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 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. }catch(WSDLException e){e.printStackTrace();}
64. }
65. }

可以解析出wsdl文件的服务名，操作接口名，服务地址等
