Field annotated with @Value is returning null

I am using ConstraintValidator implementation to validate if character is above certain height defined in application.properties and I have encountered a problem where the field minimumHeight with @Value is always null. I have also tried constructor injection but then it gives out error as follows:

java.lang.NoSuchMethodException: com.miquido.Validator.CharacterValidator.<init>()
at java.base/java.lang.Class.getConstructor0(Class.java:3585) ~[na:na]
at java.base/java.lang.Class.getConstructor(Class.java:2271) ~[na:na]
at org.hibernate.validator.internal.util.privilegedactions.NewInstance.run(NewInstance.java:41) ~[hibernate-validator-6.2.3.Final.jar:6.2.3.Final]

This is my validator:

import org.springframework.beans.factory.annotation.Value;

import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;


public class CharacterValidator implements ConstraintValidator<ValidCharacter, Long> {

    @Autowired
    private ConfigProperties configProperties;

    @Override
    public void initialize(ValidCharacter constraintAnnotation) {
        ConstraintValidator.super.initialize(constraintAnnotation);
    }

    @Override
    public boolean isValid(Long value, ConstraintValidatorContext context) {
        configProperties = SpringApplicationContextService.getApplicationContext().getBean(ConfigProperties.class);
        if (value == null) {
            return true;
        }
        formatMessage(context);
        return value >= configProperties.getMinimum();
    }

    private void formatMessage(ConstraintValidatorContext context) {
        String msg = context.getDefaultConstraintMessageTemplate();
        String formattedMsg = String.format(msg, configProperties.getMinimum());
        context.disableDefaultConstraintViolation();
        context.buildConstraintViolationWithTemplate(formattedMsg)
                .addConstraintViolation();
    }
}

    @Target({ElementType.FIELD})
    @Retention(RetentionPolicy.RUNTIME)
    @Constraint(validatedBy = CharacterValidator.class)
    public @interface ValidCharacter {
    
        String message() default "Character must be higher than %s";
    
        Class<?>[] groups() default {};
    
        Class<? extends Payload>[] payload() default {};
    }

EDIT 1 I have edited my code as @antey13 suggested, but still the minimumHeight is null.

EDIT 2 I have added SpringApplicationContextService with static getter that returns ApplicationContext and I inject the bean manually in implementantion of ConstraintValidator.

@Service
public class SpringApplicationContextService implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringApplicationContextService.applicationContext = applicationContext;
    }
}
