3.导出HTML格式报表

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.jsp.JspWriter;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperPrint;

     }
    }
   }
  
  } catch (IOException ioe) {
   ioe.printStackTrace();
  }
  throw new Exception("使用JRHtmlExporter导出Html格式时发生错误！");
}

4.导出Pdf报表

import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.ServletOutputStream;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRExporterParameter;

*/
public class PDFExport {

public void exportToPDF(HttpServletRequest request,HttpServletResponse response,String jrxmlFilePath,String reportFilePath,Map params,JRDataSource dataSource) throws Exception
{
    try{
          response.reset();

          response.setContentType("application/pdf;charset=GBK");
           //PDF导出路径及名称
String destFileName = reportFilePath.substring(0,reportFilePath.lastIndexOf(".")) + ".pdf";

//导出PDF方法一
//JasperExportManager.exportReportToPdfFile(jasperPrint, destFileName);

//导出PDF方法二
//得到jasperPrint对象
JasperPrint jasperPrint=new JasperPrintWithJRDataSource(jrxmlFilePath,reportFilePath,params,dataSource).getJasperPrint();
JRPdfExporter pdfexporter = new JRPdfExporter();
pdfexporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
pdfexporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, destFileName);
pdfexporter.exportReport();      System.out.println("Done!");
}catch(IOException e){
  e.printStackTrace();
    }

}
}

5.导出RTF报表

import java.io.IOException;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.jsp.JspWriter;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.export.JRRtfExporter;

/**
* @类名：RTFExport.java
* @类功能描述:导出RTF报表
* @author lbc
* @version v1.0.0.1
* @see
*/
public class RTFExport {

public void exportToRtf(HttpServletRequest request,HttpServletResponse response,String jrxmlFilePath,String reportFilePath,Map params,JRDataSource dataSource) throws Exception {
 
  try {
   JasperPrint jasperPrint=new JasperPrintWithJRDataSourceNew(jrxmlFilePath,reportFilePath,params,dataSource).getJasperPrint();
   JRRtfExporter rtfExporter=new JRRtfExporter();
   rtfExporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
   //设置导出文件名
   rtfExporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "c://myrtf.rtf");
   rtfExporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "GB2312");
   rtfExporter.exportReport();
   System.out.println("Done!");
  } catch (IOException e) {
   e.printStackTrace();
  }
}

}

6.导出XML报表

import java.io.IOException;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.export.JRXmlExporter;

/**
* @类名：XMLExport.java
* @类功能描述: 导出XML报表
* @author lbc

* @version v1.0.0.1
* @see
*/
public class XMLExport {

public void exportToXml(HttpServletRequest request,HttpServletResponse response,String jrxmlFilePath,String reportFilePath,Map params,JRDataSource dataSource) throws Exception  {
 
  try {
   JasperPrint jasperPrint=new JasperPrintWithJRDataSourceNew(jrxmlFilePath,reportFilePath,params,dataSource).getJasperPrint();
   JRXmlExporter xmlExporter=new JRXmlExporter();
   xmlExporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
   xmlExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, response.getOutputStream());
   xmlExporter.exportReport();
   response.setContentType("text/xml");
   System.out.println("Done!");
  } catch (IOException e) {
   e.printStackTrace();
  }
}

}

由于在浏览器中打开Xml时，在页面设置里需进行内容类型的设置，因此最好在JSP页面中加上如下代码：

<%@ page contentType="text/xml;charset=GBK"%>

7.导出Excel报表

import java.io.IOException;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.export.JRXlsExporter;
import net.sf.jasperreports.engine.export.JRXlsExporterParameter;

/**
* @类名：EXCELExport.java
* @类功能描述: 导出Excel报表
* @author lbc
* @version v1.0.0.1
* @see
*/
public class EXCELExport {

public void exportToExcel(HttpServletRequest request,HttpServletResponse response,String jrxmlFilePath,String reportFilePath,Map params,JRDataSource dataSource) throws Exception {
 
  try {

   response.reset();
   response.setContentType("application/vnd.ms-excel;charset=GBK");
   JasperPrint jasperPrint=new JasperPrintWithJRDataSourceNew(jrxmlFilePath,reportFilePath,params,dataSource).getJasperPrint();
   JRXlsExporter jrXlsExporter=new JRXlsExporter();
   jrXlsExporter.setParameter(JRExporterParameter.JASPER_PRINT,jasperPrint);
   //设置输出流
   jrXlsExporter.setParameter(JRExporterParameter.OUTPUT_STREAM,response.getOutputStream());
   jrXlsExporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET,Boolean.FALSE);
   jrXlsExporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "GB2312");
   jrXlsExporter.exportReport();

   System.out.println("Done!");
  } catch (IOException e) {
   e.printStackTrace();
  }
}

}

由于在浏览器中打开Excel时，在页面设置里需进行内容类型的设置，因此最好在JSP页面中加上如下代码：

<%@ page contentType="application/vnd.ms-excel;charset=GBK"%>

8.ACTION调用，导出报表

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import lbc.report.report.EXCELExport;
import lbc.report.report.HTMLExportNew;
import lbc.report.report.PDFExport;
import lbc.report.report.RTFExport;
import lbc.report.report.ReportDataSource;
import lbc.report.report.XMLExport;

import net.sf.jasperreports.engine.JRDataSource;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;


/**
* @类名：jycfjdsAction.java
* @类功能描述: ACTION调用，导出报表
* @author lbc
* @version v1.0.0.1
* @see
*/
public class jycfjdsAction extends DispatchAction {

public ActionForward loadReport(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) throws Exception {

  Map params = new HashMap();
  JRDataSource dataSource = new ReportDataSource();
  //导出HTML报表
  HTMLExportNew htmExportNew=new HTMLExportNew();
  htmExportNew.export(request,response,request.getRealPath("/report/jycfjds.jrxml"), request.getRealPath("/report/jycfjds.jasper"), params, dataSource);
  //导出PDF报表
  //PDFExport pdfExport=new PDFExport();
  //pdfExport.exportToPDF(request, response, request.getRealPath("/report/jycfjds.jrxml"),request.getRealPath("/report/jycfjds.jasper"), params, dataSource);
        //导出EXCEL报表
  //EXCELExport excelExport=new EXCELExport();
  //excelExport.exportToExcel(request, response, request.getRealPath("/report/jycfjds.jrxml"), request.getRealPath("/report/jycfjds.jasper"), params, dataSource);
  //导出XML报表
  //XMLExport xmlExport=new XMLExport();
  //xmlExport.exportToXml(request, response, request.getRealPath("/report/jycfjds.jrxml"), request.getRealPath("/report/jycfjds.jasper"), params, dataSource);
  //导出RTF报表
  //RTFExport rtfExport=new RTFExport();
  //rtfExport.exportToRtf(request, response,request.getRealPath("/report/jycfjds.jrxml"), request.getRealPath("/report/jycfjds.jasper"), params, dataSource);
 
  return null;
}
}

9.调用JSP页面导出报表

<%@ page language="java" contentType="text/html; charset=GBK" pageEncoding="GBK"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<%@page import="lbc.report.report.PDFExport"%>
<%@page import="net.sf.jasperreports.engine.JRDataSource"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<body>
<%
//设置JRDataSource连接
JRDataSource dataSource=new ReportDataSource();
//设置外部参数对
Map parameters=new HashMap();
parameters.put("rptToday","2009-06-04");
parameters.put("rptMan","lbc");

PDFExport pdfExport=new PDFExport();
pdfExport.exportToPDF(request,response,request.getRealPath("/reports/jycfjds.jrxml"),request.getRealPath("/reports/jycfjds.jasper"),parameters,dataSource);

%>
</body>
</html>
