feat: 프로젝트 목록 조회 / 삭제 API 구현 - #6
Conversation
내가 학습 중인 프로젝트 목록을 생성 순서(오래된 순)로 무한 스크롤 조회한다. 각 항목엔 다음에 풀 문제가 속한 세트 정보, 전체 진행률, 재생 버튼용 nextProblemId가 포함된다. 다음 문제는 가장 최근에 정답 제출한 문제의 다음 순번으로 계산하며, 다 풀었는지와 무관하게 마지막 문제 다음엔 1세트 1번으로 되돌아간다. 문제 생성/풀이 기능이 아직 없어 Problem 문서는 이 계산에 필요한 최소 필드(projectId/setId/order/answeredAt)만 우선 정의했다.
프로젝트를 소프트 삭제(deletedAt)한다. 본인 소유가 아니거나 이미
삭제된 경우 존재 여부를 노출하지 않기 위해 동일하게 404로 응답한다.
"생성 취소" API와 DELETE /projects/{projectId} 경로가 겹쳐서
생성 취소 쪽을 POST /projects/{projectId}/cancel로 옮기기로 함.
Walkthrough프로젝트 목록 조회와 소프트 삭제 기능을 추가했습니다. 프로젝트 및 문제 MongoDB 문서와 저장소를 정의했습니다. 목록 조회는 진행률, 현재 세트, 다음 문제 정보를 반환합니다. 프로젝트 API와 OpenAPI 문서를 추가했습니다. Changes프로젝트 관리 기능
Estimated code review effort: 3 (Moderate) | ~25 minutes Mergeability Score: 🟡 Moderate · up to The new project APIs can return inconsistent pages, expose malformed pagination as server errors while allowing excessive database work, and report success for concurrent deletion requests that should make the second request a 404. These concrete correctness and API-behavior risks should be addressed or explicitly accepted before merging. Possibly related PRs

Spring Framework official documentation method validation @validated controller RequestParam ConstraintViolationException PageRequest.of negative page size
💡 Result:
In the Spring Framework, method validation using @Validated at the controller level or on method parameters allows for the use of Jakarta Bean Validation constraints (such as @Min, @Max, @Size) directly on @RequestParam arguments [1][2]. 1. Method Validation and @Validated: For Spring Framework 6.1 and later, Spring MVC provides built-in support for method validation [1][2]. To leverage this, it is recommended to avoid placing @Validated at the controller class level, as this activates AOP proxy-based validation which can sometimes interfere with Spring MVC's native handler method validation [1][2]. Instead, apply constraints directly to parameters [2]. When validation fails, Spring throws a HandlerMethodValidationException (or a ConstraintViolationException in certain scenarios, such as when using AOP-based validation) [1][2][3]. 2. Handling PageRequest Negative Size: PageRequest.of(int pageNumber, int pageSize) enforces strict boundaries: pageNumber must not be negative, and pageSize must be greater than 0 [4]. Providing invalid values (like a negative page size) directly to PageRequest.of will throw an IllegalArgumentException [4][5][6]. Because PageRequest validation occurs at the constructor level rather than via Jakarta Bean Validation annotations, @Min or @Max applied to a Pageable object will not automatically prevent an IllegalArgumentException from the PageRequest constructor itself. To handle these scenarios: - Validation logic: For pagination parameters, it is best practice to validate the values before invoking PageRequest.of() [6]. - Controller-level handling: If you encounter IllegalArgumentException for pagination, you can handle it globally using a @ControllerAdvice class with an @ExceptionHandler to return a 400 Bad Request status [7]. - Exception Handling for ConstraintViolationException: If using Bean Validation on other parameters, use @ControllerAdvice to catch ConstraintViolationException and map it to a user-friendly response [7]. When using Hibernate/JPA, note that persistence-related constraint violations may be wrapped in a TransactionSystemException, which requires checking the root cause [8].

site:docs.spring.io/spring-framework/reference/web/webmvc/mvc-controller/ann-validation.html HandlerMethodValidationException @ExceptionHandler controller method validation Spring Framework 7
💡 Result:
In the Spring Framework, HandlerMethodValidationException is the exception raised when method-level validation fails [1]. This occurs when @Constraint annotations are applied directly to method parameters or return values, a feature that supersedes individual parameter validation [1]. To handle this exception within an @ExceptionHandler method (typically inside a @ControllerAdvice class or an individual controller), you can catch HandlerMethodValidationException directly [1]. The exception provides structured access to validation errors via a list of ParameterValidationResult objects, which group errors by method parameter [1]. You can process these results in two primary ways: 1. Iteration: You can iterate over the results provided by the exception to extract error details [1]. 2. Visitor Pattern: The exception includes a visit method that allows you to provide a visitor implementation with specific callback methods based on the controller method parameter type (e.g., RequestParam, ModelAttribute, PathVariable) [1]. It is recommended that applications handle both MethodArgumentNotValidException and HandlerMethodValidationException, as either may be raised depending on the controller method signature [1]. While they serve different purposes—MethodArgumentNotValidException targets a single object, while HandlerMethodValidationException covers a list of method parameters—they are designed to be similar and can be handled with nearly identical logic [1]. For simpler use cases, extending ResponseEntityExceptionHandler is often the most efficient approach, as it provides built-in handling for these exceptions [1].

Spring Data MongoDB Sort property "id" @id maps to _id field official documentation
💡 Result:
In Spring Data MongoDB, a property annotated with @Id (org.springframework.data.annotation.Id) is mapped to the MongoDB _id field [1][2]. When defining sort expressions in Spring Data, you should generally use the name of the property as it appears in your Java class, not the underlying database field name [3]. Because the mapping layer handles the translation, using the Java property name (e.g., "id") in your Sort object allows the framework to correctly map it to the _id field [3]. Key points regarding this mapping include: - Automatic Mapping: If you have a field named id (without an @Id annotation), Spring Data also maps it to the _id field by default [1][2]. - Sort Expressions: When using repository methods or Sort objects (e.g., Sort.by("id")), referring to the Java property "id" is the recommended practice [3]. - Aggregation Pipeline: While repository-based sorts are mapped automatically, caution is advised when manually writing aggregation pipelines, where you might need to reference the actual database field name (_id) depending on the context [3]. - Precedence: Explicitly annotated @Id properties take precedence over implicit "id" property naming [4]. If you encounter issues where sorting on "id" does not behave as expected, ensure that no other annotations (like @Field) are conflicting with the @Id mapping, as the framework uses the mapped property name for sorting [3].

고유한 보조 정렬 키를 추가하세요.
createdAt 값이 같은 프로젝트가 있으면 페이지 경계가 안정적이지 않아 문서가 중복되거나 누락될 수 있습니다. createdAt 다음에 고유한 id를 정렬 키로 추가하고, 동일한 createdAt을 가진 프로젝트를 페이지 크기 1로 조회하는 회귀 테스트를 추가하세요.
