我使用了code first方式来开发，但是在导出的时候出了问题：重载的方法不能正确解析，貌似没有使用wrapped方式来进行soap的绑定。
用cxf自带的spring_http的例子改了一下，发先不能通过： HelloWorld.java package demo.spring;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
@WebService
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public interface HelloWorld {
String sayHi(String text);
String sayHi();
}
HelloWorldImpl.java package demo.spring;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
@WebService(endpointInterface = "demo.spring.HelloWorld")
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public class HelloWorldImpl implements HelloWorld {
private String who = "nobody";
public void setWho(String who) {
this.who = who;
}
public String sayHi(String text) {
return who + " KISS " + text;
}
public String sayHi(){
return sayHi("nobody");
}
}
这样，在启动tomcat的时候就会报错： 引用 2007/09/21 9:07:21 org.springframework.web.context.ContextLoader initWebApplicationContext

#先前搞错了。
按照wiki上的方法试了一下，也不行。 把配置文件里的 <jaxws:endpoint id="helloWorld" implementor="#helloWorldImpl" address="/HelloWorld"/> 改成 <jaxws:endpoint id="helloWorld" implementor="#helloWorldImpl" address="/HelloWorld"> <jaxws:serviceFactory> <bean class="org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean"> <property name="wrapped" value="true" /> </bean> </jaxws:serviceFactory> </jaxws:endpoint> 状况依旧。 莫非这是CXF的bug？ |

好像真是CXF的bug。
看看这一段： protected OperationInfo createOperation(ServiceInfo serviceInfo, InterfaceInfo intf, Method m) {
OperationInfo op = intf.addOperation(getOperationName(intf, m));
然而ReflectionServiceFactoryBean在getOperationName的时候，并没有考虑重载时wrapped，所以对重载方法会返回相同的QName。 而InterfaceInfo的addOperation方法 public OperationInfo addOperation(QName oname) {
if (oname == null) {
throw new NullPointerException(
new Message("OPERATION.NAME.NOT.NULL", LOG).toString());
}
if (operations.containsKey(oname)) {
throw new IllegalArgumentException(
new Message("DUPLICATED.OPERATION.NAME", LOG, new Object[]{oname}).toString());
}
OperationInfo operation = new OperationInfo(this, oname);
addOperation(operation);
return operation;
}
对于相同的QName会马上抛出异常。 貌似唯一的方法就是使用@WebMethod来重命名方法了。 :( |

搞定！
@WebMethod(operationName="xxxxx")确实能起作用。 但是比xfire的自动wrapped麻烦了些。 怀念xfire…… |

这个其实是因为WSDL里面的document/literal wrapped 规定的.
你加了@WebMethod(OperationName=...)实际上对于wsdl来说,你就是修改了他的WebMethod名字,所以就可以了. Xfire以前可以,应该是因为他自动给你改个名字,唯一不同的是,你现在需要显示的用annotation来改.以前是自动改. 关于wsdl的几种style, 请参考: http://www.ibm.com/developerworks/webservices/library/ws-whichwsdl/ |
