hystrix filter initHystrixConfigProvider incorrect

[seasidesky]

What happened:
https://github.com/apache/dubbo-go/blob/master/filter/filter_impl/hystrix_filter.go#L237

filterConfig := config.GetConsumerConfig().FilterConf.(map[interface{}]interface{})[HYSTRIX]

there is a misuse of config.GetConsumerConfig()

What you expected to happen:
https://github.com/apache/dubbo-go/blob/master/filter/filter_impl/hystrix_filter.go#L237
is expected to like this

filterConfig := config.GetProviderConfig().FilterConf.(map[interface{}]interface{})[HYSTRIX]

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

Hi，Hystrix is a fuse solution. As we know, fuses are defined on the consumer side, because fusing is an active protection from the perspective of the client.

I got it, but https://github.com/apache/dubbo-go/blob/master/filter/filter_impl/hystrix_filter.go#L234 and https://github.com/apache/dubbo-go/blob/master/filter/filter_impl/hystrix_filter.go#L237 is a little confusing.

as https://github.com/apache/dubbo-go/blob/master/filter/filter_impl/hystrix_filter.go#L234

if config.GetProviderConfig().FilterConf == nil

while https://github.com/apache/dubbo-go/blob/master/filter/filter_impl/hystrix_filter.go#L237

filterConfig := config.GetConsumerConfig().FilterConf.(map[interface{}]interface{})[HYSTRIX]]

@seasidesky Thank you for mention this. Yes, this is a known bug. Will be fixed this weekend and included in the next release at about mid September. #710
