WSDL4J解析WSDL文件方法

利用wsdl4j解析WSDL文件

工具：wsdl4j1.6

解析wsdl文件是axis1.4的服务wsdl文件

wsdl文件：

<?xml version="1.0" encoding="UTF-8" ?>

- <wsdl:definitions targetNamespace="http://localhost:8080/axis/services/SayHelloService"

xmlns:apachesoap="http://xml.apache.org/xml-soap"

xmlns:impl="http://localhost:8080/axis/services/SayHelloService"

xmlns:intf="http://localhost:8080/axis/services/SayHelloService"

xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"

xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/"

xmlns:xsd="http://www.w3.org/2001/XMLSchema">

- <!--

WSDL created by Apache Axis version: 1.4

Built on Apr 22, 2006 (06:55:48 PDT)

-->

- <wsdl:message name="sayHelloResponse">

<wsdl:part name="sayHelloReturn" type="xsd:string" />

</wsdl:message>

- <wsdl:message name="sayHelloRequest">

<wsdl:part name="name" type="xsd:string" />

</wsdl:message>

- <wsdl:portType name="SayHello">

- <wsdl:operation name="sayHello" parameterOrder="name">

<wsdl:input message="impl:sayHelloRequest" name="sayHelloRequest" />

<wsdl:output message="impl:sayHelloResponse" name="sayHelloResponse" />

</wsdl:operation>

</wsdl:portType>

- <wsdl:binding name="SayHelloServiceSoapBinding" type="impl:SayHello">

<wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />

- <wsdl:operation name="sayHello">

<wsdlsoap:operation soapAction="" />

- <wsdl:input name="sayHelloRequest">

<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://hello.com" use="encoded" />

</wsdl:input>

- <wsdl:output name="sayHelloResponse">

<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:8080/axis/services/SayHelloService" use="encoded" />

</wsdl:output>

</wsdl:operation>

</wsdl:binding>

- <wsdl:service name="SayHelloService">

- <wsdl:port binding="impl:SayHelloServiceSoapBinding" name="SayHelloService">

<wsdlsoap:address location="http://localhost:8080/axis/services/SayHelloService" />

</wsdl:port>

</wsdl:service>

</wsdl:definitions>

下面是两个程序wsdl4j编写：

程序1：

view plain copy to clipboard print ?

package com.wxm;
import javax.wsdl.*;
import javax.wsdl.factory.*;
import javax.wsdl.xml.*;
public class ReadWsdl {
public static void main(String[]args)
{
try{
WSDLFactory factory=WSDLFactory.newInstance();
WSDLReader reader=factory.newWSDLReader();
reader.setFeature("javax.wsdl.verbose",true);
reader.setFeature("javax.wsdl.importDocuments",true);
Definition def=reader.readWSDL("http://localhost:8080/axis/services/SayHelloService?wsdl");
WSDLWriter writer=factory.newWSDLWriter();
writer.writeWSDL(def, System.out);
}catch(WSDLException e){e.printStackTrace();}
}
}

程序2：

view plain copy to clipboard print ?

package com.wxm;
import javax.wsdl.*;
import javax.wsdl.extensions.*;
import javax.wsdl.factory.*;
import javax.wsdl.xml.*;
import javax.xml.namespace.QName;
import java.util.*;
import org.w3c.dom.*;
public class NavigatingWSDL {
public static void main(String[]args)
{
try{
WSDLFactory factory=WSDLFactory.newInstance();
WSDLReader reader=factory.newWSDLReader();
reader.setFeature("javax.wsdl.verbose",true);
reader.setFeature("javax.wsdl.importDocuments",true);
Definition def=reader.readWSDL("http://localhost:8080/axis/services/SayHelloService?wsdl");
//解析服务名
System.out.println("----------");
System.out.println("nService Name:");
String tns="http://localhost:8080/axis/services/SayHelloService";
Service service =def.getService(new QName(tns,"SayHelloService"));
System.out.println(service.getQName().getLocalPart());
//解析接口方法名
System.out.println("nOperation Name:");
Port port =service.getPort("SayHelloService");
Binding binding=port.getBinding();
PortType portType=binding.getPortType();
List operations=portType.getOperations();
Iterator operIter=operations.iterator();
while(operIter.hasNext())
{
Operation operation=(Operation)operIter.next();
if(!operation.isUndefined())
{System.out.println(operation.getName()) ;}
}
//解析消息，输入输出
System.out.println("nMessages:");
Map messages=def.getMessages();
Iterator msgIter=messages.values().iterator();
while(msgIter.hasNext())
{
Message msg=(Message)msgIter.next();
if(!msg.isUndefined())
{
System.out.println(msg.getQName().getLocalPart());
Iterator partIter=msg.getParts().values().iterator();
while(partIter.hasNext())
{
Part part=(Part) partIter.next();
System.out.print("parameter name:"+part.getName()+"t");
System.out.println("parameter type:"+part.getTypeName().getLocalPart());
}
}
}
//解析服务地址
System.out.println("nService location:");
List l=port.getExtensibilityElements();
ExtensibilityElement element=(ExtensibilityElement) l.get(0);
String s=element.toString();
System.out.println(s.substring(s.indexOf("location")));
System.out.println("---------");
}catch(WSDLException e){e.printStackTrace();}
}
}

可以解析出wsdl文件的服务名，操作接口名，服务地址等
