我们知道，接口是java的一个重要概念，一切的实现都基于接口，这次，小编要为大家讲解的就是如何在java中调用webservice，下面就一下来看看。
一、AXIS远程调用web service
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";
// 直接引用远程的wsdl文件
// 以下都是套路
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(endpoint);
call.setOperationName("addUser"); // WSDL里面描述的接口名称
call.addParameter("userName"
, org.apache.axis.encoding.XMLType.XSD_DATE
, javax.xml.rpc.ParameterMode.IN); // 接口的参数
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING); // 设置返回类型
String temp = "测试人员";
String result = (String) call.invoke(new Object[]
{
temp
});
// 给方法传递参数，并且调用方法
System.out.println("result is " + result);
}
catch (Exception e)
{
System.err.println(e.toString());
}
}
}二、SOAP远程调用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();
}
}
