用java去访问web service 提供的电视节目预告

思路：
  1 用程序去访问 web service 服务.返回 xml文件。
  2 用dom 去解析xml
  3 用解析后的数据 生成 html文件

访问web service 的代码

public class StaticHTMLFile{
		public static boolean PrintPage(String page, String url_addr) { 
			URL url; 
			String rLine = null; 
			PrintWriter fileOut = null; 
			InputStream ins = null; 
			File file=new File(page.trim());
			
			try { 
				url = new URL(url_addr); 
				ins = url.openStream(); 
				BufferedReader bReader = new BufferedReader(new InputStreamReader(ins, 
				"utf-8"));//获取编码为utf-8的文件 
				file.createNewFile();
				FileOutputStream out = new FileOutputStream(file); 
				OutputStreamWriter writer = new OutputStreamWriter(out, "utf-8"); 
				fileOut = new PrintWriter(writer); 
				//循环取取数据,并写入目标文件中 
				while ( (rLine = bReader.readLine()) != null) { 
				String tmp_rLine = rLine; 
				int str_len = tmp_rLine.length(); 
				if (str_len > 0) { 
				fileOut.println(tmp_rLine); 
				fileOut.flush(); 
				 } 
				tmp_rLine = null; 
				} 
				url = null; 
				return true;
			} catch (IOException e) { 
				System.out.println("error: " + e.getMessage()); 
				e.printStackTrace(); 
				return false; 
			} catch (Exception es) { 
				System.out.println(es.getMessage()); 
				return false; 
			} 
			finally {//关闭资源 
				fileOut.close(); 
			try { 
				ins.close(); 
			} catch (IOException ex){ 
			//关闭输入流出错 
				ex.printStackTrace();
				} 
			}
		
		
		}

    
	
	}

把xml解析成int[]

public class DomXml2Int {

	String fileName=null;//xml的文件
	String tagName=null;//要提取的xml中标签的名字
	
	
	
	
	
	public String getFileName() {
		return fileName;
	}




	public void setFileName(String fileName) {
		this.fileName = fileName;
	}




	public String getTagName() {
		return tagName;
	}




	public void setTagName(String tagName) {
		this.tagName = tagName;
	}




	




	public List<Integer> builder() throws ParserConfigurationException, SAXException, IOException{
		
		List<Integer> ids=null;
					  ids=new ArrayList<Integer>();
		
		DocumentBuilderFactory dbf=null;
		DocumentBuilder			db=null;
		Document                d=null;
		NodeList 				nl=null;
		Node					n=null;
								dbf=DocumentBuilderFactory.newInstance();
								db=dbf.newDocumentBuilder();
								d=db.parse(fileName);
								nl=d.getElementsByTagName(tagName);
		//循环取出每个Node的值
		for(int i=0;i<nl.getLength();i++){
			n=nl.item(i);//得到每个node
			//System.out.println(n.getTextContent());
			ids.add(Integer.valueOf(n.getTextContent()));
			
		}
		
		
		
		  return ids;
	}
	
	
	
}

提取电视节目的代码

public class DomXml2String {

	/**
	 * @param args
	 * @throws ParserConfigurationException 
	 * @throws IOException 
	 * @throws SAXException 
	 */
	public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException {
		
	    System.out.println(new DomXml2String().builder("tt.xml")[0]); 
	    System.out.println(new DomXml2String().builder("tt.xml")[1]); 

	 	 

		
	}
	
	//解析xml到数组中去
	
	 public String[] builder( String xmlFilePath ) throws ParserConfigurationException, SAXException, IOException{
		 String[] tvShow= new String[2];
		 StringBuffer tvShowTempAM=new StringBuffer();
		 StringBuffer tvShowTempPM=new StringBuffer();
		 DocumentBuilderFactory dbf=null;
		   dbf=DocumentBuilderFactory.newInstance();
           DocumentBuilder db=null;
	           db=dbf.newDocumentBuilder();
           Document d=null;
                  d=db.parse(new File(xmlFilePath));
           NodeList n=null;
                    n=d.getElementsByTagName("tvProgramTable");
           Node node=null;
           //循环得到每个节点的值
           for(int i=0;i<n.getLength();i++){
        	    node=n.item(i);
        	   //System.out.println(i+node.getChildNodes().item(3).getTextContent() );
        	   if(node.getChildNodes().item(3).getTextContent().equals("AM")){
        	    	
        	    //System.out.println(i+" is am" );
        	    	tvShowTempAM.append(node.getChildNodes().item(1).getTextContent()+""+node.getChildNodes().item(5).getTextContent()+"<br>");
        	    	
        	    	
        	    }else{
        	   //	System.out.println(i+" is pm" );
        	    	
        	    	tvShowTempPM.append(node.getChildNodes().item(1).getTextContent()+""+node.getChildNodes().item(5).getTextContent()+"<br>");
        	    	
        	    }
        	   
           }
              
		 
		 tvShow[0]="AM\n"+tvShowTempAM.toString();
		 tvShow[1]="PM\n"+tvShowTempPM.toString();	
		 
		 
		 
		 return tvShow;
	 }
	

}

提取湖北省的所以电视节目

public class TVRequestWebServiceTest {

	/**
	 * @param args
	 * @throws IOException 
	 * @throws SAXException 
	 * @throws ParserConfigurationException 
	 * @throws TemplateException

	public static void main(String[] args) throws ParserConfigurationException, SAXException, IOException, TemplateException {

        List<Integer> pdIds=null;
        String[] tvShow= new String[2];

		//根据dstIds.xml得到电视台的id(int)
		DomXml2Int dxi=null;

	    String2Html s2h=null;
	    
				   
		//循环每个电视台得到每个电视的所以频道id

			StaticHTMLFile.PrintPage("E:/workspace/spring2Test/pdIds" +

	                  );
			dxi.setFileName("pdIds_"+dstIds.get(i)+".xml");
			dxi.setTagName("tvChannelID");
			pdIds=dxi.builder();//获得每个电视台的所以频道id

		                  );
			tvShow=	dx.builder("pdIds_"+dstIds.get(i)+"_"+pdIds.get(j)+".xml");

把数据转换成html的代码

public class String2Html {
	
	public static void builderHtml(String[] strS,int i,int j) throws IOException, TemplateException{
		
		//初始化freeMarker
		File file=null;
			 file=new File("E:\\workspace\\spring2Test\\htmlTest\\");
	   Configuration cf=null;
	   				cf=new Configuration();
	   				cf.setDirectoryForTemplateLoading(file);
	   	Template template=null;	
	   			 template=cf.getTemplate("tvShow.ftl");
	   	Map<String,String[]> root=null;
	   						 root=new HashMap<String,String[]>();
	   				root.put("tvShow", strS);
	   	Writer out=null;
	   		//下面的文件名: 电视台id_频道id_时间.html  
	   	out=new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File("E:/workspace/spring2Test/htmlTest/"+i+"_"+j+"_"+".html")),"utf-8"));
	   	
	   	template.process(root, out);
		
		
		
		
		
	}

}

//这里是原始的代码，需要好好整理整理。最好用soap

谢谢kimmking ，我不知道还有这样的工具

1 楼 kimmking 2009-02-21  

直接用webservice的工具来做岂不更好
