java reflect 小例子

public static void main(String[] args) {

        Ticket ticket = new Ticket();

        ticket.setAddress("address00");

        ticket.setCity("city00");

        ticket.setPhone("phone00");

        ticket.setPoil("poi00");

        ticket.setTitle("title00");

        Field[] fields = ticket.getClass().getDeclaredFields();

        for (Field field : fields) {

            field.setAccessible(true);//这行是必须的

            try {

                System.out.println(field.get(ticket).toString());

            } catch (IllegalArgumentException e) {

                e.printStackTrace();

            } catch (IllegalAccessException e) {

                e.printStackTrace();

            }

        }

    }
