src/main/java/org/festimate/team/domain/matching/validator/MatchingValidator.java (1)
34-38: Minor: Null-safety guard
matching.getFestival()ormatching.getFestival().getFestivalId()can be null for corrupt data.
Consider short-circuiting to avoidNullPointerException:if (matching.getFestival() == null || !Objects.equals(matching.getFestival().getFestivalId(), festival.getFestivalId())) { throw new FestimateException(ResponseError.FORBIDDEN_RESOURCE); }src/main/java/org/festimate/team/domain/matching/service/impl/MatchingServiceImpl.java (2)
30-31: Wildcard static import hurts traceability
import static …MatchingValidator.*;obscures the origin of static calls.
Import only the used methods (isMatchingDateValid,isFestivalMatchValid,isApplicantParticipantValid) for readability.
90-96:findBestCandidateByPriorityopens a read/write transaction unnecessarilyThe method only performs
SELECTs; yet the explicit@Transactionalhere overrides the class-levelreadOnly=true, creating a read-write transaction.- @Transactional + @Transactional(readOnly = true)This avoids superfluous flush checks and improves performance.
src/test/java/org/festimate/team/domain/matching/service/impl/MatchingServiceImplTest.java (1)
276-306: Assertion couples to message string – prefer enum check
hasMessage(ResponseError.FORBIDDEN_RESOURCE.getMessage())ties the test to text that may change during localisation.
Use the enum itself:assertThatThrownBy(() -> ...) .isInstanceOf(FestimateException.class) .extracting("error") // assuming FestimateException exposes the enum .isEqualTo(ResponseError.FORBIDDEN_RESOURCE);Reduces brittle tests.

Participant comparison uses reference equality – will fail with detached/rehydrated entities
matching.getApplicantParticipant() != participant compares object references, not logical identity.
In a Hibernate/JPA context the same DB row can be represented by different Java instances (e.g., proxy ≠ DTO), causing a legitimate request to be rejected.
-import org.festimate.team.domain.participant.entity.Participant;
+import org.festimate.team.domain.participant.entity.Participant;
+import java.util.Objects;
…
- if (matching.getApplicantParticipant() != participant) {
+ if (!Objects.equals(
+ matching.getApplicantParticipant().getParticipantId(),
+ participant.getParticipantId())) {
throw new FestimateException(ResponseError.FORBIDDEN_RESOURCE);
}Compare by participantId (or equals) to avoid false negatives.

In
src/main/java/org/festimate/team/domain/matching/validator/MatchingValidator.java
around lines 28 to 32, the participant comparison uses reference equality which
can fail for detached or rehydrated entities. Replace the reference comparison
with a logical identity check by comparing participant IDs or using the equals
method to ensure correct validation of participant identity.
