Java如何通过WSDL文件来调用这些web service

 下面我们来看Java如何通过WSDL文件来调用这些web service:

注意,以下的代码并没有经过真正的测试,只是说明这些情况,不同版本的Axis相差很大,大家最好以apache网站上的例子为准,这里仅仅用于说明其基本用法。 

1,直接AXIS调用远程的web service

我觉得这种方法比较适合那些高手,他们能直接看懂XML格式的WSDL文件,我自己是看不懂的,尤其我不是专门搞这行的,即使一段时间看懂,后来也就忘记了。直接调用模式如下:

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());

}

}

}

2,直接SOAP调用远程的webservice

这种模式我从来没有见过,也没有试过,但是网络上有人贴出来,我也转过来 

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();

}

}

}
