生活中我們會遇到許許多多的奇葩問題，而這些問題又是我們不得不解決的。

　　我先用一段代碼來引出我想要說的內容：

import javax.jws.WebMethod; import javax.jws.WebService;/*** Created by 30721 on 2018/9/28.*/ @WebService public interface WstwoInter {@WebMethodString getInfo(String xml); } import cn.cy.webservice.inter.WstwoInter; import org.springframework.stereotype.Component;/*** Created by 30721 on 2018/9/28.*/ @Component public class WstwoImpl implements WstwoInter {@Overridepublic String getInfo(String xml) {System.out.println(xml);return xml;} }

而如果用org.apache.axis.client.Call類來調用就要這樣寫：

public static void main(String[] args) {try {String url = "http://127.0.0.1:8002/cxf/service/webtwo?wsdl";Service service = new Service();Call call = (Call) service.createCall();call.setTargetEndpointAddress(url);QName qName = new QName("http://inter.webservice.cy.cn/", "getInfo");call.setOperationName(qName);// WSDL里面描述的接口名稱QName qname = new QName("arg0");call.addParameter(qname, XMLType.XSD_STRING, ParameterMode.IN);// 接口的參數call.setReturnType(XMLType.XSD_STRING);// 設置返回類型String temp = "測試人員";String result = (String) call.invoke(new Object[] { temp }); // 給方法傳遞參數，并且調用方法System.out.println("result is " + result);} catch (Exception e) {e.printStackTrace();}} 描述wsdl中的方法需要帶上命名空間（我這邊的webservice的命名空間為：http://inter.webservice.cy.cn/）

如果使用則會報如下的錯誤：

Expected {http://inter.webservice.cy.cn/}getInfo.at org.apache.axis.message.SOAPFaultBuilder.createFault(SOAPFaultBuilder.java:222)at org.apache.axis.message.SOAPFaultBuilder.endElement(SOAPFaultBuilder.java:129)at org.apache.axis.encoding.DeserializationContext.endElement(DeserializationContext.java:1087)at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(AbstractSAXParser.java:609)at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEndElement(XMLDocumentFragmentScannerImpl.java:1776)at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2964)at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:606)at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:118)at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:504)at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:848)at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:777)at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:141)at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1213)at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:643)at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl.parse(SAXParserImpl.java:327)at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227)at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696)at org.apache.axis.Message.getSOAPEnvelope(Message.java:435)at org.apache.axis.transport.http.HTTPSender.readFromSocket(HTTPSender.java:796)at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:144)at org.apache.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java:32)at org.apache.axis.SimpleChain.doVisiting(SimpleChain.java:118)at org.apache.axis.SimpleChain.invoke(SimpleChain.java:83)at org.apache.axis.client.AxisClient.invoke(AxisClient.java:165)at org.apache.axis.client.Call.invokeEngine(Call.java:2784)at org.apache.axis.client.Call.invoke(Call.java:2767)at org.apache.axis.client.Call.invoke(Call.java:2443)at org.apache.axis.client.Call.invoke(Call.java:2366)at org.apache.axis.client.Call.invoke(Call.java:1812)at cn.cy.core.Main.main(Main.java:31) AxisFaultfaultCode: {http://schemas.xmlsoap.org/soap/envelope/}Client faultSubcode: faultString: Unexpected wrapper element getInfo found.

?正常情況下接口交接都是服務端的服務寫好了，然后客戶端是直接根據寫好的服務進行調用測試，然而我并非這樣子的，與我交接的公司的接口平臺是現成的，而且是老系統沒有源碼無法做修改。

?這就很尷尬了，沒辦法只能服務端代碼改了，不過工作量不大還好，他們發編譯老系統的代碼后給我發了一段這樣的客戶端代碼：

String url = "http://127.0.0.1:8002/cxf/service/webtwo?wsdl";Service service = new Service();Call call = (Call) service.createCall();call.setTargetEndpointAddress(url);QName qName = new QName("http://inter.webservice.cy.cn/", "getInfo");call.setOperationName(qName);// WSDL里面描述的接口名稱QName qname = new QName("http://inter.webservice.cy.cn/", "arg0");call.addParameter(qname, XMLType.XSD_STRING, ParameterMode.IN);// 接口的參數call.setReturnType(XMLType.XSD_STRING);// 設置返回類型String temp = "測試人員";String result = (String) call.invoke(new Object[] { temp }); // 給方法傳遞參數，并且調用方法System.out.println("result is " + result); View Code

?

我看了一下代碼發現與上面代碼的區別就是參數那邊也要帶上命名空間地址。那么服務端的接口就需要這樣改： @WebService(targetNamespace="http://inter.webservice.cy.cn/") public interface WstwoInter {@WebMethodString getInfo(@WebParam(targetNamespace="http://inter.webservice.cy.cn/") String xml); } View Code

?

這都是小問題，但是大問題出現了，服務發上去他們還是調用不到，發現還少了一個參數call.setUseSOAPAction(true);call.setSOAPActionURI(actionURI);這個參數者對應著@WebMethod(action=actionURI) 這個注釋。代碼： @WebService(targetNamespace="http://inter.webservice.cy.cn/") public interface WstwoInter {@WebMethod(action="getInfo")String getInfo(@WebParam(targetNamespace="http://inter.webservice.cy.cn/") String xml); } View Code

?

但是問題并非出在這個注釋，而是出在老系統調用這個actionURI的時候竟然是帶IP的，這樣就讓服務端的代碼移植性變的非常差。測試環境和生產環境必然是兩個不同的服務器不同的IP，不可能每次都修改代碼上的注解

@WebMethod(action="http://ip/xxx")ip，不現實。這時他們又說了接口平臺的另一個調用方式。不使用命名空間。代碼如下： public static void main(String[] args) {try {String url = "http://127.0.0.1:8002/cxf/service/webtwo?wsdl";Service service = new Service();Call call = (Call) service.createCall();call.setUseSOAPAction(true);call.setTargetEndpointAddress(url);QName qName = new QName("getInfo");call.setOperationName(qName);// WSDL里面描述的接口名稱QName qname = new QName("arg0");call.addParameter(qname, XMLType.XSD_STRING, ParameterMode.IN);// 接口的參數call.setSOAPActionURI("getInfo");call.setReturnType(XMLType.XSD_STRING);// 設置返回類型String temp = "測試人員";String result = (String) call.invoke(new Object[] { temp }); // 給方法傳遞參數，并且調用方法System.out.println("result is " + result);} catch (Exception e) {e.printStackTrace();}} View Code

?

這段代碼少了命名空間，多了一個actionURI，但是這個URI跟上面的不同，這個URI帶的是方法名，沒辦法，他們改不了，只能我們服務端來改了。我這樣子改： @WebService @SOAPBinding(style = SOAPBinding.Style.RPC, use = SOAPBinding.Use.ENCODED) public interface WstwoInter {@WebMethod(action="getInfo")String getInfo(String xml); }

?

終于接口跟他們調通了。

如果想深入理解@SOAPBinding這個注解，可參考https://blog.csdn.net/comman1999/article/details/1967907。
