Java调用WebService可以直接使用Apache提供的axis.jar自己编写代码，或者利用Eclipse自动生成WebServiceClient代码，利用其中的Proxy类进行调用。理论上是一样的，只不过用Eclipse自动生成代码省事些。
1、编写代码方式：
packagecom.yudun.test; importjava.rmi.RemoteException; importorg.apache.axis.client.Call; importorg.apache.axis.client.Service; importorg.apache.axis.message.PrefixedQName; importorg.apache.axis.message.SOAPHeaderElement; importcom.cezanne.golden.user.Exception; importcom.cezanne.golden.user.UserManagerServiceProxy; importjavax.xml.namespace.QName; importjava.net.MalformedURLException; importjavax.xml.rpc.ServiceException; importjavax.xml.soap.Name; importjavax.xml.soap.SOAPException; publicclasstestWebService{ publicstaticStringgetResult()throwsServiceException,MalformedURLException,RemoteException,SOAPException { //标识WebService的具体路径 Stringendpoint="WebService服务地址"; //创建Service实例 Serviceservice=newService(); //通过Service实例创建Call的实例 Callcall=(Call)service.createCall(); //将WebService的服务路径加入到call实例之中. call.setTargetEndpointAddress(newjava.net.URL(endpoint));//为Call设置服务的位置 //由于需要认证，故需要设置调用的SOAP头信息。 NameheaderName=newPrefixedQName(newQName("发布的wsdl里的targetNamespace里的url","string_itemName")); org.apache.axis.message.SOAPHeaderElementheader=newSOAPHeaderElement(headerName); header.addTextNode("blablabla"); call.addHeader(header); //SOAPHeaderElementsoapHeaderElement=newSOAPHeaderElement("发布的wsdl里的targetNamespace里的url","SoapHeader"); //soapHeaderElement.setNamespaceURI("发布的wsdl里的targetNamespace里的url"); //try //{ //soapHeaderElement.addChildElement("string_itemName").setValue("blablabla"); //} //catch(SOAPExceptione) //{ //e.printStackTrace(); //} //call.addHeader(soapHeaderElement); //调用WebService的方法 org.apache.axis.description.OperationDescoper; org.apache.axis.description.ParameterDescparam; oper=neworg.apache.axis.description.OperationDesc(); oper.setName("opName"); param=neworg.apache.axis.description.ParameterDesc(newjavax.xml.namespace.QName("","arg0"),org.apache.axis.description.ParameterDesc.IN,newjavax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema","string"),java.lang.String.class,false,false); param.setOmittable(true); oper.addParameter(param); param=neworg.apache.axis.description.ParameterDesc(newjavax.xml.namespace.QName("","arg1"),org.apache.axis.description.ParameterDesc.IN,newjavax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema","string"),java.lang.String.class,false,false); param.setOmittable(true); oper.addParameter(param); param=neworg.apache.axis.description.ParameterDesc(newjavax.xml.namespace.QName("","arg2"),org.apache.axis.description.ParameterDesc.IN,newjavax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema","string"),java.lang.String.class,false,false); param.setOmittable(true); oper.addParameter(param); oper.setReturnType(newjavax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema","string")); oper.setReturnClass(java.lang.String.class); oper.setReturnQName(newjavax.xml.namespace.QName("","return")); oper.setStyle(org.apache.axis.constants.Style.WRAPPED); oper.setUse(org.apache.axis.constants.Use.LITERAL); oper.addFault(neworg.apache.axis.description.FaultDesc( newjavax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url","Exception"), "Exception", newjavax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url","Exception"), true )); call.setOperation(oper); call.setOperationName(newjavax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url","opName")); //调用WebService,传入参数 Stringres=(String)call.invoke(newObject[]("arg0","arg1")); System.out.println("==============="); returnres; } /** *@paramargs */ publicstaticvoidmain(String[]args){ try{ System.out.println(getResult()); }catch(MalformedURLExceptione){ e.printStackTrace(); }catch(RemoteExceptione){ e.printStackTrace(); }catch(ServiceExceptione){ e.printStackTrace(); }catch(SOAPExceptione){ e.printStackTrace(); } } } |
