How to use JasperReports with Spring MVC?

Question

I\'ve been investigating the use of JasperReports (6.0.0) with Spring MVC (4.1.3) to generate PDF reports. Spring is rife with \"Spring specific\" ways to integrate with Jas

My Method:

   @RequestMapping(value="getPDF", method=RequestMethod.GET)
   public void generatePDF(int idPredstave, HttpServletResponse response) throws Exception{

    Predstava p = pr.findById(idPredstave).get();
    List uloge = ur.findByPredstava(p);

    response.setContentType("text/html");
    JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(uloge);
    InputStream inputStream = this.getClass().getResourceAsStream("/jasperreports/Uloge.jrxml");
    JasperReport jasperReport = JasperCompileManager.compileReport(inputStream);
    Map params = new HashMap();
    params.put("nazivPredstave", p.getNaziv());
    params.put("trajanje", p.getTrajanje());
    params.put("opis", p.getOpis());
    params.put("zanr", p.getZanr().getNaziv());
    params.put("reziser", p.getReziser().getIme()+" "+p.getReziser().getPrezime());
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, dataSource);
    inputStream.close();


    response.setContentType("application/x-download");
    response.addHeader("Content-disposition", "attachment; filename=Uloge.pdf");
    OutputStream out = response.getOutputStream();
    JasperExportManager.exportReportToPdfStream(jasperPrint,out);
}
