异常处理：com.alibaba.dubbo.rpc.RpcException

异常处理：com.alibaba.dubbo.rpc.RpcException

1.当出现“com.alibaba.dubbo.rpc.RpcException: No provider available from registry 127.0.0.1:2181 for service com.itheima.service.CheckGroupService on consumer 192.168.0.110 use dubbo version 2.6.0, may be providers disabled or not registered ?”

我的错因：

@Service(interfaceClass=SetmealServiceImpl.class)
@Transactional
public class SetmealServiceImpl implements SetmealService {----------
}

修改后：

@Service(interfaceClass=SetmealService.class)
@Transactional
public class SetmealServiceImpl implements SetmealService {----------
}

原因是：@Service中应该使用interfaceClass=XXX.class指出服务层的规范接口声明方式。而SetmealService是对应的接口，而SetmealServiceImpl是接口的实现类。
