IREPORT报表实现
一、在JSP中通过传参数实现源代码:(在jasper模板中定义好查询条件及参数)
<% @ page language = " java " import = " java.util.* " pageEncoding = " utf-8 " %>
<% @ page import = " java.io.*,java.sql.*,net.sf.jasperreports.engine.* " %>
<% @ page import = " com.szywit.dbapi.dbconn.CPool,net.sf.jasperreports.engine.data.JRBeanCollectionDataSource,net.sf.jasperreports.engine.util.JRLoader " %>
< jsp:directive.include file = " /public_jdbc.jspf " />
<! DOCTYPE HTML PUBLIC " -//W3C//DTD HTML 4.01//EN " " http://www.w3.org/TR/html4/strict.dtd " >

< body id = " Body " >

String parentid = "" ,sect_name = "" ,actcode = "" ,run_types = "" ;
CommonModel CM;
String reportName = request.getParameter( " reportName " );
if (request.getParameter( " parentid " ) != null )
parentid = request.getParameter( " parentid " );
if (request.getParameter( " pect_name " ) != null )
sect_name = request.getParameter( " pect_name " );
if (request.getParameter( " actcode " ) != null )
actcode = request.getParameter( " actcode " );
if (request.getParameter( " run_types " ) != null )
run_types = request.getParameter( " run_types " );
// 报表编译之后的.jasper文件的存放位置
File reportFile = new File(
application.getRealPath( " /ems/report/eventLog.jasper " ));
// 传递报表中用到的参数值,这里是空值
System.out.println( " param:= " + parentid);
Map parameters = new HashMap();
System.out.print(sect_name);
parameters.put( " event_code " , " % " + event_code + " % " );

try {

}
System.out.println( " ----------jasper begin----------- " );
// 在控制台打印报表文件的物理路径
System.out.println( " ****物理路径 *** " + reportFile.getPath());
byte [] bytes = JasperRunManager.runReportToPdf(
reportFile.getPath(), parameters, conn);
System.out.println( " bytes= " + parameters);
System.out.println( " ---------jasper end------- " );
response.setContentType( " application/pdf " );
response.setContentLength(bytes.length);
// 清除输出对象的冲突(因jsp本身有自己的out输出对象,如果去除下面的语句,则response.getOutputStream()得到的输出对象与原来存在的out对象冲突,会报异常)
out.clear();
out = pageContext.pushBody();
ServletOutputStream output = response.getOutputStream();
output.write(bytes, 0 , bytes.length);
output.flush();
output.close();
try {
if (conn != null) {
