CXF应用程序开发 WS

OpenSource中关于CXF的简介：Apache CXF一个开源的Service框架，它实现了JCP与Web Service中一些重要标准。CXF简化了构造，集成，面向服务架构(SOA)业务组件与技术的灵活复用。在CXF中，Service使用WSDL标准定义并能够使用各种不同的消息格式(或binding)和网络协议(transports)包括SOAP、XML（通过HTTP或JMS）进行访问。CXF同样支持多种model 如：JAX-WS，JBI，SCA和CORBA service。CXF设计成可灵活部署到各种容器中包括Spring-based，JBI，SCA， Servlet和J2EE容器。

       用CXF构建webservice程序的大致流程如下：

       1 配置web.xml文件，加载CXF

       2 编写java接口，和接口的实现

       3 在spring的applicationContext.xml中配置java文件

       4 创建beans.xml文件，里面配置接口的实现类

      5 运行tomca服务器即可生成wsdl文件

      6 编写测试代码：编写java测试文件和client-beans.xml文件

      7编写运行客户端文件所需的服务器，可以单独编写，也可以在随tomcat启动

示例代码。首先下载cxf，然后解压，将lib下的所有jar包拷到工程下面
