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?

1. package com.wxm;  
2. import javax.wsdl.*;  
3. import javax.wsdl.factory.*;  
4. import javax.wsdl.xml.*;  
5. public class ReadWsdl {  
6. public static void main(String[]args)  
7. {  
8. try{  
9. WSDLFactory factory=WSDLFactory.newInstance();  
10. WSDLReader reader=factory.newWSDLReader();  
11. reader.setFeature("javax.wsdl.verbose",true);  
12. reader.setFeature("javax.wsdl.importDocuments",true);  
13. Definition def=reader.readWSDL("http://localhost:8080/axis/services/SayHelloService?wsdl");  
14. WSDLWriter writer=factory.newWSDLWriter();  
15. writer.writeWSDL(def, System.out);  
16. }catch(WSDLException e){e.printStackTrace();}   
17. }  
18. }  

程序2：

view plaincopy to clipboardprint?

1. package com.wxm;  
2. import javax.wsdl.*;  
3. import javax.wsdl.extensions.*;  
4. import javax.wsdl.factory.*;  
5. import javax.wsdl.xml.*;  
6. import javax.xml.namespace.QName;  
7. import java.util.*;  
8. import org.w3c.dom.*;  
9. public class NavigatingWSDL {  
10. public static void main(String[]args)  
11. {  
12. try{  
13.    WSDLFactory factory=WSDLFactory.newInstance();  
14.    WSDLReader reader=factory.newWSDLReader();  
15.    reader.setFeature("javax.wsdl.verbose",true);  
16.    reader.setFeature("javax.wsdl.importDocuments",true);  
17.    Definition def=reader.readWSDL("http://localhost:8080/axis/services/SayHelloService?wsdl");  
18.          //解析服务名   
19.    System.out.println("----------");  
20.    System.out.println("nService Name:");  
21.    String tns="http://localhost:8080/axis/services/SayHelloService";  
22.         Service service =def.getService(new QName(tns,"SayHelloService"));  
23.    System.out.println(service.getQName().getLocalPart());  
24.    //解析接口方法名  
25.    System.out.println("nOperation Name:");  
26.    Port port =service.getPort("SayHelloService");  
27.    Binding binding=port.getBinding();  
28.    PortType portType=binding.getPortType();  
29.    List operations=portType.getOperations();  
30.    Iterator operIter=operations.iterator();  
31.    while(operIter.hasNext())  
32.    {  
33.     Operation operation=(Operation)operIter.next();  
34.     if(!operation.isUndefined())  
35.     {System.out.println(operation.getName()) ;}  
36.    }  
37.    //解析消息，输入输出  
38.    System.out.println("nMessages:");  
39.    Map messages=def.getMessages();  
40.    Iterator msgIter=messages.values().iterator();  
41.    while(msgIter.hasNext())  
42.    {  
43.     Message msg=(Message)msgIter.next();  
44.     if(!msg.isUndefined())  
45.     {  
46.      System.out.println(msg.getQName().getLocalPart());  
47.      Iterator partIter=msg.getParts().values().iterator();  
48.      while(partIter.hasNext())  
49.      {  
50.       Part part=(Part) partIter.next();  
51.       System.out.print("parameter name:"+part.getName()+"t");  
52.       System.out.println("parameter type:"+part.getTypeName().getLocalPart());  
53.      }  
54.     }       
55.    }  
56.    //解析服务地址  
57.    System.out.println("nService location:");  
58.    List l=port.getExtensibilityElements();  
59.    ExtensibilityElement element=(ExtensibilityElement) l.get(0);  
60.    String s=element.toString();  
61.      System.out.println(s.substring(s.indexOf("location")));  
62.      System.out.println("---------");  
63.     
64. }catch(WSDLException e){e.printStackTrace();}   
65. }  
66. }  

 可以解析出wsdl文件的服务名，操作接口名，服务地址等
