iReport 後端餵資料程式(參考)

String id=request.getParameter("id");

String hql = "from Users as users where 1=1";

hql=hql+String.format(" and ID=%d", Integer.parseInt(id));

UsersDao dao = new UsersDao();

List<Users> users = (ArrayList<Users>) dao.query(hql);

JRDataSource ds = new JRBeanCollectionDataSource(users);

String sourceFileName = new File(this.getServletContext().getRealPath(

"/Report/UsersReport.jasper")).getPath();

System.out.println(sourceFileName);

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

JasperPrint jasperPrint = JasperFillManager.fillReport(

sourceFileName, params, ds);

ServletOutputStream servletOutputStream=response.getOutputStream();

JRPdfExporter exporter=new JRPdfExporter();

exporter.setParameter(JRPdfExporterParameter.JASPER_PRINT,jasperPrint);

exporter.setParameter(JRPdfExporterParameter.OUTPUT_STREAM,servletOutputStream);

//response.setHeader("Content-Disposition","attachment;filename=users.pdf");

response.setHeader("Content-Disposition","inline");

response.setContentType("application/pdf");

exporter.exportReport();
