org.apache.cxf.common.i18n.UncheckedException: No operation was found with the name

前言：

      在一个JavaWeb项目中，要接入WebService时，使用CXF。启动已经成功，接口也已经成功发布，但是在调用的时候报出如下异常：

org.apache.cxf.common.i18n.UncheckedException: No operation was found with the name {http://impl.webservice.barcode.*****.com/}TestService.at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:332)at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:326)at com.yealink.barcode.junit.WebServiceTest.testwebclient(WebServiceTest.java:52)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44)at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15)at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41)at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20)at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:74)at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:82)at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:72)at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:240)at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50)at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193)at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52)at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191)at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42)at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184)at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61)at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70)at org.junit.runners.ParentRunner.run(ParentRunner.java:236)at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:180)at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50)at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390)at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

解决过程：

      看报错情况，好像是项目没有查找到TestService这个方法，但是从wsdl中，可以看到，有存在这个方法。

      Attach cxf2.6.0的源码进行跟踪，后来发现，cxf会在其内部用一个map来保存QName,而这个map里，有validCodeReq，但是前半部分不对，不是 {http://impl.webservice.barcode.*****.com/}，而是{http://webservice.barcode.*****.com/}。原来是命名空间的问题！返回服务端代码，在服务实现类的注解

@WebService(targetNamespace = "http://webservice.barcode.*****.com/",endpointInterface = "com.*****.barcode.webservice.WebServices") 

     这下，问题解决。

PS：从这个错误中可以看出，如若我们的webservice接口和实现类Impl放置在同一个包下，而不分包，就不会有这个错误。
