本文详细介绍了如何在Karaf中加载并使用CXF-RS进行REST服务集成，以及如何引入AriesBlueprint解决开发环境问题，并提供了一个简单的REST服务实现案例。

先讲一下我是如何一步一步加载cxf-rs的包的，过程比较坎坷啊。

首先，下载最新的karaf，apache-karaf-2.3.2，解包后，运行，在console输入features:addurl http://repo1.maven.org/maven2/org/apache/cxf/karaf/apache-cxf/2.7.5/apache-cxf-2.7.5-features.xml,然后输入features:list,

karaf@root> features:list

[uninstalled] [2.7.5          ] cxf-bindings-object           cxf-2.7.5

可以看到很多feature，我这里只想安装cxf对rest的支持，所以console下输入features：install cxf-jaxrs。安装成功后，打开浏览器输入http:localhost:8181/cxf，会看到提示信息，如果不成功，则报404错误。

2.引入aries blueprint

aries的blueprint在我的开发环境一直有问题，我现在对比karaf，把相关的jar包全部引入了，下面是pom文件：

        </dependency>

有几个问题需要注意一下：

1.查看cxf-rt-transports-http包里面，发现有一个blueprint的注册文件，我们所访问的http://localhost:8181/cxf这个地址的servlet，就是通过这个xml文件注册的，这个包依赖于felix的configadmin ，我当时一直没有弄好，就是因为这个bundle没有加入。

2.cxf-rt-transports-http-jetty 这个包我注释掉，暂时还没什么影响。

下面我参考http://maksim.sorokin.dk/it/2011/07/21/maven-apache-felix-cxf-creating-a-restful-webservice-with-cxf-a-simple-string-example/做一个rest的例子，很简单的例子，一个接口，一个实现。此时不要按照例子讲的那样编码去注册，而是建立一个blueprint文件，由aries帮你自动完成注册。

好了，工作完成了，打包，发布，然后启动容器，访问 http://localhost:8080/cxf ：显示下图：

此时，说明你的rest服务已经注册好了，这个时候再输入http://localhost:8080/cxf/crm/myService/sayHello/world，显示：

最后需要说明的是，通过这种方式，我可以在其它的bundle里面声明rest服务，然后加入blueprint文件，就可以自动完成rest服务的发布了。根本不需要建web工程，加入CxfServlet，以及对spring的依赖，哈哈，是不是很方便啊。

另外，对ws的支持，应该也是同理。
