jasperreport生成html,Excel,PDF报表�Q�数据源使用List

robbin163 — Sun, 12 Nov 2006 14:21:00 GMT

jasperreport中可以��用List作�ؓ数据源，使用格式如下.
List list=this.customerDao.getAllCustomer(); //得到所有客�?br />JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
   JasperPrint jasperPrint = JasperFillManager.fillReport(
     reportFilePath, parameters, ds);
得填充数据后�Q�即可输出显�C�到PDF,Excel,Html
到PDF:
public byte[] generatePDF(String begCustNo, String endCustNo,
   String reportTitle, String reportFilePath) throws DemoException {
  // TODO Auto-generated method stub
//begCustNo,endCustNo分别为查询传入的开始编��P��l�束�~�号.
  jdbcCustomerDao = new JdbcCustomerDao();
  Map parameters = new HashMap();
  parameters.put("ReportTitle", reportTitle);//报表标题
  List list = jdbcCustomerDao.getAllCustomer(begCustNo, endCustNo);
   try {
   JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
   JasperPrint jasperPrint = JasperFillManager.fillReport(
     reportFilePath, parameters, ds);   return JasperExportManager.exportReportToPdf(jasperPrint);
  } catch (JRException e) {
   throw new DemoException("Report Export Failed.");
  }
}
到Html:
public byte[] generateHtml(String begCustNo, String endCustNo,
   String reportTitle, String reportFilePath) throws DemoException {
  jdbcCustomerDao = new JdbcCustomerDao();
  Map parameters = new HashMap();
  parameters.put("ReportTitle", reportTitle);
  List list = jdbcCustomerDao.getAllCustomer(begCustNo, endCustNo);
  System.out.println("list size is :" + list.size());
  JRHtmlExporter exporter = new JRHtmlExporter();
  ByteArrayOutputStream oStream = new ByteArrayOutputStream();
  try {
   JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
   JasperPrint jasperPrint = JasperFillManager.fillReport(
     reportFilePath, parameters, ds);
   exporter.setParameter(
     JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN,
     Boolean.FALSE);
   exporter
     .setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
   exporter
     .setParameter(JRExporterParameter.CHARACTER_ENCODING, "GBK");
   exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, oStream);
   exporter.exportReport();
   byte[] bytes = oStream.toByteArray();
   return bytes;
  } catch (JRException e) {
   throw new DemoException("Report Export Failed.");
  }
}
到Excel:
public byte[] generateExcel(String begCustNo, String endCustNo,
   String reportTitle, String reportFilePath) throws DemoException {
  jdbcCustomerDao = new JdbcCustomerDao();
  Map parameters = new HashMap();
  parameters.put("ReportTitle", reportTitle);
  List list = jdbcCustomerDao.getAllCustomer(begCustNo, endCustNo);
  System.out.println("list size is :" + list.size());
  JRXlsExporter exporter = new JRXlsExporter(); // Excel
  ByteArrayOutputStream oStream = new ByteArrayOutputStream();
  try {
   JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
   JasperPrint jasperPrint = JasperFillManager.fillReport(
     reportFilePath, parameters, ds);
   exporter
     .setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
   exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, oStream);
   exporter.setParameter(
     JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,
     Boolean.TRUE);
   exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET,
     Boolean.FALSE);
   exporter.setParameter(
     JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND,
     Boolean.FALSE);
   exporter.exportReport();
   byte[] bytes = oStream.toByteArray();
   return bytes;

  } catch (JRException e) {
   throw new DemoException("Report Export Failed.");
  }
}
