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。
