So speichern und generieren Sie ein PDF aus Textfeldern mit javafx

Question

Ich habe ein Formular erstellt, in dem der Benutzer Felder (Name, Vorname, Nummer, Datum1, Datum2 und wählen zwischen 3 Propositionen: Mann, Frau, Kind) füllt. Ich wünschte, ich könnte Benutzerantworten speichern (um sie in eine Datenbank zu bringen) und sie in eine PDF-Datei integrieren.

Allerdings kann ich nichts funktionales für meine pdf tun, wie es geht? Hast du Ratschläge oder Beispiele? Sollte ich eine PDF-Vorlage erstellen, vor der Feld für Benutzer antworten? Ich habe versucht, etwas mit 'itextpdf' zu tun, aber ohne Erfolg eine andere Strategie?

hilf mir!

hier ist mein Code:

Datendatei

public class Data { 

    private String name; 
    private String surname; 
    private Integer numb; 
    private String date1; 
    private String date2; 

    public Patient(String name, String surname, Integer numb, String date1, String date2) { 
     super(); 
     this.name = name; 
     this.surname = surname; 
     this.numb = numb; 
     this.date1 = date1; 
     this.date2 = date2; 
    } 

    public String getName() { 
     return name; 
    } 

    public String getSurname() { 
     return surname; 
    } 

    public Integer getNumb() { 
     return numb; 
    } 

    public String getDate1() { 
     return date1; 
    } 

    public String getDate2() { 
     return date2; 
    }

Answer 1

Sie können itext Tool für PDF-Dateien zu erzeugen. Sie sollten sich darauf verlassen können. Es gibt viele Beispiele über die Verwendung von Itext-PDF-Tool mit Java-Programmierung.

Sie haben bereits Daten in pdf anzuzeigen, Erstellen Sie einfach eine Klasse namens GeneratePdf und verwenden Sie sie. Sie müssen nur Ihre Daten an iext Absatz, Tabelle, Zelle geben, was Sie brauchen.

Beispiele in here.
