Web sayfamda pdfüm görüntülenemiyorUygulama (engelleme modunda değil)

Question

HI Sorunum, Spring mvc ve açısal js arasında. Bir pdf'yi yayma isteği aldım. Url, tek başıma test ettiğim için gayet iyi çalışıyor. Ancak sorun, FrontEnd ile etkileşimde bulunduğumda ve engelleme modunda değil, istisnayı alıyorum. İşte benim kodudur:

@RequestMapping(value = "/getFacture", method = RequestMethod.GET, headers = "Accept=application/json") 
    public @ResponseBody OutputStream postPrice(HttpServletResponse response) throws IOException { 

     try { 
      JasperTest.main(response.getOutputStream()); 
      response.setContentType("application/pdf"); 
     } catch (IOException e) { 

      e.printStackTrace(); 
     } 
     return JasperTest.main(response.getOutputStream()); 


    } 

JasperTest.java

public static OutputStream main(OutputStream out) { 

     try { 
      System.out.println("Generating PDF..."); 

      JasperReport jasperReport = JasperCompileManager 
        .compileReport(JasperTest.class.getClassLoader().getResource("hellojasper.jrxml").getPath()); 


      List<ParamJasper> l = new ArrayList<ParamJasper>(); 

      l.add(new ParamJasper("Card 12")); 
      JRDataSource JRdataSource = new JRBeanCollectionDataSource(l); 
      JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, 
        JRdataSource); 
      JasperExportManager.exportReportToPdfStream(jasperPrint, out); 

      System.out.println("HelloJasper.pdf has been generated!"); 
     } catch (JRException e) { 
      e.printStackTrace(); 
     } 
     return out; 

    } 

Benim ön uç Kodu: Denetleyici:

$scope.continueCheckOut = function(total, priceByCard, priceByCheque, 
      priceByEspece, size) { 
     $scope.priceByCard = priceByCard; 
     $scope.priceByCheque = priceByCheque; 
     $scope.priceByEspece = priceByEspece; 

     $scope.cancel(); 
     $scope.total = total; 
     ProductService.postPayement($scope.priceByCard, $scope.priceByEspece, 
       $scope.priceByCheque, $scope.total,$rootScope.test.idClient).then(function(d) { 

      self.payment = d; 
      if (self.payment.result == true) 
{ 
       console.log("Felecitation"); 
       ProductService.getFacture().then(function(d) { 

        self.pdf = d; 
       }, function(errResponse) { 
        console.error('Error while generating pdf'); 
       }); 
} 
      if (self.payment.result == false) { 
       if (self.payment.reste != 0) { 
        $scope.reste = self.payment.reste; 
        console.log("scope reste is " + -($scope.reste)); 
       } else 
        alert("Veuillez payer le montant souhaité"); 
      } 

     }, function(errResponse) { 
      console.error('Error while fetching Currencies'); 
     }); 



    }; 

myFrontEnd Hizmeti:

getFacture : function() 
    { 
     return $http.get('http://127.0.0.1:9001/PrototypePos/rest/products/getFacture') 
    .then(
       function(response){ 
        return response.data; 
       }, 
       function(errResponse){ 
        console.error('Error while genrating facture'); 
        return $q.reject(errResponse); 
       } 
     ); 
    }
