I have several reports made in Jaspersoft that generate PDF and when generated in Java, when downloading the report on my pc, it is as "Document.pdf". How do I name this report differently, for example "reportario_clients.pdf"? The reports were assembled by Jaspersoft and my application is in Java and spring to call the report do the following:

@GetMapping("/clientes")
public ModelAndView gerarRelatoriosClientes(@AuthenticationPrincipal UsuarioSistema usuarioSistema) throws MalformedURLException, IOException {

    HashMap<String, Object> parametros = new HashMap<String, Object>();

    parametros.put("codigoEmpresa", usuarioSistema.getUsuario().getEmpresa().getCodigo());
    parametros.put("format", "pdf");
    return new ModelAndView("relatorio_clientes", parametros);
}

Can someone help me?

  • Where is the code using jasperReport that you create the PDF?. Post it please

  • Thus, it is a jrxml made in Jaspersoft, it is very extensive for all here, follows the beginning and end of it:

  • In the application has a class called Webconfig, where I have all the cofigurations, the responsible method for detecting japer is this:

  • Jasperreportsviewresolver resolver = new Jasperreportsviewresolver(); resolver.setPrefix("classpath:/reports/"); resolver.setSuffix(".Jasper"); resolver.setViewNames("report_*"); resolver.setViewClass(Jasperreportsmultiformatview.class); resolver.setJdbcDataSource(datasource); resolver.setOrder(0); Return resolve;

Jasperreports has the method JasperExportManager.exportReportToPdfFile(print, "nome_arquivo");.

Where the second argument is the file name. I’ll put an example:

public void relatorioTeste(String parametro) {
    parametros.put("parametro", parametro);
    try {
        JasperReport report = (JasperReport)JRLoader.loadObject(getClass().getResourceAsStream("/jasperteste/RelatorioTeste.jasper"));
        geraRelatorio(report);
    } catch (JRException e) {
        //tratar exceção
    }
}

private void geraRelatorio(JasperReport report) {
    try {
        JasperPrint print = JasperFillManager.fillReport(report, parametros, conexao);
        JasperExportManager.exportReportToPdfFile(print, "nome_arquivo");
        con.close();
    } catch (JRException e) {
        //tratar exceção
    } catch (SQLException e) {
        //tratar exceção
    }
    parametros.clear();
}

Maybe creating the PDF on your system is different, but this can help you.
