怎么写webservice( 二 )


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:package com.yudun.test;import java.rmi.RemoteException;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import org.apache.axis.message.PrefixedQName;import org.apache.axis.message.SOAPHeaderElement;import com.cezanne.golden.user.Exception;import com.cezanne.golden.user.UserManagerServiceProxy;import javax.xml.namespace.QName;import java.net.MalformedURLException;import javax.xml.rpc.ServiceException;import javax.xml.soap.Name;import javax.xml.soap.SOAPException;public class testWebService {public static String getResult() throws ServiceException, MalformedURLException, RemoteException, SOAPException { //标识Web Service的具体路径 String endpoint = "WebService服务地址"; // 创建 Service实例 Service service = new Service(); // 通过Service实例创建Call的实例 Call call = (Call) service.createCall(); //将Web Service的服务路径加入到call实例之中. call.setTargetEndpointAddress( new java.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 。
Name headerName = new PrefixedQName( new QName("发布的wsdl里的targetNamespace里的url", "string_itemName") ); org.apache.axis.message.SOAPHeaderElement header = new SOAPHeaderElement(headerName); header.addTextNode( "blablabla" ); call.addHeader(header);// SOAPHeaderElement soapHeaderElement = new SOAPHeaderElement("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 (SOAPException e) // { // e.printStackTrace(); // } // call.addHeader(soapHeaderElement); //调用Web Service的方法 org.apache.axis.description.OperationDesc oper; org.apache.axis.description.ParameterDesc param; oper = new org.apache.axis.description.OperationDesc(); oper.setName("opName"); param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg0"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName(".yudun.test;import java.rmi.RemoteException;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import org.apache.axis.message.PrefixedQName;import org.apache.axis.message.SOAPHeaderElement;import com.cezanne.golden.user.Exception;import com.cezanne.golden.user.UserManagerServiceProxy;import javax.xml.namespace.QName;import java.net.MalformedURLException;import javax.xml.rpc.ServiceException;import javax.xml.soap.Name;import javax.xml.soap.SOAPException;public class testWebService {public static String getResult() throws ServiceException, MalformedURLException, RemoteException, SOAPException { //标识Web Service的具体路径 String endpoint = "WebService服务地址"; // 创建 Service实例 Service service = new Service(); // 通过Service实例创建Call的实例 Call call = (Call) service.createCall(); //将Web Service的服务路径加入到call实例之中. call.setTargetEndpointAddress( new java.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 。
Name headerName = new PrefixedQName( new QName("发布的wsdl里的targetNamespace里的url", "string_itemName") ); org.apache.axis.message.SOAPHeaderElement header = new SOAPHeaderElement(headerName); header.addTextNode( "blablabla" ); call.addHeader(header);// SOAPHeaderElement soapHeaderElement = new SOAPHeaderElement("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 (SOAPException e) // { // e.printStackTrace(); // } // call.addHeader(soapHeaderElement); //调用Web Service的方法 org.apache.axis.description.OperationDesc oper; org.apache.axis.description.ParameterDesc param; oper = new org.apache.axis.description.OperationDesc(); oper.setName("opName"); param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg0"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, false, false); param.setOmittable(true); oper.addParameter(param); param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg1"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, false, false); param.setOmittable(true); oper.addParameter(param); param = new org.apache.axis.description.ParameterDesc(new javax.xml.namespace.QName("", "arg2"), org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, false, false); param.setOmittable(true); oper.addParameter(param); oper.setReturnType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string")); oper.setReturnClass(java.lang.String.class); oper.setReturnQName(new javax.xml.namespace.QName("", "return")); oper.setStyle(org.apache.axis.constants.Style.WRAPPED); oper.setUse(org.apache.axis.constants.Use.LITERAL); oper.addFault(new org.apache.axis.description.FaultDesc( new javax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url", "Exception"), "Exception", new javax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url", "Exception"), true )); call.setOperation( oper ); call.setOperationName(new javax.xml.namespace.QName("发布的wsdl里的targetNamespace里的url", "opName")); //调用Web Service,传入参数 String res = ( String ) call.invoke( new Object[]("arg0","arg1")); System.out.println("==============="); return res; }/** * @param args */ public static void main(String[] args) { try { System.out.println(getResult()); } catch (MalformedURLException e) { e.printStackTrace(); } catch (RemoteException e) { e.printStackTrace(); } catch (ServiceException e) { e.printStackTrace(); } catch (SOAPException e) { e.printStackTrace(); } }}2、利用Eclipse自动生成WebService client代码就容易多了:(由于还不会发图片,就用 。
