How to set @value property java

Question

I was writing pact provider test which validate the incoming request from consumer and i have used custom constraint validator for that like

public class MaxRecipients implements
    ConstraintValidator<MaxRecipientsSize, Collection> {

  @Value("${recipient.max.size}")
  private Integer recipientMaxSize;


  @Override
  public void initialize(MaxRecipientsSize constraintAnnotation) {
  }

  @Override
  public boolean isValid(Collection value, ConstraintValidatorContext cvc) {
    if (isEmpty(value)) {
      return TRUE;
    }

Here when control comes, the value of recipientMaxSize becomes null, i have configured the property in application properties and property source. Can someone help on this?

Does this answer your question? [Spring value injection unable to get value from properties](https://stackoverflow.com/questions/48545498/spring-value-injection-unable-to-get-value-from-properties) — Deepak Kumar, Sep 07 '20 at 14:29
You also need to pass properties into test class. For example using `@TestPropertySource`. More details here https://www.baeldung.com/spring-test-property-source — Nikolai Shevchenko, Sep 07 '20 at 14:30
I have already registered it using property source and it shows the value when used in test class but when the control goes to service level, it shows the value as null — Usf Shilpa, Sep 07 '20 at 14:38

I think your class MaxRecipients lacks the annotation @Component or similar. Because of that, @Value is not filled through Spring.

i have used @component also – Usf Shilpa Sep 07 '20 at 14:45
Then your applications.properties / application.yml is not loaded properly. Please add your complete code (including @Component) and your application.properties/yml – Milgo Sep 07 '20 at 15:13
