Webservice调用方式：axis，soap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 javax.xml.namespace.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("http://www.my.com/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 Object[]{temp});

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 java.net.*;

import java.util.Vector;


public class caService{

public static String getService(String user) {

URL url = null;

try {

url=new URL("http://192.168.0.100:8080/ca3/services/caSynrochnized");

} catch (MalformedURLException mue) {

return mue.getMessage();

}

// This is the main SOAP object

Call soapCall = new Call();

// Use SOAP encoding

soapCall.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);

// This is the remote object we're asking for the price

soapCall.setTargetObjectURI("urn:xmethods-caSynrochnized");

// This is the name of the method on the above object

soapCall.setMethodName("getUser");

// We need to send the ISBN number as an input parameter to the method

Vector soapParams = new Vector();


// name,type,value,encoding style

Parameter isbnParam = new Parameter("userName",String.class,user,null);

soapParams.addElement(isbnParam);

soapCall.setParams(soapParams);

try {

// Invoke the remote method on the object

Response soapResponse = soapCall.invoke(url,"");

// Check to see if there is an error,return "N/A"

if (soapResponse.generatedFault()) {

Fault fault = soapResponse.getFault();

String f = fault.getFaultString();

return f;

} else {

// read result

Parameter soapResult = soapResponse.getReturnValue ();

// get a string from the result

return 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();

private 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("http://tempuri.org/","HelloWorldResult"),null,sd);smr.mapTypes(Constants.NS_URI_SOAP_ENC,"temp"),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",u,null));call.setParams(soapParams);Response soapResponse = call.invoke(url,"http://tempuri.org/HelloWorld");if (soapResponse.generatedFault()) {Fault fault = soapResponse.getFault();System.out.println(fault);} else {Parameter soapResult = soapResponse.getReturnValue();Object obj = soapResult.getValue();System.out.println("===" + obj);}} catch (Exception e) {e.printStackTrace();}return null;}?
