   你好，我们这边可能想调用dubbo内置的回声测试接口。但看了一下dubbo.js似乎没办法调用api包之外的接口，想确定一下是否有办法调用回声测试接口。
   
   回声测试用于检测服务是否可用，可以使用启动检查的check配置，也可以从代码中检测，dubbo中的所有服务自动实现EchoService接口，所以可以将任意的服务类型强转为EchoService
   Spring配置
   
   
   <dubbo:reference id="memberService" interface="com.xxx.MemberService" />
   调用代码：
   
   HelloService helloService = ctx.getBean("helloService"); 
   EchoService echoService = (EchoService) helloService; // 强制转型为EchoService
   // 回声测试可用性
   String status = echoService.$echo("OK"); 
   assert(status.equals("OK"));
