使用 CXF 做 webservice 简单例子

• Web 服务标准支持：CXF 支持以下 Web 服务标准：
  • Java API for XML Web Services (JAX-WS)
  • SOAP
  • Web 服务描述语言（Web Services Description Language ，WSDL）
  • 消息传输优化机制（Message Transmission Optimization Mechanism，MTOM）
  • WS-Basic Profile
  • WS-Addressing
  • WS-Policy
  • WS-ReliableMessaging
  • WS-Security
• 前端建模：CXF 提供了前端建模的概念，允许您使用不同的前端 API 来创建 Web 服务。API 允许您使用简单的工厂 Bean 并通过 JAX-WAS 实现来创建 Web 服务。它还允许您创建动态 Web 服务客户端。
• 工具支持：CXF 提供了用于在 Java Bean、Web 服务和 WSDL 之间进行转换的不同工具。它提供了对 Maven 和 Ant 集成的支持，并无缝地支持 Spring 集成。
• RESTful 服务支持：CXF 支持代表性状态传输（Representational State Transfer，RESTful ）服务的概念，并支持 Java 平台的 JAX-RS 实现。（本系列的第 2 部分将提供有关 RESTful 服务的更多信息。）
• 对不同传输和绑定的支持：CXF 支持不同种类的传输，从 XML 到逗号分隔值 (CSV)。除了支持 SOAP 和 HTTP 协议绑定之外，它还支持 Java Architecture for XML Binding (JAXB) 和 AEGIS 数据绑定。
• 对非 XML 绑定的支持：CXF 支持非 XML 绑定，例如 JavaScript Object Notation (JSON) 和 Common Object Request Broker Architecture (CORBA)。它还支持 Java 业务集成（Java Business Integration，JBI）体系架构和服务组件体系架构（Service Component Architecture，SCA）。
• code first 或者 xml first  ： 支持使用code first 或者 xml first 的方式来创建web服务。
