springboot 整合 CXF 版本異常 java.lang.NoClassDefFoundError:ServletRegistrationBean

在使用SpringBoot 項目整合webservice組件 CXF的時候，在啓動時，拋出異常以下，查閱資料初步判斷爲版本問題。升級到高版本後正常啓動。

cxf 剛開始使用版本  3.1.7 後更新爲 3.2.5 。

參考借鑑：

spring boot 1.4 版本對應cxf-spring-boot-starter-jaxws   3.1.X  版本

spring boot 1.5 版本對應cxf-spring-boot-starter-jaxws   3.2.X  版本
