Walkthrough

The file manager now exposes a unified resource endpoint, applies entity-specific access rules, retrieves resources from local or SharePoint storage, and centralizes HTTP response construction. File URLs and related tests now use /api/v1/files/{id}.

Changes

Unified file download flow

Layer / File(s) Summary
Entity-specific access validation
src/main/java/com/itasocialacademy/oitassist/filemanager/access/FileAccessValidator.java, src/main/java/com/itasocialacademy/oitassist/filemanager/validation/resolvers/FileAccessValidatorResolver.java, src/main/java/com/itasocialacademy/oitassist/news/service/validation/NewsFileAccessValidator.java, src/main/java/com/itasocialacademy/oitassist/news/package-info.java
Validators now select access rules by RelatedEntityType. NEWS access supports published content, privileged roles, and author ownership.
Storage resource retrieval
src/main/java/com/itasocialacademy/oitassist/filemanager/providers/interfaces/StorageProvider.java, src/main/java/com/itasocialacademy/oitassist/filemanager/providers/LocalStorageProvider.java, src/main/java/com/itasocialacademy/oitassist/filemanager/providers/SharePointStorageProvider.java
Storage providers now return Spring Resource objects instead of provider URLs. Local paths and SharePoint retrieval failures map to explicit exceptions.
Service download orchestration
src/main/java/com/itasocialacademy/oitassist/filemanager/dto/response/FileResourceDto.java, src/main/java/com/itasocialacademy/oitassist/filemanager/service/interfaces/FileService.java, src/main/java/com/itasocialacademy/oitassist/filemanager/service/FileServiceImpl.java, src/test/java/com/itasocialacademy/oitassist/filemanager/service/FileServiceImplTest.java
The service authorizes temporary and attached files, retrieves resources, selects display filenames, and generates unified file URLs. Tests cover authorization, resource retrieval, metadata, and URL changes.
Download endpoint and response rendering
src/main/java/com/itasocialacademy/oitassist/filemanager/controller/FileController.java, src/main/java/com/itasocialacademy/oitassist/filemanager/web/FileResourceResponseFactory.java, src/main/java/com/itasocialacademy/oitassist/security/config/SecurityConfig.java, src/test/java/com/itasocialacademy/oitassist/filemanager/controller/FileControllerTest.java
GET /api/v1/files/{id} delegates response construction to a factory. The factory resolves MIME types, content disposition, filenames, content length, and nosniff. Controller tests use the new endpoint and service contract.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 8d316

The updated request binding may fail to populate the intended role value because the annotation is not effective for Spring MVC, which could cause role updates to use a missing or incorrect value; merge is reasonable with explicit owner confirmation of the request contract. The remaining documentation issue is localized.

Reuse ROLE_ADMIN.

Line 543 duplicates the ROLE_ADMIN value. Replace "ADMIN" with ROLE_ADMIN. SonarCloud reports this duplication.

Proposed fix
-        boolean isAdmin = securityFacade.hasRole("ADMIN") || securityFacade.hasRole("ORG");
+        boolean isAdmin = securityFacade.hasRole(ROLE_ADMIN) || securityFacade.hasRole("ORG");

Prevent inline rendering of client-controlled MIME types. The policies reject .html and .svg, but validation checks only the filename extension. FileServiceImpl persists MultipartFile.getContentType() unchanged, and published news files are accessible to guests; an allowed .png filename with HTML bytes and text/html can therefore be returned as inline application-origin content. Validate file signatures and derive the MIME type server-side, or use ContentDisposition.attachment() for uploaded files.

734-736: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Consider sharing the download path literal with the controller.

buildDownloadUrl hardcodes /api/v1/files/download/. FileController declares the same path in @RequestMapping("/api/v1/files") plus @GetMapping("/download/{id}"). If either mapping changes, every DTO URL returned by upload and listing operations points to a dead endpoint, and no test detects the mismatch because the tests assert the same literal.

A shared constant, or MvcUriComponentsBuilder.fromMethodName(FileController.class, "downloadFile", id), keeps both sides aligned. The centralization of URL building in one private method is a good improvement over the previous per-provider approach.

305-309: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider returning the missing-content failure outside the try block.

The FileListingException thrown here is caught by the catch (Exception e) block at Line 319. The caller still receives a FileListingException, so behavior is unchanged. However, the known "content is null" condition is logged as "Unexpected error while streaming file from SharePoint", which makes debugging harder.

Rethrowing the known condition before the generic handler keeps the log accurate. Nice work mapping 404 to a dedicated exception, by the way.

♻️ Proposed refactor

Use a Spring MVC binding annotation.

com.azure.core.annotation.QueryParam has no effect on this Spring MVC handler. The current UpdateFileRoleRequestDto.newRole property matches the "newRole" query parameter, so binding succeeds. Replace it with @ModelAttribute to state the intended contract explicitly.

724-738: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Add coverage for an authorized non-owner.

The new branch returns storedFilename for an authorized non-owner. The added test at Line 1478 covers only the owner branch. Add a test with a different authenticated user and assert that FileDownloadDto.displayFilename() returns storedFilename.

73-73: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Describe entityId as the source entity.

detachFiles removes files from the entity identified by entityId. The surrounding Javadoc uses “from,” but this changed line says “to,” which reverses the contract and can mislead callers.

Proposed fix
-     * `@param` entityId   the ID of the entity to detach files to
+     * `@param` entityId   the ID of the entity to detach files from
