// 有以下两种创建Client实例的方式
// 方式一
ClientConfig cc = new DefaultClientConfig();
cc.getProperties().put(ClientConfig.PROPERTY_CONNECT_TIMEOUT, 10*1000);
// Client实例很消耗系统资源，需要重用
// 创建web资源，创建请求，接受响应都是线程安全的
// 所以Client实例和WebResource实例可以在多个线程间安全的共享
Client client = Client.create(cc);
// 方式二
// Client client = Client.create();
// client.setConnectTimeout(10*1000);
// client.getProperties().put(ClientConfig.PROPERTY_CONNECT_TIMEOUT, 10*1000);
// WebResource将会继承Client中timeout的配置
// WebResource resource = client.resource("http://127.0.0.1:10000/service/sean?desc=description");

// String str = resource
