一、程序实现

项目目录：

MyJFrame：实现项目界面样式；

AppProcess：实现调用api或爬虫拿数据；

NLIProcess：解析用户输入语句意图；

lib中是程序开发需要用到的jar包列表。

主要代码说明：

程序不同功能领域由选项卡JTabbedPane展示。用户输入哪个功能领域的问题，将由该领域的选项卡展示答案。

在选项卡中添加选项：

tabbedPanel.addTab("笑话",panel_joke); tabbedPanel.addTab("新闻",panel_news); tabbedPanel.addTab("星座",panel_hor); tabbedPanel.addTab("成语",panel_idiom); tabbedPanel.addTab("解梦",panel_oneir);

切换选项卡时给出对应功能领域的语料示例：

tabbedPanel.addChangeListener(new ChangeListener(){ @Override public void stateChanged(ChangeEvent arg0) { // TODO Auto-generated method stub int index = tabbedPanel.getSelectedIndex(); areaTxt.setText(introduce + introduces[index]); ((JScrollPane)tabbedPanel.getComponent(index)).setViewportView(areaTxt); } });

输出答案时切换为对应功能选项卡展示答案：

private void jButton_sendActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: Map<String, Object> retMap = app.process(jTextField1.getText()); jLabel2.setText(""); if (retMap.containsKey("ds")) { jLabel2.setText(retMap.get("ds").toString()); jLabel2.setForeground(Color.red); } else if (retMap.containsKey("joke")) { Object obj = retMap.get("joke"); tabbedPanel.setSelectedIndex(0); JScrollPane jpanel = ((JScrollPane) tabbedPanel.getComponent(0)); if (obj instanceof String) { areaTxt.setText(obj.toString()); jpanel.setViewportView(areaTxt); } else { JLabel jLabel = new JLabel(); if (obj != null) { ImageIcon image = new ImageIcon((URL) obj); jLabel.setIcon(image); } else { jLabel.setText("图片加载失败!"); } jpanel.setViewportView(jLabel);} }else if (retMap.containsKey("horoname")){ Object obj = retMap.get("horoname"); tabbedPanel.setSelectedIndex(2); JScrollPane jpanel = ((JScrollPane) tabbedPanel.getComponent(2)); areaTxt.setText(obj.toString()); jpanel.setViewportView(areaTxt); }else if(retMap.containsKey("news")){ Object obj = retMap.get("news"); tabbedPanel.setSelectedIndex(1); JScrollPane jpanel = ((JScrollPane) tabbedPanel.getComponent(1));if (obj instanceof String) { areaTxt.setText(obj.toString()); jpanel.setViewportView(areaTxt); }else{ @SuppressWarnings("unchecked") Map<String, List<String>> newsMap = (HashMap<String, List<String>>)obj; List<String> titleList = newsMap.get("title"); final List<String> urlList = newsMap.get("url");table = getSimpleTable(titleList); jpanel.setViewportView(table); table.addMouseListener(new MouseListener(){@Override public void mouseClicked(MouseEvent arg0) { // TODO Auto-generated method stub // 取得用户所选行的行数 int selectRows=table.getSelectedRows().length; if(selectRows==1){ // 取得用户所选单行 int selectedRowIndex = table.getSelectedRow(); String url = urlList.get(selectedRowIndex); Desktop desktop = Desktop.getDesktop(); try { desktop.browse(new URI(url)); } catch (IOException | URISyntaxException e1) { e1.printStackTrace(); } }}@Override public void mouseEntered(MouseEvent arg0) {}@Override public void mouseExited(MouseEvent arg0) {}@Override public void mousePressed(MouseEvent arg0) {}@Override public void mouseReleased(MouseEvent arg0) {}});}}else if(retMap.containsKey("oneiromancy")){ Object obj = retMap.get("oneiromancy"); tabbedPanel.setSelectedIndex(4); final JScrollPane jpanel = ((JScrollPane) tabbedPanel.getComponent(4));if (obj instanceof String) { areaTxt.setText(obj.toString()); jpanel.setViewportView(areaTxt); }else{ @SuppressWarnings("unchecked") Map<String, List<String>> OneirMap = (HashMap<String, List<String>>)obj; List<String> wordList = OneirMap.get("word"); final List<String> urlList = OneirMap.get("url"); table = getSimpleTable(wordList); jpanel.setViewportView(table); table.addMouseListener(new MouseListener(){@Override public void mouseClicked(MouseEvent arg0) { // TODO Auto-generated method stub // 取得用户所选行的行数 int selectRows=table.getSelectedRows().length; if(selectRows==1){ // 取得用户所选单行 int selectedRowIndex = table.getSelectedRow(); String url = urlList.get(selectedRowIndex); String answer = app.getOneirData(url); areaTxt.setText(answer); jpanel.setViewportView(areaTxt); }}@Override public void mouseEntered(MouseEvent arg0) {}@Override public void mouseExited(MouseEvent arg0) {}@Override public void mousePressed(MouseEvent arg0) {}@Override public void mouseReleased(MouseEvent arg0) {}});}}else if(retMap.containsKey("idioms")){ Object obj = retMap.get("idioms"); tabbedPanel.setSelectedIndex(3); final JScrollPane jpanel = ((JScrollPane) tabbedPanel.getComponent(3));if (obj instanceof String) { areaTxt.setText(obj.toString()); jpanel.setViewportView(areaTxt); }else{ @SuppressWarnings("unchecked") Map<String, List<String>> OneirMap = (HashMap<String, List<String>>)obj; List<String> nameList = OneirMap.get("name"); final List<String> idList = OneirMap.get("id"); table = getSimpleTable(nameList); jpanel.setViewportView(table); table.addMouseListener(new MouseListener(){@Override public void mouseClicked(MouseEvent arg0) { // TODO Auto-generated method stub // 取得用户所选行的行数 int selectRows=table.getSelectedRows().length; if(selectRows==1){ // 取得用户所选单行 int selectedRowIndex = table.getSelectedRow(); String id = idList.get(selectedRowIndex); String answer = app.getIdiomsP(id); areaTxt.setText(answer); jpanel.setViewportView(areaTxt); }}@Override public void mouseEntered(MouseEvent arg0) {}@Override public void mouseExited(MouseEvent arg0) {}@Override public void mousePressed(MouseEvent arg0) {}@Override public void mouseReleased(MouseEvent arg0) {}});}}}

使用Jsoup解析XML:

private Map<String, List<String>> getNewsMap(String type){ Map<String, List<String>> newsMap = new HashMap<>(); List<String> titleList = new ArrayList<>(); List<String> urlList = new ArrayList<>(); String url = MessageFormat.format("http://www.chinanews.com/rss/{0}.xml", type); String httpContent = getHttpContent(url,"gbk");Document doc = Jsoup.parse(httpContent, "", new Parser(new XmlTreeBuilder())); //item Elements itemElements = doc.select("item"); if(itemElements != null){ for(Element e : itemElements){ String title = e.select("title").first().text(); String link = e.select("link").first().text(); titleList.add(title); urlList.add(link); }newsMap.put("title", titleList); newsMap.put("url", urlList); }return newsMap; }

二、运行效果

运行截图如下：

笑话(支持看笑话、看趣图)：

新闻（显示新闻列表，点选后可进入新闻详情页）：

星座（支持查今日、明日、本周、本月、今年运势）：

成语（支持成语释义、查带某字、词的成语）：

解梦：

三、其他补充

新闻：

点选新闻标题后会调用浏览器显示新闻详细页（这里本来打算用JEditorPane实现的，实现后发现新闻网页格式变形，查询资料知道JEditorPane 存在缺陷：不支持CSS样式和JavaScript。所以改为了调用浏览器打开新闻页。）
星座：

没有找到免费的api接口，星座数据是用爬虫爬下来的，所以第一次问星座问题时出结果会有点慢。
