Description
Set
zeroFields=true
when usingviper.Unmarshal
to override the default configs of slice/map.Motivation and Context
Every component has a default configuration when registering to the factory. When unmarshalling the configuration file to the struct, the slices/maps in the configuration and the default one are merged which is not what we expected. This PR adds the option
zeroFields=true
toviper.Unmarshal
for overriding the default configs of slice/map.How Has This Been Tested?
