下面小编就为大家分享一篇iReport生成pdf打印的实例代码，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

先下载ireport版本，我下载的是 iReport-5.0.4 编辑模板 employees_identity_print_templet

									@RequestMapping("printEmpPdf")

									 @ResponseBody

									 public Result printEmpPdf(HttpServletRequest request,HttpServletResponse response, Parameter parameter){

									 Result result=Result.getInitializedResult();

									 try{

									  parameter = generateParameter(parameter, request);

									  Map<String,Object> map= parameter.getParam();

									  List<EmployeeVO> employeeVOList=employeeBiz.printPdfBarcode(map);

									  // 报表数据源

									  JRDataSource jrDataSource = new JRBeanCollectionDataSource(employeeVOList);

									  //模板地址

									  String jasperSource_adidas= CommonUtils.getAllMessage("jdbc","EMPLOYEES_IDENTITY_PRINT_PDF_TEMPLET")+"employees_identity_print_templet.jasper";

									  File reportFile = new File(jasperSource_adidas);

									  Map<String, Object> param_common=new HashMap<String, Object>();

									  param_common.put("subReport",jasperSource_adidas);

									  JasperPrint jasperPrint;

									  jasperPrint = JasperFillManager.fillReport(reportFile.getPath(), param_common, jrDataSource);

									  String fullPath = String.valueOf(System.currentTimeMillis()).concat("_员工列表.pdf"); //生成PDF文件保存地址

									  String filePdfUrl= CommonUtils.getAllMessage("jdbc","IREPORT_FILE_URL");

									  JRPdfExporter pdfExporter = new JRPdfExporter();

									  ByteArrayOutputStream baos = new ByteArrayOutputStream();

									  pdfExporter.setParameter(JRExporterParameter.JASPER_PRINT,jasperPrint);

									  pdfExporter.setParameter(JRExporterParameter.OUTPUT_STREAM, baos);

									  pdfExporter.exportReport();

									  byte[] bytes = baos.toByteArray();

									  File file=new File(filePdfUrl+fullPath);

									  WebUtil.writeByteArrayToFile(file,bytes);

									  result.baseSucResult(fullPath);

									 }catch (Exception e){

									  result.baseFailResult("EmployeeController printEmpPdf error",parameter);

									  logger.error("EmployeeController printEmpPdf error",e);

									 }

									 return result;

									 }
