我的表格視圖無法顯示數據。它在控制檯中顯示結果集數據，但無法在tableview javafx中顯示。請幫忙。javafx Tableview不顯示數據庫中的數據

類DBConnection的

con = DriverManager.getConnection(db_url, username, password);
} catch (Exception e){
}
return con;
}
public Connection geConnection(){
try {

con = DriverManager.getConnection(db_url+"hotel"+unicode, username, password);
} catch (ClassNotFoundException | SQLException ex) {
System.out.println("Too Many Connection");
}
return con;
}
}
什麼是'Dbconnection'？ –
