Summary of Changes
Hello @wlgns12370, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly refactors the token verification process within the application's security configuration. It introduces a dedicated Whitelist mechanism to explicitly define which API endpoints and HTTP methods can bypass token authentication, thereby improving the clarity, maintainability, and flexibility of the security filter chain.
Highlights
- Refactored Token Filter: The
AccessTokenFilterhas been renamed toTokenFilterand its internal logic for skipping URLs has been removed and externalized. This change streamlines the filter's primary responsibility to token processing, delegating URL whitelisting to a dedicated component. - Introduced Whitelist Mechanism: A new
Whitelistenum has been implemented to centralize and manage API endpoints and HTTP methods that are exempt from token validation. This provides a clear and configurable way to define paths that do not require authentication. - Method-Specific Token Validation: The new
Whitelistallows for more granular control over token requirements by enabling whitelisting based on both the URI path and the HTTP method. This means certain paths might be accessible without a token only for specific HTTP verbs (e.g., GET requests). - Security Configuration Update: The
SecurityConfigclass has been updated to integrate the newTokenFilterand leverage theWhitelistfor determining which requests bypass token authentication, ensuring the security chain correctly applies the new rules.

Code Review
This pull request refactors the token validation logic by introducing a Whitelist enum to manage authentication-exempt endpoints, which improves maintainability. The AccessTokenFilter is also renamed to TokenFilter to better reflect its broader responsibilities. The review focuses on improving performance, maintainability, and error handling.

| return Arrays.stream(values()) |

The values() method on an enum creates a new array each time it's called. Since this check is in a filter that runs for every request, this can create unnecessary object allocations and affect performance. Caching the result of values() in a static final field can optimize this.

🔇 Additional comments (10)
src/main/java/life/mosu/mosuserver/global/filter/WhitelistMethod.java (1)
3-13: LGTM! Clean enum implementation.The enum properly defines all standard HTTP methods plus the useful
ALLconstant for flexible whitelist configuration. The implementation follows Java conventions and serves its purpose effectively.src/main/java/life/mosu/mosuserver/global/config/SecurityConfig.java (3)
7-14: LGTM! Import organization improved.The import statements are better organized and the TokenFilter import correctly reflects the class rename from AccessTokenFilter.
68-68: LGTM! Field rename maintains consistency.The field rename from
accessTokenFiltertotokenFilterproperly aligns with the class rename and maintains naming consistency.
146-147: LGTM! Filter chain properly updated.The filter chain configuration correctly uses the renamed
tokenFilterfield and maintains the proper filter ordering.src/main/java/life/mosu/mosuserver/global/filter/TokenFilter.java (4)
28-28: LGTM! Class rename reflects broader functionality.The rename from
AccessTokenFiltertoTokenFilterbetter represents the filter's expanded role in handling multiple token types (access, signup, password tokens).
45-49: LGTM! Excellent whitelist integration.The replacement of hardcoded URL skip logic with
Whitelist.isWhitelisted(request)is a significant architectural improvement that:
- Centralizes whitelist management
- Makes the code more maintainable
- Provides method-based filtering capabilities
The enhanced logging that includes both URI and HTTP method improves debugging visibility.
51-51: LGTM! Code optimization and formatting improvement.Moving the
requestUriextraction outside the conditional blocks eliminates duplication and improves code efficiency.
53-103: LGTM! Core token validation logic properly preserved.The essential token validation logic for different token types (reissue, signup, password, access tokens) remains unchanged, ensuring backward compatibility while benefiting from the new whitelist functionality.
src/main/java/life/mosu/mosuserver/global/filter/Whitelist.java (2)
10-13: LGTM! Well-structured enum with appropriate annotations.The Lombok annotations are correctly used -
@RequiredArgsConstructorworks well for enum constructors, and@Getterprovides clean access to the fields.
46-59: LGTM! Efficient whitelist matching implementation.The implementation correctly handles:
- Prefix-based path matching using
startsWith()- Method-specific and wildcard (
ALL) matching- Clean use of streams and Optional
The logic flow from
isWhitelisted()tofindMatch()is clear and efficient.

🛠️ Refactor suggestion
Review whitelist entries for security considerations.
The whitelist structure is well-organized, but consider these security aspects:
-
Line 18:
ACTUATORwithALLmethods could expose sensitive endpoints. Consider restricting toGETonly or implementing additional security. -
Lines 26-29: Static resources (CSS, JS, FONTS, IMAGES) typically only need
GETmethod access, notALLmethods. -
Line 36:
MASTERendpoint is marked for deletion but still active withALLmethods - ensure this is removed when appropriate.
The GET-only restrictions for EVENT, FAQ, and NOTICE endpoints are appropriate for read-only resources.
Consider this diff for static resources:
- CSS("/api/v1/css", WhitelistMethod.ALL),
- JS("/api/v1/js", WhitelistMethod.ALL),
- FONTS("/api/v1/fonts", WhitelistMethod.ALL),
- IMAGES("/api/v1/images", WhitelistMethod.ALL),
+ CSS("/api/v1/css", WhitelistMethod.GET),
+ JS("/api/v1/js", WhitelistMethod.GET),
+ FONTS("/api/v1/fonts", WhitelistMethod.GET),
+ IMAGES("/api/v1/images", WhitelistMethod.GET),📝 Committable suggestion

In src/main/java/life/mosu/mosuserver/global/filter/Whitelist.java between lines
16 and 41, update the whitelist entries for better security by changing the
ACTUATOR endpoint's allowed methods from ALL to GET only to prevent exposure of
sensitive operations, restrict the static resource endpoints CSS, JS, FONTS, and
IMAGES to GET methods instead of ALL, and ensure the MASTER endpoint marked for
deletion is removed entirely when no longer needed to avoid unintended access.
