育才学习网1.webservice接口怎么写
以java为例：ava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WebService Client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：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("mons-discovery-0.2.jar
commons-logging-1.0.4.jar
jaxrpc.jar
log4j-1.2.8.jar
mailapi.jar
saaj.jar
wsdl4j-1.5.1.jar
xmlsec-1.3.0.jar
5、测试发布的WEB应用
启动Tomcat服务，打开IE浏览器，访问mons-discovery-0.2.jar
commons-logging-1.0.4.jar
jaxrpc.jar
log4j-1.2.8.jar
mailapi.jar
saaj.jar
wsdl4j-1.5.1.jar
xmlsec-1.3.0.jar
5、测试发布的WEB应用
启动Tomcat服务，打开IE浏览器，访问.*;import java.util.vector; public class caservice{ public static string getservice(string user) { url url = null; try { url=new url("http://192.168.0.100:8080/ca3/services/casynrochnized"); } catch (malformedurlexception mue) { return mue.getmessage(); } // this is the main soap object call soapcall = new call(); // use soap encoding soapcall.setencodingstyleuri(constants.ns_uri_soap_enc); // this is the remote object we're asking for the price soapcall.settargetobjecturi("urn:xmethods-casynrochnized"); // this is the name of the method on the above object soapcall.setmethodname("getuser"); // we need to send the isbn number as an input parameter to the method vector soapparams = new vector(); // name, type, value, encoding style parameter isbnparam = new parameter("username", string.class, user, null); soapparams.addelement(isbnparam); soapcall.setparams(soapparams); try { // invoke the remote method on the object response soapresponse = soapcall.invoke(url,""); // check to see if there is an error, return "n/a" if (soapresponse.generatedfault()) { fault fault = soapresponse.getfault(); string f = fault.getfaultstring(); return f; } else { // read result parameter soapresult = soapresponse.getreturnvalue (); // get a string from the result return soapresult.getvalue().tostring(); } } catch (soapexception se) { return se.getmessage(); } }}3，使用wsdl2java把wsdl文件转成本地类，然后像本地类一样使用，即可。
