java调用webservice .
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
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;
}
