前言界面以及功能实现
前言
本篇文章主要讲java的GUI技术搭建页面和java的时间驱动来监听操作，jsoup分析网页数据，以及用到fastjson来进行json数据交互。 项目结构如下： 文章很长，虚耐心阅读。 1.首先搭建界面 ** * @Author: lideng_sinosoft * @Date: 2020/10/6 16:40 * @Description: 主窗体 */ @SuppressWarnings("all") public class Main extends JFrame implements ActionListener { //应用，取消，退出等按钮 private JButton apply,cancel,exit; //顶部和底部标签 private JLabel top,buttom; //类别，清晰度，时间间隔，页面等选择框 private JComboBox type,standardOrHd,timer,pager; //统一字体 private Font font = new Font("宋体",Font.BOLD,16); //当前页 private int currentPage = 1; //总页数 private int totalPage = 0; //创建定时器 Timer timerTask = new Timer(); public static void main(String[] args) { //main方法用来启动整个程序 new Main(); } /** 这个方法主要是用来启动加载页面一些数据的 */ public void init(){ String typeValue = (String) type.getSelectedItem(); String hdSelectedItem = (String) standardOrHd.getSelectedItem(); JSONArray types = JsonUtil.getTypes(); for(Object object :types){ JSONObject jsonObject = (JSONObject) object; if (typeValue.equals(jsonObject.getString(Contant.NAME))){ String url = jsonObject.getString(Contant.URL); String hd = ENUM_PAGE_TYPE.HD.getName().equals(hdSelectedItem) ? ENUM_PAGE_TYPE.HD.getValue() : ENUM_PAGE_TYPE.STANDARD.getValue(); Map apply = DownWallPagerUtil.apply(url, hd); totalPage = Integer.valueOf(apply.get(Contant.TOTAL_PAGE)); currentPage = Integer.valueOf(apply.get(Contant.CURRENT_PAGE));
