-对于Java包，更推荐使用Maven工具安装管理。
参照以下代码示例，更新最新版本，在Maven中直接引用即可，并且请在settings.xml中引入有赞云maven仓库。

【说明】

-SDK使用的是OkHttp3，已经暴露了对应的配置方法，可自行根据业务进行配置，参考如下示例。


         OkHttpClient.Builder builder = new OkHttpClient.Builder().readTimeout(5, TimeUnit.HOURS);  
         HttpConfig httpConfig = HttpConfig.builder().OkHttpClientBuilder(builder).build();   
         YouZanClient youZanClient = new DefaultYZClient(httpConfig);
-Java open SDK依赖包引入示例如下。
