The configuration item supports the priority,like viper Environment variable > file > default； for example：

type Database struct {
	Host                string `json:",optional,default=127.0.0.1:27017"`
}

config file

Database:
     Host: 127.0.0.1:27011

os.Setenv("Database. Host","127.0.0.2:27011") Then, Database.Host=127.0.0.2:27011，if env is nil,Database.Host=127.0.0.1:27011
