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:
- import java.io.BufferedReader;
- import java.io.IOException;
- import java.io.InputStreamReader;
- import java.io.OutputStreamWriter;
- import java.io.UnsupportedEncodingException;
- import java.net.MalformedURLException;
- import java.net.URL;
- import java.net.URLConnection;
- public class HttpPostTest {
- void testPost(String urlStr) {
- try {
- URL url = new URL(urlStr);
- URLConnection con = url.openConnection();
- con.setDoOutput(true);
- con.setRequestProperty("Pragma:", "no-cache");
- con.setRequestProperty("Cache-Control", "no-cache");
- con.setRequestProperty("Content-Type", "text/xml");
- OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());
- String xmlInfo = getXmlInfo();
- out.write(new String(xmlInfo));
- out.flush();
- out.close();
- BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
- String line = "";
- StringBuffer buf = new StringBuffer();
- for (line = br.readLine(); line != null; line = br.readLine()) {
- buf.append(new String(line.getBytes(),"UTF-8"));
- }
- System.out.println(buf.toString());
- } catch (MalformedURLException e) {
- e.printStackTrace();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- private String getXmlInfo() {
- // 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
- 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/">"
- + "<SOAP-ENV:Body>"
- + "<m:getItemDetailSingle xmlns:m=/"http:xxxxxxxxxxxxxxxxxx//">"
- + "<itemMo>"
- + "<category>工厂类</category>"
- + "<city>北京</city>"
- + "<flag>1</flag>"
- + "<itemId>0</itemId>"
- + "<itemIndex>1</itemIndex>"
- + "<keyword></keyword>"
- + "<mobile>2147483647</mobile>"
- + "<password>123456</password>"
- + "<userName>sohu</userName>"
- + "</itemMo>"
- + "</m:getItemDetailSingle>"
- + "</SOAP-ENV:Body>"
- + "</SOAP-ENV:Envelope>";
- return xml;
- }
- public static void main(String[] args) throws UnsupportedEncodingException {
- String url = "http://localhost:9003/dataService/services/Job";
- new HttpPostTest().testPost(url);
- }
- }
socke方式实现例子:
- import java.io.IOException;
- import java.io.InputStream;
- import java.io.InputStreamReader;
- import java.io.OutputStream;
- import java.net.Socket;
- import java.net.UnknownHostException;
- public class WebServiceClient {
- /**
- * @param args
- * @throws IOException
- * @throws UnknownHostException
- */
- public static void main(String[] args) throws UnknownHostException, IOException {
- Socket socket = new Socket("localhost",9003);
- OutputStream os = socket.getOutputStream();
- InputStream is = socket.getInputStream();
- //System.out.println(socket.isConnected());
- String httpSend = "POST /dataService/services/Job HTTP/1.1/r/n"
- + "Content-Type:text/xml/r/n"
- + "Host:localhost:9003/r/n"
- + "Content-Length:1024/r/n"
- + "/r/n"
- + "<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/">"
- + "<SOAP-ENV:Body>"
- + "<m:getItemDetailSingle xmlns:m=/"http://localhost//">"
- + "<itemMo>"
- + "<category>工厂类</category>"
- + "<city>北京</city>"
- + "<flag>1</flag>"
- + "<itemId>0</itemId>"
- + "<itemIndex>1</itemIndex>"
- + "<keyword>String</keyword>"
- + "<mobile>2147483647</mobile>"
- + "<password>123456</password>"
- + "<userName>sohu</userName>"
- + "</itemMo>"
- + "</m:getItemDetailSingle>"
- + "</SOAP-ENV:Body>"
- + "</SOAP-ENV:Envelope>";
- os.write(httpSend.getBytes());
- os.flush();
- InputStreamReader ireader = new InputStreamReader(is);
- java.io.BufferedReader breader = new java.io.BufferedReader(ireader);
- String responseLine = "";
- while((responseLine = breader.readLine()) != null)
- {
- System.out.println(new String(responseLine.getBytes(),"UTF-8"));
- }
- System.out.println("");
- }
- }
