I submitted a question on stack flow, I hope someone can help me solve my doubts, why should I let go of the empty string check，thank

My question is why the empty string can pass the required check. If I don’t want the empty string to pass the check, how should I configure it in the annotation?

An empty string means the attribute is there but has no value, the required here means that it has to be present. It doesn't mean it has to have a value, those are 2 different things. If you want a non empty value add an @NotEmpty or @NotBlank for the validation.
