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。
