No query executer factory registered for the "MongoDbQuery" language

[kubrauzan]

I want to use my mongo collection and report this. 

But I get this error: Caused by: net.sf.jasperreports.engine.JRRuntimeException: No query executer factory registered for the "MongoDbQuery" language.

My controller:
How can I fix this issue?

 

@GetMapping("/report")
public byte[] generateReport() throws Exception {
    try{
        List<AssignmentDTO> assignmentDTOList= assignmentService.findAll();
        Map<String, Object> params= new HashMap<String, Object>();
        params.put("CompanyName", "Uzan");
        params.put("AssignmentList", new JRBeanCollectionDataSource(assignmentDTOList));

        JasperPrint jasperPrint= JasperFillManager.fillReport(JasperCompileManager.compileReport(ResourceUtils
                .getFile("classpath:books_count_pie.jrxml").getAbsolutePath()), params, new JREmptyDataSource());

        return new ResponseEntity<byte[]>(JasperExportManager.exportReportToPdf(jasperPrint), null, HttpStatus.OK).getBody();
    }
    catch (Exception e){
        return new ResponseEntity<byte[]>(HttpStatus.INTERNAL_SERVER_ERROR).getBody();
    }
}
