技术：java+Jsoup+JFrame+JTable+JTabbedPane+JScrollPane

运行环境：eclipse

概述

该程序支持功能有：笑话、新闻、星座运势、成语、解梦。其中数据来源为访问api接口和爬虫爬取（Jsoup）。

详细

### 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：
```java
            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：
```java
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) {

    				jpanel.setViewportView(areaTxt);

    				JLabel jLabel = new JLabel();
    				if (obj != null) {
    					ImageIcon image = new ImageIcon((URL) obj);
    					jLabel.setIcon(image);
    				} else {

    				}
    				jpanel.setViewportView(jLabel);
    
    			}

    			}
    			
    		}else if(retMap.containsKey("idioms")){
    		Object obj = retMap.get("idioms");

    				public void mouseReleased(MouseEvent arg0) {}});
    										
    		}
    		
    	}
    
    	}

使用Jsoup解析XML:
```java
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)：
![](/contentImages/image/20170828/uExKg31G5EbpVedILAr.png)
新闻（显示新闻列表，点选后可进入新闻详情页）：
![](/contentImages/image/20170828/tcPuU6OtSRuOQEZ6fwi.png)
星座（支持查今日、明日、本周、本月、今年运势）：
![](/contentImages/image/20170828/SM41kJD0kcFtkKxwxuN.png)
成语（支持成语释义、查带某字、词的成语）：
![](/contentImages/image/20170828/twTmebuHGJ9pPW2PmrI.png)
解梦：
![](/contentImages/image/20170828/7i00VNR3NMFV7ZUL1UG.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。
