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：

import java.io.BufferedReader;<br /> import java.io.IOException;<br /> import java.io.InputStreamReader;<br /> import java.io.OutputStreamWriter;<br /> import java.io.UnsupportedEncodingException;<br /> import java.net.MalformedURLException;<br /> import java.net.URL;<br /> import java.net.URLConnection;</p> <p>public class HttpPostTest {<br /> void testPost(String urlStr) {<br /> try {<br /> URL url = new URL(urlStr);<br /> URLConnection con = url.openConnection();<br /> con.setDoOutput(true);<br /> con.setRequestProperty("Pragma:", "no-cache");<br /> con.setRequestProperty("Cache-Control", "no-cache");<br /> con.setRequestProperty("Content-Type", "text/xml");</p> <p> OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());<br /> String xmlInfo = getXmlInfo();<br /> out.write(new String(xmlInfo));<br /> out.flush();<br /> out.close();<br /> BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));<br /> String line = "";<br /> StringBuffer buf = new StringBuffer();<br /> for (line = br.readLine(); line != null; line = br.readLine()) {<br /> buf.append(new String(line.getBytes(),"UTF-8"));<br /> }<br /> System.out.println(buf.toString());<br /> } catch (MalformedURLException e) {<br /> e.printStackTrace();<br /> } catch (IOException e) {<br /> e.printStackTrace();<br /> }<br /> }</p> <p> private String getXmlInfo() {<br /> // 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<br /> 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/">"<br /> + "<SOAP-ENV:Body>"<br /> + "<m:getItemDetailSingle xmlns:m=/"http:xxxxxxxxxxxxxxxxxx//">"<br /> + "<itemMo>"<br /> + "<category>工厂类</category>"<br /> + "<city>北京</city>"<br /> + "<flag>1</flag>"<br /> + "<itemId>0</itemId>"<br /> + "<itemIndex>1</itemIndex>"<br /> + "<keyword></keyword>"<br /> + "<mobile>2147483647</mobile>"<br /> + "<password>123456</password>"<br /> + "<userName>sohu</userName>"<br /> + "</itemMo>"<br /> + "</m:getItemDetailSingle>"<br /> + "</SOAP-ENV:Body>"<br /> + "</SOAP-ENV:Envelope>";<br /> return xml;<br /> }</p> <p> public static void main(String[] args) throws UnsupportedEncodingException {<br /> String url = "http://localhost:9003/dataService/services/Job";<br /> new HttpPostTest().testPost(url);<br /> }<br /> }<br />

socke方式实现例子：

import java.io.IOException;<br /> import java.io.InputStream;<br /> import java.io.InputStreamReader;<br /> import java.io.OutputStream;<br /> import java.net.Socket;<br /> import java.net.UnknownHostException;</p> <p>public class WebServiceClient {</p> <p> /**<br /> * @param args<br /> * @throws IOException<br /> * @throws UnknownHostException<br /> */<br /> public static void main(String[] args) throws UnknownHostException, IOException {<br /> Socket socket = new Socket("localhost",9003);<br /> OutputStream os = socket.getOutputStream();<br /> InputStream is = socket.getInputStream();<br /> //System.out.println(socket.isConnected());<br /> String httpSend = "POST /dataService/services/Job HTTP/1.1/r/n"<br /> + "Content-Type:text/xml/r/n"<br /> + "Host:localhost:9003/r/n"<br /> + "Content-Length:1024/r/n"<br /> + "/r/n"<br /> + "<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/">"<br /> + "<SOAP-ENV:Body>"<br /> + "<m:getItemDetailSingle xmlns:m=/"http://localhost//">"<br /> + "<itemMo>"<br /> + "<category>工厂类</category>"<br /> + "<city>北京</city>"<br /> + "<flag>1</flag>"<br /> + "<itemId>0</itemId>"<br /> + "<itemIndex>1</itemIndex>"<br /> + "<keyword>String</keyword>"<br /> + "<mobile>2147483647</mobile>"<br /> + "<password>123456</password>"<br /> + "<userName>sohu</userName>"<br /> + "</itemMo>"<br /> + "</m:getItemDetailSingle>"<br /> + "</SOAP-ENV:Body>"<br /> + "</SOAP-ENV:Envelope>";<br /> os.write(httpSend.getBytes());<br /> os.flush(); </p> <p> InputStreamReader ireader = new InputStreamReader(is);<br /> java.io.BufferedReader breader = new java.io.BufferedReader(ireader); </p> <p> String responseLine = ""; </p> <p> while((responseLine = breader.readLine()) != null)<br /> {<br /> System.out.println(new String(responseLine.getBytes(),"UTF-8"));<br /> } </p> <p> System.out.println(""); </p> <p> }</p> <p>}<br />
