My stack
Spring boot 1.5.6
JasperReport
Ajax JQuery 3.1.1
My goal
I'm trying to print for first time a report using jasper report, I have a printing service where I have my reports stored, my idea was to send http request via ajax containing data and get a pdf report
What I tried
I have a rest controller in my spring-boot backend which is implemented like this
@RestController
@RequestMapping(PrintController.API)
public class PrintController {
public static final String API="print";
@PostMapping("client")
public void export(@RequestBody List<ClientJsonDto> datas,HttpServletResponse response){
System.out.println(datas);
JRBeanCollectionDataSource itemsJRBean = new JRBeanCollectionDataSource(datas);
/* Map to hold Jasper report Parameters */
Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("ItemDataSource", itemsJRBean);
byte[] bytes = generatePDFReport("refclient", parameters);
return ResponseEntity
.ok()
// Specify content type as PDF
.header("Content-Type", "application/pdf; charset=UTF-8")
// Tell browser to display PDF if it can
.header("Content-Disposition", "attachment;inline; filename=\"client.pdf\"")
.body(bytes);
}
public byte[] generatePDFReport(String inputFileName, Map<String, Object> params) {
return generatePDFReport(inputFileName, params, new JREmptyDataSource());
}
public File loadJasperFile(String file) {
try {
return ResourceUtils.getFile("classpath:static/reports/"+file+".jasper");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
};
return null;
}
public byte[] generatePDFReport(String inputFileName, Map<String, Object> params,
JRDataSource dataSource) {
byte[] bytes = null;
JasperReport jasperReport = null;
try (ByteArrayOutputStream byteArray = new ByteArrayOutputStream()) {
// Check if a compiled report exists
jasperReport = (JasperReport) JRLoader.loadObject(loadJasperFile(inputFileName));
// Compile report from source and save
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, dataSource);
// return the PDF in bytes
bytes = JasperExportManager.exportReportToPdf(jasperPrint);
}
catch (JRException | IOException e) {
e.printStackTrace();
}
return bytes;
}
}
my report is as below

as you see I'm using a parameters where I send a jrcollection, this is used in a tutorial that I found on YouTube.
for the response handling I have this js ajax call
$(document).on('click', '#menu0-func1-menu0-func1', function(){
console.log(printData);
var jsonData =JSON.parse(JSON.stringify(printData));
var settings = {
"async" : true,
"crossDomain" : true,
"url" : "http://"+document.location.host+"/facturation/print/client",
"method" : "POST",
"headers" : {
"cache-control" : "no-cache",
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
"processData" : false,
"contentType" : "application/json",
"dataType" : "text",
"data" : JSON.stringify(printData)
}
$.ajax(settings).done(function(response, status, xhr) {
console.log(response);
// check for a filename
var filename = "";
var disposition = xhr.getResponseHeader('Content-Disposition');
if (disposition && disposition.indexOf('attachment') !== -1) {
var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
var matches = filenameRegex.exec(disposition);
if (matches != null && matches[1]) filename = matches[1].replace(/['"]/g, '');
}
var type = xhr.getResponseHeader('Content-Type');
var blob = new Blob([response], { type: type });
if (typeof window.navigator.msSaveBlob !== 'undefined') {
// IE workaround for "HTML7007: One or more blob URLs were revoked by closing the blob for which they were created. These URLs will no longer resolve as the data backing the URL has been freed."
window.navigator.msSaveBlob(blob, filename);
} else {
var URL = window.URL || window.webkitURL;
var downloadUrl = URL.createObjectURL(blob);
if (filename) {
// use HTML5 a[download] attribute to specify filename
var a = document.createElement("a");
// safari doesn't support this yet
if (typeof a.download === 'undefined') {
window.location = downloadUrl;
} else {
a.href = downloadUrl;
a.download = filename;
document.body.appendChild(a);
a.click();
}
} else {
window.location = downloadUrl;
}
setTimeout(function () { URL.revokeObjectURL(downloadUrl); }, 100); // cleanup
}
});
});
there is no exception, Normally I should at least get the title of the report but I m getting an empty pdf page
here is my console log in Chrome

What to do, I tried lot of tutorials this 3 last days but no success
edit
I generated the pdf using JasperExportManager.exportReportToPdfFile(jasperPrint, "rapport.pdf"); and the pdf file is well formed that is there, I compared the txt representation of this well pdf with the received log, they are the same, my empty pdf is 3kb and the well formed is also 3kb.
I have tried your javascript code and there's an issue indeed.
But the issue comes from within jQuery's ajax implementation. It does not properly handle the response data type.
This post here presents two alternatives: either use the XMLHttpRequest object directly or use a custom jQuery plugin designed specifically for this issue.
Another option could be to split your controller logic in two parts:
