webservice 调用 axis，soap详解

转自： http://hardcode.iteye.com/blog/385982
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

调用java生成的webservice

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();

调用ASP.Net生成的webservice

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"
), String.
class
,

null
, sd);

smr.mapTypes(Constants.NS_URI_SOAP_ENC, new
 QName(

"http://tempuri.org/"
, 
"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,"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
;
}
