restlet jax-rs配置
?
配置基于 RESTlet JAX-RS Extension 的 Web Service 也就是部署该架构下的 Web Service。RESTlet 架构提供两种部署 Web Service 的方式。两种方式都方便简单，用户可以根据自己的需求选择任意一种部署方式。
将 Web Service 当做单独的 Java 程序进行部署将 Web Service 部署到 Servelet Container 中两种方式都方便简单，用户可以根据自己的需求选择任意一种部署方式。
将 Web Service 部署成一个单独运行的 Java 应用非常的简单，只需要完成以下几个步骤。
导入需要的 JAR 包，org.restlet.jar，以及org.restlet.ext.jaxrs_1.0.jar。为 HTTP Server 创建相应 Java 类。在新建的 Java 类中依次完成以下工作，引入 org.restlet.jar 包中需要的类，新建 HTTP Server，定义该 Server 监听的端口，将 Web Service 的配置类加入到 HTTP 服务器中。编译运行 HTTP Server。将基于 RESTlet Jax-Rs Extension 的 Web Service 部署到 Servelet Container 中的过程和部署一个基本的 Servelet 极其相似。不同的是，部署过程中，用户需要注意添加需要的 Jar 包。以下 Jar 是该部署方式所需要的。
org.restlet.jarorg.restlet.ext.jaxrs_1.0.jarcom.noelios.restlet.jarcom.noelios.restlet.ext.servlet_2.5.jar为了成功将基于 RESTlet Jax-Rs Extension 的 Web Service 部署为 Servelet，用户需要完成以下动作。
编译基于 RESTlet Jax-Rs Extension 的 Web Service 包含的代码。将需要的 JAR 包存放于 /WEB-INF/lib 中。创建 Servelet 的配置文件 web.xml。将所有相关内容打包成 WAR 包，并部署到用户选定的 Servelet 容器中。?

@GET
@Path("usergroup/{id}")
public String findUserGroup(@PathParam("id") String id){
UserGroup group = UserGroupManager.get().getDetails(id);
if(group != null)
return group.toString();
else
return "The group you queried(ID:" + id + ") doesn't existed!";
}

@path指定资源的路由,可以有资源的路由和资源方法的路由。
@GET指定请求的类型（get,put,post,delete)
@PathParam与@path中的参数对应
