自定义注释未在requestObject春季启动时调用

Question

在请求POJO上使用自定义验证批注时，它没有执行约束所要求的检查。

当我直接从控制器调用验证器时，它将起作用。软件包处于组件扫描状态，因为同一软件包中的其他类是在春季注入的。

@Documented
@Constraint(validatedBy = Validator.class)
@Target({ElementType.TYPE, ElementType.ANNOTATION_TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Qualifier
public @interface ValidRequest{
    String message() default "";

    Class<?>[] groups() default { };

    Class<? extends Payload>[] payload() default { };
}


@Component
public class Validator implements ConstraintValidator<ValidRequest,Request> 
{

    @Override
    public void initialize(ValidRequest valid) {
    }

    @Override
    public boolean isValid(){
    //validation logic here
    }
}    
//Annotation applied on request object
@ValidRequest
public class Request{

} 


I expect isValidMethod should be called when I receive the Request in controller. It's not getting called.
