Question

我想将.dat文件转换为人类可读的.txt文件，然后应将其插入数据库中。我尝试转换.dat文件，但到目前为止没有成功。

示例：

[original .dat file][1]

输出应如下所示：

612，*，Familienpension Sonnenhof，Fesser Noana，Panhans Anna-Irina，Sonnenwg 3，Lackenhof，3295，7728963，4，18

SQL类如下：

public static void addMasterData() {
        //ObservableList Klasse damit der DatenbankListener darauf Veraenderungen registriert
        ObservableList<Hotel> hotelsData = null;
        try {
            Statement st = Main.connection.createStatement();
            hotelsData = FXCollections.observableArrayList(); // Hier auch Observable fuer Datenbanklistener
            //Set in der die Abfrageergebnisse der Tabelle gespeichert werden
            ResultSet rs = st.executeQuery("SELECT * FROM hotel");
            // 4. Process the ResultSet by scrolling the cursor forward via next().
            while (rs.next()) {
                Hotel hotel = new Hotel(
                        rs.getInt(1),
                        rs.getString(3),
                        rs.getString(2),
                        rs.getString(4),
                        rs.getString(5),
                        rs.getString(6),
                        rs.getString(7),
                        rs.getString(8),
                        rs.getString(9),
                        rs.getInt(10),
                        rs.getInt(11)
                );
                hotelsData.add(hotel);
            }
        } catch (SQLException ex) {
            // 5. Connection und Statement schließen, automatisch mit try-with-resources (JDK 7)
            JOptionPane.showMessageDialog(null, ex);        
        }
        try {
            //Hotel in the hotel Tabelle einfuegen
            String query = "insert into hotel ("
                    + "hotel_id, "
                    + "name, "
                    + "category, "
                    + "owner, "
                    + "contact, "
                    + "address, "
                    + "city, "
                    + "city_code, "
                    + "phone, "
                    + "rooms, "
                    + "beds)"
                    + " values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";

            File file = new File("src/touristoffice/ui/hotel.txt");
            BufferedReader br = new BufferedReader(new FileReader(file));
            String line = "";
            // Ursprungsdatei Einlesen
            while ((line = br.readLine()) != null) { //solange Datenbankeinträge vorhanden sind
                String data[] = line.split(",");
                Statement statement = Main.connection.createStatement();

                PreparedStatement preparedStmt = Main.connection.prepareStatement(query);
                preparedStmt.setInt(1, Integer.parseInt(data[0]));
                preparedStmt.setString(2, data[2]);
                preparedStmt.setString(3, data[1]);
                preparedStmt.setString(4, data[3]);
                preparedStmt.setString(5, data[4]);
                preparedStmt.setString(6, data[5]);
                preparedStmt.setString(7, data[6]);
                preparedStmt.setString(8, data[7]);
                preparedStmt.setString(9, data[8]);
                preparedStmt.setInt(10, Integer.parseInt(data[9]));
                preparedStmt.setInt(11, Integer.parseInt(data[10]));

                // preparedstatement ausführen
                preparedStmt.execute();


            }````

If you have an idea, please let me know, thanks!
