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" />

<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

           parameters.put(

           parameters.put(

           parameters.put(

        Connection conn = null;
        
try {
            conn

        }
 catch (Exception e) {
            e.printStackTrace();
            
throw new Exception("创建默认数据库连接不成功,请检查dbconn.properties是否正确配置");
        }

        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(

        out

        ServletOutputStream output

        output.write(bytes,
