Question

我使用grails cxf-Plugin并且它在本地工作正常，但是当我在tomcat服务器上部署它时我得到了一个Erro：

ERROR context.GrailsContextLoaderListener  - Error initializing the application: Error creating bean with name 'cxf':

这是我的BuildConfig的片段：

    compile ":ws-client:1.0"
    compile ":cxf-client:2.1.1"
    compile ":cxf:2.1.1"

我使用grails war构建war文件并将其部署在Tomcat服务器上我已经检查了Tomcat服务器上项目的WEB-INF/lib文件夹，并且有jar：

cxf-bundle-2.2.4.jar
cxf-core-3.0.4.jar
cxf-rt-bindings-soap-3.0.4.jar
cxf-rt-bindings-xml-3.0.4.jar 
cxf-rt-databinding-jaxb-3.0.4.jar
cxf-rt-frontend-jaxrs-3.0.4.jar
cxf-rt-frontend-jaxws-3.0.4.jar
cxf-rt-frontend-simple-3.0.4.jar
cxf-rt-security-3.0.4.jar
cxf-rt-transports-http-3.0.4.jar
cxf-rt-ws-addr-3.0.4.jar
cxf-rt-wsdl-3.0.4.jar
cxf-rt-ws-policy-3.0.4.jar
cxf-rt-ws-security-3.0.4.jar
cxf-tools-common-3.0.4.jar

cxf-tools-wsdlto-core-3.0.4.jar
cxf-tools-wsdlto-databinding-jaxb-3.0.4.jar
cxf-tools-wsdlto-frontend-jaxws-3.0.4.jar

为什么我在Tomcat服务器上出现此错误？

我有同样的问题，我花了很长时间才弄明白。有些人还在SO上发布了这个问题：

source code

cxf-failing-with-incompatibleclasschangeerror-exception-on-unit-test

AssertionBuilderRegistry加载失败，因为它是一个接口并扩展了AssertionBuilderFactory，而在较旧版本的neethi库中，AssertionBuilderFactory被定义为具体类。因此抛出了IncompatibleClassChangeError。

关于IncompatibleClassChangeError的原因：

could-not-load-extension-class-org-apache-cxf-ws-policy-assertionbuilderregistry

总之，您需要升级neethi库版本。

grails cxf BeanCreationException
