java简单实现webservice接口

 

webservice实现有多种方式

比如最常用的有axis框架,xfire框架,通过该框架可以发布wsdl接口,也可以实现webservice客户端,目前eclipse都有集 成的插件,可以根据wsdl文件生成webservice客户端调用接口,但是这样部署的时候必须依赖框架的jar包,有时候可能因为环境等等原因,我们 仅仅需要wsdl中的某一个接口,这时候可以通过http接口或socket接口直接发生xml数据,来调用服务端webservice服务,其实 webservice底层还是发送xml数据,只是框架封装了对xml数据进行序列化与反序列化操作,下面以两个简单的例子说明http方式和 socket方式。

 

 

http实现webservice接口调用例子:

[c-sharp] view plain copy
  1. import java.io.BufferedReader;  
  2. import java.io.IOException;  
  3. import java.io.InputStreamReader;  
  4. import java.io.OutputStreamWriter;  
  5. import java.io.UnsupportedEncodingException;  
  6. import java.net.MalformedURLException;  
  7. import java.net.URL;  
  8. import java.net.URLConnection;  
  9.   
  10. public class HttpPostTest {  
  11.     void testPost(String urlStr) {  
  12.         try {  
  13.             URL url = new URL(urlStr);  
  14.             URLConnection con = url.openConnection();  
  15.             con.setDoOutput(true);  
  16.             con.setRequestProperty("Pragma:", "no-cache");  
  17.             con.setRequestProperty("Cache-Control", "no-cache");  
  18.             con.setRequestProperty("Content-Type", "text/xml");  
  19.               
  20.             OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());      
  21.             String xmlInfo = getXmlInfo();  
  22.             out.write(new String(xmlInfo));  
  23.             out.flush();  
  24.             out.close();  
  25.             BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));  
  26.             String line = "";  
  27.             StringBuffer buf = new StringBuffer();  
  28.             for (line = br.readLine(); line != null; line = br.readLine()) {  
  29.                 buf.append(new String(line.getBytes(),"UTF-8"));  
  30.             }  
  31.             System.out.println(buf.toString());  
  32.         } catch (MalformedURLException e) {  
  33.             e.printStackTrace();  
  34.         } catch (IOException e) {  
  35.             e.printStackTrace();  
  36.         }  
  37.     }  
  38.   
  39.     private String getXmlInfo() {  
  40.         // 通过wsdl文件可以查看接口xml格式数据,构造调用接口xml数据  
  41.         String xml = "<SOAP-ENV:Envelope xmlns:SOAP-ENV=/"http://schemas.xmlsoap.org/soap/envelope//" xmlns:SOAP-ENC=/"http://schemas.xmlsoap.org/soap/encoding//" xmlns:xsi=/"http://www.w3.org/2001/XMLSchema-instance/" xmlns:xsd=/"http://www.w3.org/2001/XMLSchema/">"  
  42.                     + "<SOAP-ENV:Body>"  
  43.                     +    "<m:getItemDetailSingle xmlns:m=/"http:xxxxxxxxxxxxxxxxxx//">"  
  44.                     +        "<itemMo>"  
  45.                     +            "<category>工厂类</category>"  
  46.                     +            "<city>北京</city>"  
  47.                     +            "<flag>1</flag>"  
  48.                     +            "<itemId>0</itemId>"  
  49.                     +            "<itemIndex>1</itemIndex>"  
  50.                     +            "<keyword></keyword>"  
  51.                     +            "<mobile>2147483647</mobile>"  
  52.                     +            "<password>123456</password>"  
  53.                     +            "<userName>sohu</userName>"  
  54.                     +        "</itemMo>"  
  55.                     +    "</m:getItemDetailSingle>"  
  56.                     + "</SOAP-ENV:Body>"  
  57.                     + "</SOAP-ENV:Envelope>";  
  58.         return xml;  
  59.     }  
  60.   
  61.     public static void main(String[] args) throws UnsupportedEncodingException {  
  62.         String url = "http://localhost:9003/dataService/services/Job";  
  63.         new HttpPostTest().testPost(url);  
  64.     }  
  65. }
