我是否可以创建没有到验证器实现链接的spring mvc自定义验证注释？

@Target({ElementType.FIELD, ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
public @interface CustomValidation {
    String message() default "Invalid value";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

public class CustomValidator implements ConstraintValidator<CustomValidation, String> {
    @Override
    public void initialize(CustomValidation customValidation) {
    }
    
    @Override
    public boolean isValid(String value, ConstraintValidatorContext context) {
        // 自定义验证逻辑
        return value != null && value.startsWith("abc");
    }
}

public class UserController {
    @PostMapping("/user")
    public ResponseEntity<String> createUser(@CustomValidation String username) {
        // 处理逻辑
        return ResponseEntity.ok("User created successfully");
    }
}
