建立一個printByJasperDemo.jsp，程式碼如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page
import="java.io.*,net.sf.jasperreports.engine.*,net.sf.jasperreports.engine.util.*,java.util.*,java.sql.*,net.sf.jasperreports.engine.export.*"%>
<script type="text/javascript">
function printView() {
window.print();
}
</script>
<!-- 實現列印的關鍵樣式,Noprint:使用該樣式的元素在列印時會被忽略;PageNext:瀏覽器列印介面能夠識別的分頁標記,碰到有該樣式的元素,瀏覽器列印介面就知道要換一頁了 -->
<style media="print" type="text/css">
.Noprint {
display: none;
}
.PageNext {
page-break-after: always;
}
</style>
<button onclick="printView()" class="Noprint">列印預覽</button>
<%
File reportFile = new File(
application.getRealPath("jasper/elecPayPrint.jasper"));
JasperReport jasperReport = (JasperReport) JRLoader
.loadObject(reportFile.getPath());
//Map裡面可以封裝jasper中用到的引數
Map parameters = new HashMap();
parameters.put("make_code", "D_20140116_0053");

parameters.put("make_man", "雷巨集");
parameters.put("area_name", "長沙");

Connection conn = DriverManager.getConnection(

JRHtmlExporter exporter = new JRHtmlExporter();
