springboot 整合 CXF 版本异常 java.lang.NoClassDefFoundError:ServletRegistrationBean

在使用SpringBoot 项目整合webservice组件 CXF的时候，在启动时，抛出异常如下，查阅资料初步判断为版本问题。升级到高版本后正常启动。

cxf 刚开始使用版本  3.1.7 后更新为 3.2.5 。

参考借鉴：

spring boot 1.4 版本对应cxf-spring-boot-starter-jaxws   3.1.X  版本

spring boot 1.5 版本对应cxf-spring-boot-starter-jaxws   3.2.X  版本
