   如果你没有定制过Java-Chassis的异常转换机制的话, 
那么下游服务的原始异常信息应该是在`org.apache.servicecomb.swagger.invocation.exception.DefaultExceptionToProducerResponseConverter`
 类中打印出来的. 该类型是Java-Chassis提供的默认异常转换类, 
业务代码抛出的异常会被Java-Chassis框架捕获并交给`DefaultExceptionToProducerResponseConverter`转换成490或590异常.
   
   至于具体是什么日志, 这得看你怎么配置你的日志打印框架了.
