   我想请教一个问题
   服务提供者 地址有一个 List<Instance>，这个我有办法拿到
   
   我希望，我本次调用，我自己指定调用其中的一个 Instence
   
   
   问，如何指定？？？

   可以看看 [Endpoint参数](https://servicecomb.apache.org/references/java-chassis/zh_CN/build-provider/context-param.html)

   文档地址不对
   
   https://servicecomb.apache.org/references/java-chassis/zh_CN/general-development/context.html#context-discoverytree
   
   应该是这个：
   案例： 使用 Context 和 DiscoveryTree 实现轮询调用一个微服务的所有实例
   
   
   ```java
   
     interface DateTimeSchemaWithContextInf {
       Date getDate(InvocationContext context, Date date);
     }
   
     @RpcReference(microserviceName = "springmvc", schemaId = "DateTimeSchema")
     private DateTimeSchemaWithContextInf dateTimeSchemaWithContextInf;
   
     // code slip
     for (String endpoint : enpoints) {
       InvocationContext invocationContext = new InvocationContext();
       invocationContext.addLocalContext(LoadbalanceHandler.SERVICECOMB_SERVER_ENDPOINT, parseEndpoint(endpoint));
       Date date = new Date();
       TestMgr.check(date.getTime(), dateTimeSchemaWithContextInf.getDate(invocationContext, date).getTime());
     }
   
     // code slip
     private Endpoint parseEndpoint(String endpointUri) throws Exception {
       URI formatUri = new URI(endpointUri);
       Transport transport = SCBEngine.getInstance().getTransportManager().findTransport(formatUri.getScheme());
       return new Endpoint(transport, endpointUri);
     }
   
   ```
