[bug] It's a Bug when Zero value equals to the value I set

[xiaofeige]

Reproducible Example

config example:

var Config struct {
	AuthSettings struct {
		LwpNoAuth bool `required:"true" default:"true"`
	}
}

It doesn't work When I set LwpNoAuth to false, because you check blank in this way, see the picture below.

The value will always be true even if I set it to false.
