iReport生成pdf打印

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;
    }
