我正在使用 CXF 3.0 创建一个宁静的 Web 服务。我的 web 服务工作正常，但我的 cxf 客户端抛出了如下所示的异常

    [qtp392289808-96] WARN org.apache.cxf.phase.PhaseInterceptorChain - Interceptor for {http://localhost:8080/userdetailservice}WebClient has thrown exception, unwinding now

下面是我的代码：

@Resource(name = "cxfWebClient")
    private WebClient restClient;

private UserDetail processCredentials(UserAuthenticationRequest userData)
            throws AuthenticationException {
    try {
        LOGGER.debug("About to authenticate the user {1}",
                userData.getUsername());
        addCommonAttributes(WebConstants.AUTHENTICATE_URL);
        LOGGER.info("About to make a restful call to the userDetailService for user {}", userData.getUsername());
        Response response = restClient.post(userData);
        LOGGER.info("Got the response back from userDetailService");
        UserDetail authenticatedData = response
                .readEntity(UserDetail.class);
        if (authenticatedData == null
                || authenticatedData.getUsername() == null) {
            throw new SellServiceException(
                    StatusCodes.AUTHENTICATION_ERROR_CODE);
        }
        return authenticatedData;
    } catch (RuntimeException ex) {
        LOGGER.error("Error in the processCredentials()", ex);
        throw new SellServiceException(
                StatusCodes.AUTHENTICATION_ERROR_CODE);
    }

}

private void addCommonAttributes(String url) {
        restClient.path(url);
        restClient.accept(MediaType.APPLICATION_JSON).type(
                MediaType.APPLICATION_XML);

    }

    </dependency>

我想我错过了一个重要的 Maven 依赖项，但不确定是哪个。任何人都可以在这方面帮助我吗？

经过一番努力，我能够实施解决方案。解决方法是在cxfWebClient中配置JacksonJaxbJsonProvider，如下图：

<beans:bean id="myJsonProvider"
    class="com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider">
</beans:bean>

<util:list id="webClientProviders">
    <beans:ref bean="myJsonProvider" />
</util:list>
<beans:bean id="cxfWebClient" class="org.apache.cxf.jaxrs.client.WebClient"
        factory-method="create">
        <beans:constructor-arg type="java.lang.String"
            value="${userDetailService.base.url}" />
        <beans:constructor-arg ref="webClientProviders" />
    </beans:bean>
