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(){  @Overridepublic void stateChanged(ChangeEvent arg0) {// TODO Auto-generated method stubint 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(){@Overridepublic 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();}}                       }@Overridepublic void mouseEntered(MouseEvent arg0) {}@Overridepublic void mouseExited(MouseEvent arg0) {}@Overridepublic void mousePressed(MouseEvent arg0) {}@Overridepublic 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(){@Overridepublic 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);}                       }@Overridepublic void mouseEntered(MouseEvent arg0) {}@Overridepublic void mouseExited(MouseEvent arg0) {}@Overridepublic void mousePressed(MouseEvent arg0) {}@Overridepublic 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(){@Overridepublic 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);}                       }@Overridepublic void mouseEntered(MouseEvent arg0) {}@Overridepublic void mouseExited(MouseEvent arg0) {}@Overridepublic void mousePressed(MouseEvent arg0) {}@Overridepublic 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()));//itemElements 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。
