java调用webservice服务的几种方法

java调用webservice服务的几种方法

解决方法：

webservice服务端代码参考地址：http://www.yayihouse.com/yayishuwu/chapter/1786

第一种：

URL wsUrl = new URL("http://localhost:8080/httpSMS2/ws/hi");

       HttpURLConnection conn = (HttpURLConnection) wsUrl.openConnection();

       conn.setDoInput(true);

       conn.setDoOutput(true);

       conn.setRequestMethod("POST");

       conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");

       OutputStream os = conn.getOutputStream();

       //请求体

       String soap = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:q0=\"http://test.com/\" xmlns:xsd=

\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">" +

                     "<soapenv:Body> <q0:sayHello><arg0>5555</arg0>  </q0:sayHello> </soapenv:Body> </soapenv:Envelope>";

       os.write(soap.getBytes());

       InputStream is = conn.getInputStream();

       byte[] b = new byte[1024];

       int len = 0;

       String s = "";

       while((len = is.read(b)) != -1){

           String ss = new String(b,0,len,"UTF-8");

           s += ss;

       }

       System.out.println(s);

       is.close();

       os.close();

       conn.disconnect();

第二种：

JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();

       org.apache.cxf.endpoint.Client client = dcf.createClient("http://localhost:8080/httpSMS2/ws/hi?wsdl");

     Object[] objects;

       try {

         objects = client.invoke("sayHello",new Object[]{"admin"});

         //输出调用结果

         System.out.println(objects[0].toString());

       } catch (Exception e) {

         e.printStackTrace();

       }

第三种：

JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();

       org.apache.cxf.endpoint.Client client = dcf

               .createClient("http://localhost:8080/httpSMS2/ws/hi?wsdl");

       // url为调用webService的wsdl地址

       QName name = new QName("http://test.com/", "sayHello");

       // namespace是命名空间，methodName是方法名

       String xmlStr = "aaaaaaaa";

       // paramvalue为参数值

       Object[] objects;

       try {

           objects = client.invoke(name, xmlStr);

           System.out.println(objects[0].toString());

       } catch (Exception e) {

           e.printStackTrace();

       }

第四种：

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

       factory.setServiceClass(WebServiceServerI.class);

       factory.setAddress("http://localhost:8080/httpSMS2/ws/hi?wsdl");

       WebServiceServerI client = (WebServiceServerI)factory.create();

       System.out.println(client.sayHello("2"));
