程序分享:从UDDI注册中心查询服务
查询服务程序的实现过程:创建Inquiry对象,并设置查询地址;声明FindBusiness对象,并设置查询服务名和相关属性;获得BusinessList对象,然后层层向下查询:BusinessList->BusinessInfo->ServiceInfo->BusinessService->BindingTemplate,最后得到AccessPoint对象,调用getText()方法,就可获得该服务的入口地。得到服务的WSDL之后,可利用WSIF调用这个服务的方法。见如下程序的方法:
public void getServicesURL(){
try{
Inquiry inq=new Inquiry();
inq.setURL("http://huijddn.com/services/uddi/inquiryapi");
FindQualifiers fqs = new FindQualifiers();
FindBusiness fb = new FindBusiness();
fb.setFindQualifiers(fqs);
fb.setName(new Name("MagazineServices"));//查找服务名MagazineServices的服务
BusinessList rBusinessList = inq.findBusiness(fb);
BusinessInfos rBusinessInfos = rBusinessList.getBusinessInfos();
Vector rBusinessInfoVector = rBusinessInfos.getBusinessInfoVector();
BusinessInfo rBusinessInfo;
for (int y =0; y < rBusinessInfoVector.size(); y++)
{
rBusinessInfo = (BusinessInfo)rBusinessInfoVector.elementAt(y);
System.out.println("*********BUSINESS INFO********");
System.out.println("Attribute BusinessKey: "+rBusinessInfo.getBusinessKey());
Name rName = rBusinessInfo.getName();
System.out.println("Name : "+rName.getValue());
Vector rDesVector = rBusinessInfo.getDescriptionVector();
Description rDes=null;
printDescriptionVector(rDesVector);
ServiceInfos rSerInfos = rBusinessInfo.getServiceInfos();
Vector rServiceInfoVector = rSerInfos.getServiceInfoVector();
ServiceInfo rServiceInfo;
for (int x =0; x<rServiceInfoVector.size();x++)
{
System.out.println("*********Service Info********");
rServiceInfo = (ServiceInfo)rServiceInfoVector.elementAt(x);
System.out.println("Service Info Name: "+rServiceInfo.getName().getValue());
System.out.println("ServiceKey : "+rServiceInfo.getServiceKey());
System.out.println("BusinessKey : "+rServiceInfo.getBusinessKey());
String magazineServer=rServiceInfo.getServiceKey();
ServiceDetail rServiceDetail = inq.getServiceDetail(gsd);
Vector rBusinessServiceVector = rServiceDetail.getBusinessServiceVector();
BusinessService rBS;
for (int a=0;a<rBusinessServiceVector.size();a++)
{
System.out.println("*****************BUSINESS SERVICE***************");
rBS = (BusinessService)rBusinessServiceVector.elementAt(a);
Vector rDesVector = rBS.getDescriptionVector();
BindingTemplates rBTs = rBS.getBindingTemplates();
if (rBTs !=null)
{
Vector rBTVector = rBTs.getBindingTemplateVector();
BindingTemplate returnBindingTemplate;
for (int i = 0; i < returnBindingTemplateVector.size(); i++)
{
System.out.println("***********BINDING TEMPLATE*************");
returnBindingTemplate =(BindingTemplate)returnBindingTemplateVector.elementAt(i);
Vector rDesVector = returnBindingTemplate.getDescriptionVector(); AccessPoint rAP = returnBindingTemplate.getAccessPoint();
java.net.URL url=new URL(rAP.getText());//找到服务的URL地址
}
}
}
}
}
}catch(Exception e){
e.printStackTrace();
}
}
