Java - Webservice调用方式详解调用webservice，可以首先根据wsdl文件生成客户端，或者直接根据地址调用，下面讨论直接调用地址的两种不同方式：axis和Soap，soap方式主要是用在websphere下axis方式调用：import java.util.Date;import java.text.DateFormat;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import space.QName;import java.lang.Integer;import javax.xml.rpc.ParameterMode;public class caClient public static void main(String args) try String endpoint = http:/localhost:8080/ca3/services/caSynrochnized?wsdl;Service service = new Service();Call call = (Call) service.createCall();call.setTargetEndpointAddress(endpoint);call.setOperationName(addUser);call.addParameter(userName, org.apache.axis.encoding.XMLType.XSD_DATE,javax.xml.rpc.ParameterMode.IN);call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);call.setUseSOAPAction(true);call.setSOAPActionURI(/Rpc);/Integer k = (Integer) call.invoke(new Object i, j );/System.out.println(result is + k.toString() + .);String temp = 测试人员;String result = (String)call.invoke(new Objecttemp);System.out.println(result is +result);catch (Exception e) System.err.println(e.toString();soap方式调用import org.apache.soap.util.xml.*;import org.apache.soap.*;import org.apache.soap.rpc.*;import java.io.*;import .*;import java.util.Vector;public class caServicepublic static String getService(String user) URL url = null;try url=new URL(00:8080/ca3/services/caSynrochnized); catch (MalformedURLException mue) return mue.getMessage();/ This is the main SOAP objectCall soapCall = new Call();/ Use SOAP encodingsoapCall.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);/ This is the remote object were asking for the pricesoapCall.setTargetObjectURI(urn:xmethods-caSynrochnized);/ This is the name of the method on the above objectsoapCall.setMethodName(getUser);/ We need to send the ISBN number as an input parameter to the methodVector soapParams = new Vector();/ name, type, value, encoding styleParameter isbnParam = new Parameter(userName, String.class, user, null);soapParams.addElement(isbnParam);soapCall.setParams(soapParams);try / Invoke the remote method on the objectResponse soapResponse = soapCall.invoke(url,);/ Check to see if there is an error, return N/Aif (soapResponse.generatedFault() Fault fault = soapResponse.getFault();String f = fault.getFaultString();return f; else / read resultParameter soapResult = soapResponse.getReturnValue ();/ get a string from the resultreturn soapResult.getValue().toString(); catch (SOAPException se) return se.getMessage();返回一维数组时Parameter soapResult = soapResponse.getReturnValue();String temp = (String)soapResult.getValue();调用ASP.Net生成的webserviceprivate String HelloWorld(String uri, String u) try SOAPMappingRegistry smr = new SOAPMappingRegistry();StringDeserializer sd = new StringDeserializer();ArraySerializer arraySer = new ArraySerializer();BeanSerializer beanSer = new BeanSerializer();smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(/, HelloWorldResult), String.class,null, sd);smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName(/, temp), String.class,beanSer, beanSer);URL url = new URL(uri);Call call = new Call();call.setSOAPMappingRegistry(smr);call.setTargetObjectURI(urn:xmethods-Service1);call.setMethodName(HelloWorld);call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);Vector soapParams = new Vector();soapParams.addElement(new Parameter(temp, String.class, u, null);call.setParams(soapParams);Response soapResponse = call.invoke(url,/HelloWorld);if (soapResponse.generatedFault() Fault fault = soapResponse.getFault();System.out.p
