Spring boot 使用CXF和Apache Camel迁移到Spring boot 2时出现问题

在我的项目中，我们使用的是SpringBoot1.5.7、ApacheCamel 2.19.3和ApacheCxf3.2.1，SOAP服务没有问题。但是当使用ApacheCamel 2.24.1和ApacheCxf3.3.2迁移到SpringBoot2.1.3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。然而，我现在遇到的错误如下

这个空指针错误似乎来自cxf服务的服务器端，因此您应该查看服务的后端。

尝试查看您自己的源代码，在

m.indra.iacm.adm.adp.jaxws_asm.GetDefaultStepResponse\u WrapperTypeHelper1.createWrapperObject中获取NPE的位置，例如，通过调试或添加日志输出etcAt，我所做的许多测试中的时间就是调试代码。我发现obs是空的。Object o2=helper.createWrapperObject（objs）；我看到了一个重要的区别。在从版本迁移之前，当我进行SOAP调用时，我首先通过我的服务，然后通过WrapperClassOutiterCeptor拦截器。然而，在迁移SOAP调用之后，它从未到达我的服务。拦截器给了我NPE，因为服务的响应是空的。问题是这个拦截器在调用我的服务之前跳转了。这在迁移之前是没有发生过的。
