what parameter did you add and where did you add it, provide as much detail as you can please
public void crearRuta(Long id) throws FileNotFoundException {
String carpetaRelativa = "Boletin/Curso/";
String rutaCarpeta = carpetaRelativa +
cursoRepositorio.findById(id).get().getCurso() + "" +
cursoRepositorio.findById(id).get().getDivision() + "" +
reemplazarEspacios(cursoRepositorio.findById(id).get().getOrientacion()) + "_" +
cursoRepositorio.findById(id).get().getTurno();
String rutaAbsoluta = servletContext.getRealPath(rutaCarpeta);
crearCarpeta(rutaAbsoluta);
}.
This is the controller that creates the path for the folder where I want the pdf reports to be saved (if it's not already created)
public void crearCarpeta(String ruta) {
File carpeta = new File(ruta);
if (!carpeta.exists()) {
if (carpeta.mkdirs()) {
System.out.println("Carpeta creada correctamente en: " + carpeta.getAbsolutePath());
} else {
System.out.println("Error al crear la carpeta.");
}
} else {
System.out.println("La carpeta ya existe en: " + carpeta.getAbsolutePath());
}
}. This is the function that receives the url and creates the folder if everything goes well
@PostMapping("/export-pdf")
public String exportPdf(@RequestParam("cursoId") Long cursoId, @RequestParam("alumnoIds") List<Long> alumnoIds) throws JRException, FileNotFoundException, SQLException {
crearRuta(cursoId);
for (Long a : alumnoIds) {
Connection connection = null; // Declarar la conexión fuera del bloque try-catch
try {
connection = dataSource.getConnection();
Map<String, Object> params = new HashMap<>();
params.put("p_ciclo_lectivo", 2023);
params.put("p_curso", cursoId.intValue());
params.put("palumno", a.intValue());
String reportName = servletContext.getRealPath("/resources/BoletinCalificaciones.jrxml");
String carpetaRelativa = "Boletin/Curso/";
String rutaCarpeta = carpetaRelativa + cursoRepositorio.findById(cursoId).get().getCurso() + "" +
cursoRepositorio.findById(cursoId).get().getDivision() + "" +
reemplazarEspacios(cursoRepositorio.findById(cursoId).get().getOrientacion()) + "" +
cursoRepositorio.findById(cursoId).get().getTurno() +
"/bol_" + alumnoRepositorio.findById(a).get().getDni() + ".pdf";
String rutaAbsoluta = servletContext.getRealPath(rutaCarpeta);
BoletinReportGenerator.exportToPdf(connection, reportName, rutaAbsoluta, params);
} catch (SQLException e) {
System.out.println(e.getMessage());
} finally {
if (connection != null) {
try {
connection.close();
} catch (SQLException e) {
System.out.println("Error al cerrar la conexión: " + e.getMessage());
}
}
}
}
return "redirect:/boletin/curso-boletin?id=" + cursoId;
}.
Finally this is the controller that creates the pdf files in the url.
that's a lot of Spanish? that I can't read lol
I also can't read java, so that probably doesn't help either
sorry xd, I'm Argentinean
