### 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 {

                        // 取得用户所选行的行数

                          // 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)：  
    ![uExKg31G5EbpVedILAr.png][]  
    新闻（显示新闻列表，点选后可进入新闻详情页）：  
    ![tcPuU6OtSRuOQEZ6fwi.png][]  
    星座（支持查今日、明日、本周、本月、今年运势）：  
    ![SM41kJD0kcFtkKxwxuN.png][]  
    成语（支持成语释义、查带某字、词的成语）：  
    ![twTmebuHGJ9pPW2PmrI.png][]  
    解梦：  
    ![7i00VNR3NMFV7ZUL1UG.png][]

### 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。
