Apache Camel 在调用 CXF Endpoint 时返回 NullPointerException将骆驼从 2.X 升级到 3.0

问题描述

我有一个如下的 CXFEndpoint

        CxfEndpoint cxfEndpoint =new CxfEndpoint();
        cxfEndpoint.setAddress("http://localhost:9201/mock");
        cxfEndpoint.setDataFormat(DataFormat.CXF_MESSAGE);
        cxfEndpoint.setWsdlURL(serviceSoapOutboundWsdl);
        cxfEndpoint.setContinuationTimeout(continutionTimeout);
        cxfEndpoint.getoutFaultInterceptors().add(postOutFaultInterceptor);
        .....
        .....
        exchange.setProperty("cxfEndpoint",cxfEndpoint);

我从我的路由构建器调用这个端点，如下所示 .toD("${exchangeProperty.cxfEndpoint}")

我收到以下异常

向 Receiver:::org.apache.camel.FailedToCreateProducerException 发送出站消息时发生异常：无法为端点创建生产者：http://localhost:9201/mock。原因：java.lang.NullPointerException

将camel 从2.X 升级到3.0 后，我收到此错误。任何解决此问题的意见将不胜感激。
