📝 Walkthrough

Walkthrough

Added Spring Boot validation starter dependency; introduced comment request/response DTO records with Jakarta Bean Validation annotations; removed cascade delete on Comment entity relationships; and added EntityGraph annotations to Comment repository query methods.

Changes

Cohort / File(s)	Summary
Maven Dependency pom.xml	Added org.springframework.boot:spring-boot-starter-validation to enable Spring Boot validation support.
Comment Request DTOs src/main/java/org/example/vet1177/dto/request/comment/CreateCommentRequest.java, src/main/java/org/example/vet1177/dto/request/comment/UpdateCommentRequest.java	Added CreateCommentRequest(UUID recordId, String body) and UpdateCommentRequest(String body) records with Jakarta Bean Validation annotations (@NotNull, @NotBlank, @Size) and Swedish messages.
Comment Response DTO src/main/java/org/example/vet1177/dto/response/comment/CommentResponse.java	Added CommentResponse record with fields (id, recordId, authorId, authorName, body, createdAt, updatedAt) and a static from(Comment) factory mapping entity → DTO including nested relations.
Comment Entity src/main/java/org/example/vet1177/entities/Comment.java	Removed cascade = CascadeType.REMOVE from @ManyToOne associations (medicalRecord, author); retained fetch = FetchType.LAZY.
Comment Repository src/main/java/org/example/vet1177/repository/CommentRepository.java	Added @EntityGraph(attributePaths = {"medicalRecord", "author"}) to findByMedicalRecordIdOrderByCreatedAtAsc(UUID) and findByAuthorId(UUID) to load associated entities with queries.

Poem

🐰 I hopped through code with careful paws,
DTOs in hand and validation laws,
No cascade leaps, relations stay neat,
Entity graphs fetch friends we meet,
A tiny change, but tidy and sweet.

Linked Issues check	✅ Passed	The PR successfully implements the Comment DTO requirement from issue #25: CreateCommentRequest and UpdateCommentRequest with validation annotations, CommentResponse for responses, and supporting infrastructure updates.
Out of Scope Changes check	✅ Passed	All changes directly support the Comment DTO implementation: validation framework update, repository optimization with EntityGraph, and cascade removal fix are all necessary infrastructure for proper DTO and entity handling.
