起步
参照这一系列的另外一篇文章：
Apache CXF实现Web Service（2）——不借助重量级Web容器和Spring实现一个纯的JAX-RS(RESTful) web service
首先在eclipse中新建一个Dynamic Web Project，然后实现上篇文章中的所有类，唯一不同的是这里，我们不需要一个Server.java来启动一个Web Service。我们用CXF自带的org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet来在容器中启动一个Web Service服务。

可以发现我们使用了org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet这个Servlet包括使用里面一些启动参数：
jaxrs.serviceClasses
jaxrs.providers
来配置RESTful Web Service，其参数与我们上篇文章中用代码JAXRSServerFactoryBean的参数设置一致。
启动测试
我们在Eclipse中，将Web项目在Tomcat中运行
Tomcat运行Run As... -> Run on Server
最后
我们用浏览器访问Tomcat默认的8080端口地址：http://localhost:8080/cxf/services/roomservice/room
补充 Servlet配置参数模板
（注意：这只是一个模板，需要修改相关参数，请勿直接复制粘贴到项目中）
