答案 0 :(得分：0)
我不明白为什么会这样，因此决定发布第二次验证。最后，一切都按预期进行。为什么Spring多次验证我不了解，但我认为这段代码在实现方面非常有效。
class ValidatorUniqueLogin : ConstraintValidator<UniqueLogin, String> {
@Autowired val serviceAccaunt: ServiceAccaunt? = null
override fun initialize(annotation: UniqueLogin?) {}
override fun isValid(login: String, ctx: ConstraintValidatorContext): Boolean {
return if (serviceAccaunt!= null) !(serviceAccaunt.isHaveLogin(login)) else true
}
}
