Apache CXF 介绍
 
Apache CXF 是一个开源的项目，前身是XFire与Celtix结合的产物，它是一个高性能的WebService，同时还支持多种绑定。
 
CXF比较适合创建各种不同传输协议的服务。一般的服务总线是以集成各种服务为目的，CXF相反，它是以提供各种服务为目的的。
 
与Apache Axis2相比，CXF全都是有优点了。这里就不说了，很多这类对比的文章。
 
CXF所支持的主要功能如下：
支持多种绑定方式：SOAP、REST、Corba
支持的Web服务包括：WS-Addressing、WS-Security、WS-ReliableMessaging和WS-Policy
支持多种传输协议
可插拔式的数据绑定
前端核心程序的清晰分离
高性能
 
CXF的架构体系主要包括下面部分:
CXF总线
消息和拦截器
前端，通过JAX-WS创建服务，可以从不同的源头（Java类、WSDL1.1/2.0）来创建服务
传输层
服务模型（在CXF内代表服务）
绑定
