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

-->

- <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 plaincopy to clipboardprint?
  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 plaincopy to clipboardprint?
  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();}   
 }  
 }
