CXF实践中异常总结【记录收藏篇】

CXF发布WebService以及调用WebService，网上有很多实践的demo。但是根据网上的 demo不断实践，熟练掌握CXF的使用，以及总结开发CXF的异常。

CXF发布服务，有三种形式：根据main方法发布【Java Project项目】；不基于Spring方式发布到Web容器中，比如Tomcat容器【web项目】；基于Spring方式发布到Web容器中。【web项目】

因为CXF的特性之一，与Spring框架很好的集成。但是若是项目中不要求用Spring框架，但是又必须要求使用CXF框架呢？嘻嘻，所以，每个方式都需要掌握。

但是，既然每个框架都有自己的特性，所以应该扬长避短。

那我们总结一下，开发过程中，遇到的问题：

第一：若出现以下问题：

**\[html\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  Exception in thread "main" java.lang.NoSuchMethodError: javax.wsdl.xml.WSDLReader.readWSDL(Ljavax/wsdl/xml/WSDLLocator;Lorg/w3c/dom/Element;)Ljavax/wsdl/Definition;
2.  at org.apache.cxf.wsdl11.WSDLManagerImpl.loadDefinition(WSDLManagerImpl.java:247)
3.  at org.apache.cxf.wsdl11.WSDLManagerImpl.getDefinition(WSDLManagerImpl.java:192)

5.  at org.apache.cxf.endpoint.dynamic.DynamicClientFactory.createClient(DynamicClientFactory.java:292)
6.  at org.apache.cxf.endpoint.dynamic.DynamicClientFactory.createClient(DynamicClientFactory.java:235)

8.  at org.apache.cxf.endpoint.dynamic.DynamicClientFactory.createClient(DynamicClientFactory.java:183)
9.  at com.client.JaxWsDynamicClient.main(JaxWsDynamicClient.java:10 )

Exception in thread "main" java.lang.NoSuchMethodError: javax.wsdl.xml.WSDLReader.readWSDL(Ljavax/wsdl/xml/WSDLLocator;Lorg/w3c/dom/Element;)Ljavax/wsdl/Definition;

         at com.client.JaxWsDynamicClient.main(JaxWsDynamicClient.java:10 )

异常分析原因：

jar包冲突问题； 在tomcat下lib下有个wsdl-1.5.jar,而在cxf中则要使用的wsdl-1.6.jar。

解决方案：

把tomcat下的wsdl-1.5.jar去掉。【暂时为了此项目去掉】

第二：若使用动态调用wsdl方式调用服务端时，出现以下异常：

**\[html\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

异常分析原因：

wsdl的问题。

解决方案：注意wsdl后面必须添加上"?wsdl"
