服务的降级自定义异常类出现spring cloud Feign ： java.util.concurrent.TimeoutException: null

异常信息：

解决方法：
在对应的方法上加上@HystrixCommand(commandProperties = {@HystrixProperty(name =“execution.isolation.thread.timeoutInMilliseconds” ,value =“3000” )})，特别是(commandProperties = {@HystrixProperty(name =“execution.isolation.thread.timeoutInMilliseconds” ,value =“3000” )})这个后缀，不加不走你的自定义方法
