet.setColumnView(5,10); //宽度
// 开始生成主体内容
wfont = new jxl.write.WritableFont(WritableFont.ARIAL, 14,WritableFont.BOLD,false, UnderlineStyle.NO_UNDERLINE,Colour.BLACK);
wcfFC = new WritableCellFormat(wfont);
wsheet.addCell(new Label(0, 2, "名次",wcfFC));
wsheet.addCell(new Label(1, 2, "驾校名称",wcfFC));
wsheet.addCell(new Label(2, 2, "科目一",wcfFC));
wsheet.addCell(new Label(3, 2, "科目二",wcfFC));
wsheet.addCell(new Label(4, 2, "科目三",wcfFC));
wsheet.addCell(new Label(5, 2, "合格率",wcfFC));
int count=jxhelpmList.size();
if(count>0){ ////判断集合是否不为0
TjJxkshgl tjhgl=null;
for(int i=0;i
tjhgl=(TjJxkshgl)jxhelpmList.get(i);
wsheet.addCell(new Label(0, i+3, (i+1)+""));
wsheet.addCell(new Label(1, i+3, tjhgl.getJxmc()));
wsheet.addCell(new Label(2, i+3, tjhgl.getKm1hgl()));
wsheet.addCell(new Label(3, i+3, tjhgl.getKm2hgl()));
wsheet.addCell(new Label(4, i+3, tjhgl.getKm3hgl()));
wsheet.addCell(new Label(5, i+3, tjhgl.getAvghgl()));
}
