If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/zfile-dev/zfile shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

ZFile is a self-hosted unified cloud storage management system written in Java Spring Boot 3.3.2 that aggregates multiple storage backends (S3, OneDrive, SharePoint, Google Drive, local storage, FTP, SFTP) into a single web interface. It enables individuals and small teams to browse, preview (images, video, audio, PDF, Office, 3D models), upload/download files, and generate expiring direct links across all connected storage sources without logging into each service separately. Monolithic Spring Boot 3 application with vertical layering: src/main/java/im/zhaojun/zfile/core/ contains cross-cutting concerns (annotations like @ApiLimit, @DemoDisable, aspects like ApiLimitAspect, cache management via ZFileCacheManager, config beans for datasource/Jackson/Knife4j documentation). Frontend assets likely in src/main/resources/. Deployment uses Dockerfile and shell scripts in .package/script/ (start.sh, stop.sh, restart.sh, status.sh).

Self-hosted cloud administrators, small teams, and individual users who manage files across multiple cloud providers and want a unified, privacy-respecting web interface instead of juggling separate login credentials. Contributors include Java/Spring Boot developers and DevOps engineers interested in multi-storage abstraction patterns.

Production-ready and actively maintained. The project is at v4.5.0 (Spring Boot 3.3.2, Java 21), has published Docker images for amd64/arm64, includes comprehensive pre-built startup scripts in .package/script/, and maintains installation documentation. Regular commits and closed issue tracking indicate ongoing active development, though single-author maintenance is a concern.

Moderate risk due to single-maintainer pattern (zhaojun) visible in repo structure. Large dependency surface (AWS SDK BOM, multiple cloud SDKs, Jackson, MapStruct, Flyway, SQLite) increases supply chain exposure. No visible test directory in file structure suggests test coverage may be limited. Latest commit recency not shown but version jump (3.x → 4.5.0) indicates potential breaking changes between releases.

No specific PR or milestone data visible in provided files, but recent version bump to 4.5.0 with Spring Boot 3.3.2 upgrade and Java 21 targeting indicates active modernization. .github/ISSUE_TEMPLATE/ shows structured issue tracking. Documentation site (docs.zfile.vip) and demo (demo.zfile.vip) are maintained, suggesting ongoing feature additions and bug fixes.

git clone https://github.com/zfile-dev/zfile.git
cd zfile
mvn clean install
mvn spring-boot:run

Alternatively, one-liner installation: curl -sSL https://docs.zfile.vip/install.sh -o install.sh && chmod +x install.sh && ./install.sh

Daily commands:

mvn spring-boot:run

Or package and run: mvn clean package && java -jar target/zfile-4.5.0.jar. Docker: docker build -t zfile . && docker run -p 8080:8080 zfile. Default port is 8080 (inferred from Spring Boot standard).

Add a new Storage Source Type

1. Create a storage provider class implementing the storage API interface in src/main/java/im/zhaojun/zfile/module/storage/model (not shown in file list but follows Spring pattern) (src/main/java/im/zhaojun/zfile/core/config/spring/StringToEnumConverterFactory.java)
2. Register the converter factory to handle enum parsing of your new storage type (src/main/java/im/zhaojun/zfile/core/config/spring/WebMvcConfig.java)
3. Add storage credentials and configuration properties to the system (src/main/java/im/zhaojun/zfile/core/config/ZFileProperties.java)
4. Create an API controller endpoint to handle storage-specific operations (src/main/java/im/zhaojun/zfile/core/controller/FrontIndexController.java)

Add a new API Endpoint with Rate Limiting

1. Create a new REST controller method in src/main/java/im/zhaojun/zfile/module/system/controller (pattern location) (src/main/java/im/zhaojun/zfile/core/annotation/ApiLimit.java)
2. Decorate the method with @ApiLimit annotation to enable rate limiting (src/main/java/im/zhaojun/zfile/core/aspect/ApiLimitAspect.java)
3. Define custom error response using ErrorCode enum if rate limit exceeded (src/main/java/im/zhaojun/zfile/core/exception/ErrorCode.java)
4. Response will be automatically wrapped by CommonResultControllerAdvice (src/main/java/im/zhaojun/zfile/core/aspect/CommonResultControllerAdvice.java)

Implement a Cached Query

1. Inject ZFileCacheManager into your service class (src/main/java/im/zhaojun/zfile/core/cache/ZFileCacheManager.java)
2. Configure Spring Cache with @Cacheable annotation on your service methods (src/main/java/im/zhaojun/zfile/core/config/spring/SpringCacheConfig.java)
3. Customize Redis serialization using Jackson if needed (src/main/java/im/zhaojun/zfile/core/config/security/SaTokenDaoRedisJackson.java)
4. Cache TTL and eviction policy configured via ZFileProperties (src/main/java/im/zhaojun/zfile/core/config/ZFileProperties.java)

Add a Custom Exception Type

1. Create new exception class extending BizException in src/main/java/im/zhaojun/zfile/core/exception/biz/ (src/main/java/im/zhaojun/zfile/core/exception/core/BizException.java)
2. Register error code in ErrorCode enum with HTTP status and message (src/main/java/im/zhaojun/zfile/core/exception/ErrorCode.java)
3. GlobalExceptionHandler automatically maps exception to standardized response (src/main/java/im/zhaojun/z)

Java 21 requirement: pom.xml explicitly targets <java.version>21</java.version>; building with Java 17 will fail. Flyway migrations: flyway.version 10.12.0 is configured, so SQLite schemas must be versioned in src/main/resources/db/migration/; manual SQL edits outside Flyway can cause upgrade failures. Spring Boot 3.3.2 Jakarta EE breaking change: old javax.* imports will not work; ensure all imports use jakarta.*. SQLite limitations: SQLite JDBC 3.46.0.1 has concurrency bottlenecks under high-load file uploads; not suitable for large teams. Knife4j docs endpoint: API documentation likely exposed at /doc.html by default; may leak internal API structure in production without proper security filtering. MapStruct annotation processing: requires Maven compiler plugin configuration (verify maven-compiler-plugin in pom.xml includes annotationProcessorPaths).

• Storage Abstraction Layer / Provider Pattern — ZFile's core value is hiding implementation details of S3, OneDrive, FTP, etc. behind a unified interface. Understanding how different storage backends are abstracted (likely via interfaces/abstract classes) is essential to adding new storage types or debugging backend-specific bugs.
• Aspect-Oriented Programming (AOP) — ApiLimitAspect and DemoDisableAspect show cross-cutting concerns injected via @Aspect annotations. This pattern decouples rate-limiting and feature toggles from business logic; critical for understanding how global behaviors are applied to all endpoints.
• Multi-Tenancy / Dynamic DataSource Routing — DataSourceBeanPostProcessor suggests support for multiple storage sources per user or role. Understanding how connections are routed at runtime is vital for the multi-user feature mentioned in README (per-user storage assignments).
• Distributed Caching Strategy — ZFileCacheManager abstracts caching logic across multiple remote storage backends with different latencies. Cache invalidation bugs (stale files after upload) are high-risk; understanding TTL, key generation, and eviction is crucial.
• Spring Boot Auto-Configuration and Property Binding — ZFileProperties.java centralizes all config as typed beans via @ConfigurationProperties. This enables externalized config (application.yml) without code changes; essential for Docker/Kubernetes deployments.
• Direct Link / Token-Based Download Expiry — README mentions 'generate direct links' with optional expiration. This likely involves cryptographic tokens (JWT or session-based) with time-limited validity; understanding token lifecycle prevents security bugs like indefinite access or token reuse.
• Flyway Database Migration — Flyway 10.12.0 manages SQLite schema versioning across releases. Adding new features often requires schema changes; understanding how migrations are versioned (V1__*.sql, V2__*.sql) prevents conflicts and data loss.

• cloudreve/Cloudreve — Chinese-developed self-hosted cloud storage UI; similar multi-storage aggregation and file preview features, written in Go instead of Java
• nextcloud/server — Mature PHP-based self-hosted file sync platform; broader enterprise features but heavier than ZFile; shares storage-agnostic architecture goals
• minio/minio — S3-compatible object storage server; complementary backend that ZFile can connect to as a storage source
• cmlh/aspnetcore-cloud-drive — Multi-cloud aggregation in .NET; demonstrates similar architectural patterns for unified cloud storage interface in different ecosystem
• spring-projects/spring-cloud — Spring Cloud parent project for cloud-native patterns; ZFile could adopt service discovery and config server from Spring Cloud for horizontal scaling

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add comprehensive unit tests for core storage abstraction layer

The repo lacks visible test coverage for the storage abstraction implementations. With multiple storage types (OneDrive, local, S3, etc.) being managed, adding unit tests for src/main/java/im/zhaojun/zfile/core would significantly improve reliability. This is critical given the file browser/upload/download functionality where bugs could cause data loss.

• [ ] Create src/test/java/im/zhaojun/zfile/core directory structure mirroring main
• [ ] Add unit tests for storage adapter implementations (likely in src/main/java/im/zhaojun/zfile/core/storage or similar, not shown in file list)
• [ ] Test cache manager behavior in ZFileCacheManager.java with mock cache backends
• [ ] Add integration tests for SaTokenDaoRedisJackson.java security token serialization/deserialization
• [ ] Ensure >80% code coverage for core package and add coverage reporting to CI

Add GitHub Actions workflow for automated Docker image builds and releases

The repo contains a Dockerfile but no visible CI/CD pipeline for building and publishing Docker images. Given this is a deployable application with a .package/script directory for deployment, automating Docker builds on release tags would significantly improve distribution and reduce manual deployment burden.

• [ ] Create .github/workflows/docker-build.yml that triggers on version tags (v*..))
• [ ] Build Docker image using the existing Dockerfile, tag it with version and latest
• [ ] Push to a public registry (Docker Hub or GitHub Container Registry)
• [ ] Add image metadata labels (version, build date, maintainers)
• [ ] Document in README.md the available Docker images and usage instructions

Refactor datasource/MyBatis configuration and add database migration validation tests

The MyBatis configuration has multiple type handlers (CollectionIntegerTypeHandler, CollectionStrTypeHandler, CollectionTypeHandler) and custom components (MyDatabaseIdProvider, MyMetaObjectHandler, DataSourceBeanPostProcessor). These interdependent components lack visible tests. Combined with Flyway migrations (version 10.12.0 in pom.xml), this creates risk of migration failures in production.

• [ ] Create src/test/java/im/zhaojun/zfile/core/config/mybatis/ with tests for each custom TypeHandler
• [ ] Add integration test for DataSourceBeanPostProcessor.java to verify dynamic datasource configuration
• [ ] Create Flyway migration validation tests that verify all SQL migrations execute correctly against test databases (H2, SQLite)
• [ ] Test MyMetaObjectHandler.java with sample entities to ensure audit field population (likely created/updated timestamps)
• [ ] Document expected database schema in DEVELOPMENT.md or similar

• Add integration tests for storage backends: No src/test directory visible in file structure. Create unit tests for DataSourceBeanPostProcessor to verify dynamic datasource bean registration works correctly with different cloud provider configurations (S3, OneDrive, Google Drive).
• Implement rate limit metrics endpoint: ApiLimitAspect.java exists but no metrics export. Add a /metrics/api-limits endpoint that returns current rate limit state (requests remaining, reset time) using the @ApiLimit annotation metadata; useful for frontend to warn users before hitting limits.
• Document cache invalidation strategy: ZFileCacheManager.java lacks inline documentation on TTL, cache key structure, and invalidation triggers. Add JavaDoc explaining which operations (upload, delete, move) trigger cache eviction for each storage backend, since caching across multiple backends (S3, local, FTP) could cause stale data bugs.

• High · Outdated Jackson Dependencies — pom.xml - jackson-bom.version property. The pom.xml specifies jackson-bom.version as 2.14.1, which is significantly outdated. Current stable versions are 2.17.x+. This version contains multiple known CVEs including deserialization vulnerabilities that could lead to remote code execution. Fix: Update jackson-bom to version 2.17.0 or later. Review all Jackson-related dependencies for compatibility.
• High · Outdated SnakeYAML Library — pom.xml - snakeyaml.version property. snakeyaml.version is set to 2.0, which is outdated. Current stable versions are 2.2+. SnakeYAML 2.0 contains CVE-2023-35851 related to denial of service vulnerabilities in YAML parsing. Fix: Update snakeyaml to version 2.2 or later to patch known YAML parsing vulnerabilities.
• Medium · Deprecated Spring Boot Version — pom.xml - spring-boot-starter-parent version. Spring Boot 3.3.2 is being used, but version 3.4.x or 3.5.x are available with security patches and improvements. While 3.3.2 may still receive patches, using a more recent version ensures faster security updates. Fix: Upgrade to Spring Boot 3.4.x or later to ensure timely security patches.
• Medium · Incomplete POM.xml File — pom.xml - dependencies section. The provided pom.xml appears to be truncated mid-dependency declaration (GraalVM SDK dependency is incomplete). This makes it impossible to fully analyze all dependencies for vulnerabilities. The incomplete state suggests the file may not be properly validated. Fix: Provide complete pom.xml file and validate XML structure. Run 'mvn dependency-check' to scan all dependencies for known vulnerabilities.
• Medium · Potential Path Traversal Vulnerability — src/main/java/im/zhaojun/zfile/core/exception/biz/FilePathSecurityBizException.java and related controllers. The file structure indicates presence of 'FilePathSecurityBizException' suggesting path traversal protection attempts. However, without analyzing the actual controller and service code, file access patterns cannot be verified. The file browsing system is at high risk for path traversal attacks if not properly validated. Fix: Implement strict path canonicalization and validation. Use whitelist-based path validation. Never construct file paths from user input directly. Review all file access in FrontIndexController and storage modules.
• Medium · Missing CORS and Security Headers Configuration — src/main/java/im/zhaojun/zfile/core/config/spring/WebMvcConfig.java. While WebMvcConfig.java is present, without viewing its contents, proper CORS restrictions and security headers (CSP, X-Frame-Options, etc.) cannot be verified. The presence of file sharing/streaming features suggests CORS may be permissive. Fix: Configure restrictive CORS policies. Implement security headers: Content-Security-Policy, X-Frame-Options: DENY, X-Content-Type-Options: nosniff, Strict-Transport-Security.
• Medium · SQLi Risk in MyBatis Configuration — src/main/java/im/zhaojun/zfile/core/config/mybatis/. Custom TypeHandlers and MyBatis configuration are present (CollectionTypeHandler, MyDatabaseIdProvider). Dynamic SQL construction through these handlers could be vulnerable if not properly parameterized. Fix: Audit all MyBatis XML mappings to ensure parameterized queries are used. Never construct SQL strings from user input. Use MyBatis parameterization exclusively.
• Medium · Sensitive Data in Docker Image — Dockerfile. The Dockerfile uses multi-stage build which is good practice, but the final image runs as root user (implicit). No explicit USER directive limits privileges, and no runtime security constraints (read-only filesystem, etc.) are configured. Fix: Add 'USER app-user' after installing dependencies. Use '--read-only' flag when running container. Add health checks. Consider

LLM-derived; treat as a starting point, not a security audit.
