Apache CXF简介

CXF目前是 apache下面的一个顶级开源项目， CXF是从 Celtix和 XFire两个项目合并而得到的一个新项目。

早先 CXF是 apache下面的一个孵化项目，在 08年的时候升级成为了顶级项目。 CXF主要实现了 JAX-WS和 JAX-RS两个协议 API，并且支持 SOAP, XML/HTTP, RESTful HTTP, CORBA协议绑定，并且可以通过 HTTP, JMS, JBI进行传输。

CXF包含一系列特性，其中最主要的特性包括

1. 对 web service规范的支持， CXF supports a variety of web service standards including SOAP, the WS-I Basic Profile, WSDL, WS-Addressing, WS-Policy, WS-ReliableMessaging, WS-Security, WS-SecurityPolicy, WS-SecureConverstation, and WS-Trust (partial).

2. 前端， CXF支持很多前端开发模型

 

CXF支持 contract first(wsdl first)和 code first(java first)两种开发模式。
