使用 CXF 和 Apache Camel 迁移到 Spring boot 2 的问题

Question

在我的项目中，我们使用的是 Spring Boot 1.5.7、Apache Camel 2.19.3 和 Apache CXF 3.2.1，并且我们对 SOAP 服务没有任何问题。但是当使用 Apache Camel 2.24.1 和 Apache CXF 3.3.2 迁移到 Spring Boot 2.1.3 时，SOAP 服务已经停止工作。

我希望在调用 SOAP 服务时，答案是正确的，就像迁移之前一样。但是，目前出现的错误如下。

这个空指针错误似乎来自您的 cxf 服务的服务器端，因此您应该查看服务的后端。
