13-13: LGTM! Consider adding a Javadoc comment.The new
deleteTokenmethod is well-aligned with the PR objectives for implementing the logout feature. The method signature is consistent with Java conventions and other methods in the interface.To improve documentation, consider adding a Javadoc comment for the new method. Here's a suggested implementation:
/** * Deletes the token associated with the given name. * * @param name the name of the token to be deleted */ void deleteToken(final String name);
Line range hint
1-13: Consider adding a token refresh method and clarify cookie management responsibility.The
TokenServiceinterface provides a good set of basic operations for token management. However, there are two points to consider:
Token Refresh: Given that both refresh and access tokens are handled in the
saveOrUpdatemethod, it might be beneficial to add a dedicated method for refreshing tokens. This is a common operation in token-based authentication systems.Cookie Management: The PR objectives mention deleting tokens and related cookies upon logout. However, there's no explicit mention of cookie management in this interface. It would be helpful to clarify whether cookie management is the responsibility of this service or if it's handled elsewhere.
Here's a suggestion for adding a refresh method:
/** * Refreshes the access token using the provided refresh token. * * @param refreshToken the refresh token * @return the new access token */ String refreshToken(final String refreshToken);Regarding cookie management, if it's meant to be handled by this service, consider adding methods for it. If not, it might be worth documenting where that responsibility lies.
src/main/java/taco/klkl/domain/token/dao/TokenRepository.java (1)
16-17: LGTM! Consider adding documentation and additional methods.The
deleteByNamemethod is a good addition that aligns well with the PR objective of implementing logout functionality. It follows Spring Data JPA naming conventions and is consistent with the existingfindByNamemethod.To further improve the interface, consider the following suggestions:
- Add Javadoc to document the method's purpose and parameters.
- For consistency, you might want to add a
deleteByAccessTokenmethod as well.- If useful for your use case, consider adding a method that returns a boolean indicating whether a deletion occurred (e.g.,
boolean deleteByName(final String name)).src/main/java/taco/klkl/global/config/security/CustomLogoutHandler.java (1)
18-27: LGTM with suggestions: Logout method implementation is correct but could be enhanced.The
logoutmethod correctly overrides theLogoutHandlerinterface and implements the token deletion logic. Good use of null checking and pattern matching forinstanceof.Suggestions for improvement:
- Consider logging when the authentication is null or not an instance of
UserDetails.- You might want to use the
requestorresponseobjects, e.g., for clearing cookies or adding headers.Here's a potential enhancement:
@Override public void logout( HttpServletRequest request, HttpServletResponse response, Authentication authentication ) { if (authentication != null && authentication.getPrincipal() instanceof UserDetails userDetails) { tokenService.deleteToken(userDetails.getUsername()); + // Clear any relevant cookies + // For example: response.addCookie(new Cookie("auth_cookie", null)); + } else { + // Log the unexpected scenario + // logger.warn("Logout attempted with invalid authentication"); } }src/main/java/taco/klkl/global/config/security/CustomLogoutSuccessHandler.java (2)
14-16: LGTM: Class declaration and annotations are appropriate.The class name and annotations are well-chosen. Implementing
LogoutSuccessHandleris correct for customizing logout behavior.Consider adding a brief Javadoc comment to describe the purpose of this class, which can be helpful for future maintainers. For example:
/** * Custom implementation of LogoutSuccessHandler to manage the logout process. * This handler clears the access token cookie and sets the appropriate response status. */ @Component @RequiredArgsConstructor public class CustomLogoutSuccessHandler implements LogoutSuccessHandler { // ... rest of the class }
1-30: Summary: Implementation successfully addresses the logout feature (KL-183).The
CustomLogoutSuccessHandlerclass effectively implements the logout functionality as described in the PR objectives. It handles token authentication by clearing the access token cookie upon logout, which aligns with the requirement to delete tokens and related cookies.Key points:
- The class is well-structured and follows Spring best practices.
- The logout process is correctly implemented, clearing the access token and setting the appropriate response status.
- The implementation is concise and focused on the core logout functionality.
While the implementation is solid, consider the suggestions in the previous comments for minor improvements in documentation and error handling.
To further enhance the logout process, consider implementing these additional security measures:
- Invalidate the user's session on the server-side if you're using server-side sessions.
- If you're using refresh tokens, ensure they are also invalidated during the logout process.
- Consider implementing CSRF protection for the logout endpoint if not already in place.
These measures will provide a more robust and secure logout mechanism.
src/main/java/taco/klkl/global/util/TokenUtil.java (3)
17-24: LGTM: Well-implemented token resolution method.The
resolveTokenmethod is efficiently implemented using Java 8+ features. It safely handles null cookies and correctly retrieves the access token.Suggestions for minor improvements:
- Consider adding a comment explaining the significance of a null return value.
- Adding debug logging could be beneficial for troubleshooting.
Example:
public String resolveToken(HttpServletRequest request) { String token = Optional.ofNullable(request.getCookies()) .flatMap(cookies -> Arrays.stream(cookies) .filter(cookie -> ACCESS_TOKEN.equals(cookie.getName())) .findFirst() .map(Cookie::getValue)) .orElse(null); // Log for debugging (consider using a logging framework) System.out.println("Resolved token: " + (token != null ? "found" : "not found")); return token; // Returns null if the access token cookie is not present }
36-42: LGTM with suggestions: Access token cookie clearing method.The
clearAccessTokenCookiemethod effectively clears the access token cookie. However, there are a few security enhancements that could be made:
- Set the Secure flag to true to ensure the cookie is only transmitted over HTTPS.
- Add the SameSite attribute, as it's present in the
addAccessTokenCookiemethod.- Consider adding debug logging for troubleshooting.
Here's an improved version:
public void clearAccessTokenCookie(HttpServletResponse response) { Cookie cookie = new Cookie(ACCESS_TOKEN, null); cookie.setPath("/"); cookie.setHttpOnly(true); cookie.setSecure(true); // Ensure cookie is only sent over HTTPS cookie.setMaxAge(0); cookie.setAttribute("SameSite", "Strict"); // Add SameSite attribute response.addCookie(cookie); // Log for debugging (consider using a logging framework) System.out.println("Access token cookie cleared"); }These changes will enhance the security of the cookie clearing process and maintain consistency with the
addAccessTokenCookiemethod.

1-43: Good overall structure with room for documentation improvement.The
TokenUtilclass is well-structured and follows the Single Responsibility Principle by focusing on token-related operations. The new methods complement the existingaddAccessTokenCookiemethod, providing a comprehensive set of token utilities.Suggestions for improvement:
- Add class-level JavaDoc to explain the purpose and usage of the
TokenUtilclass.- Ensure consistent error handling across all methods (e.g., logging or throwing exceptions).
Example of class-level JavaDoc:
/** * Utility class for handling access token operations via cookies. * This class provides methods to add, resolve, and clear access token cookies. * It is designed to work with HTTP requests and responses in a web application context. */ @Component public class TokenUtil { // ... existing methods ... }Consider implementing consistent error handling and logging across all methods to improve maintainability and debugging capabilities.

Line range hint
1-50: Consider adding logging statements for critical operations.The overall structure of the class is well-organized and follows Spring best practices. However, to improve observability and debugging, consider adding logging statements for critical operations such as token updates and deletions.
Here's an example of how you might add logging:
@Override @Transactional public Token updateToken(final String accessToken, final Token token) { if (token == null) { throw new IllegalArgumentException("Token cannot be null"); } token.update(token.getRefreshToken(), accessToken); + log.info("Token updated for name: {}", token.getName()); return token; } @Override @Transactional public boolean deleteToken(final String name) { if (tokenRepository.existsByName(name)) { tokenRepository.deleteByName(name); + log.info("Token deleted for name: {}", name); return true; } + log.warn("Attempt to delete non-existent token with name: {}", name); return false; }These logging statements will provide valuable information for monitoring and troubleshooting the application.

src/main/java/taco/klkl/global/config/security/CustomLogoutHandler.java (4)
3-10: LGTM: Imports are appropriate and concise.The imports cover all necessary classes for implementing a custom logout handler, including Jakarta Servlet, Spring Security, Lombok, and the custom
TokenService. No unused imports are present.
12-14: LGTM: Class declaration and annotations are well-structured.The
CustomLogoutHandlerclass is properly annotated with@Componentfor Spring bean management and@RequiredArgsConstructorfor dependency injection. Implementing theLogoutHandlerinterface is correct for providing custom logout functionality.
16-16: LGTM: Dependency declaration is correct.The
TokenServicedependency is properly declared asprivate final, which, combined with@RequiredArgsConstructor, ensures proper dependency injection and immutability.
1-28: Overall, the CustomLogoutHandler implementation is well-designed and aligns with the PR objectives.The class correctly implements the
LogoutHandlerinterface, providing a custom logout functionality that deletes the user's token upon logout. The code is well-structured, follows Spring best practices, and uses modern Java features.A few minor enhancements could be considered:
- Adding logging for edge cases.
- Utilizing the
requestandresponseobjects for additional logout-related actions if needed.These suggestions are optional and don't impact the core functionality of the logout process.
src/main/java/taco/klkl/global/config/security/CustomLogoutSuccessHandler.java (3)
1-13: LGTM: Package declaration and imports are appropriate.The package structure and imports are well-organized and relevant to the class's purpose. The use of Jakarta EE (Jakarta Servlet) indicates this is a modern Java EE application.
18-18: LGTM: Field declaration looks good.The use of a final field with constructor injection (via
@RequiredArgsConstructor) is a good practice for dependency management.Let's verify the
TokenUtilclass to ensure it has the necessary methods:
20-29: LGTM: Method implementation looks good, with some suggestions.The
onLogoutSuccessmethod correctly implements the logout process by clearing the access token and setting the appropriate response status.Consider the following suggestions:
- Add a log statement to record successful logouts, which can be useful for auditing and debugging.
- Consider wrapping the
response.getWriter().flush()in a try-catch block to handle potentialIOException.The
requestandauthenticationparameters are unused. Let's verify if this is intentional or if there are any security implications:If no results are found, it's likely that not using these parameters is standard in your application's security setup. However, if other implementations are found that use these parameters, consider whether similar logic should be applied here.
src/main/java/taco/klkl/global/util/TokenUtil.java (1)
5-13: LGTM: Import statements are correctly updated.The new import statements for
HttpServletRequest,Arrays, andOptionalare appropriately added to support the new methods in the class.src/main/java/taco/klkl/global/config/security/SecurityEndpoint.java (1)
44-44: LGTM! Verify logout flow for edge cases.The addition of the "/v1/logout/**" matcher to the USER_ROLE is consistent with the existing security configuration and ensures that only authenticated users can access the logout endpoint. This is a good security practice.
To ensure the logout functionality works as expected, please verify the following:
- An authenticated user can successfully log out.
- A logged-out user cannot access the logout endpoint again.
- The behavior is consistent across different browsers and devices.
Consider adding appropriate error handling for cases where an unauthenticated user attempts to access the logout endpoint.

48-58: Improved token resolution processThe replacement of the
resolveTokenmethod withtokenUtil.resolveToken(request)is a positive change. It simplifies the code and improves separation of concerns by delegating token resolution to a dedicated utility class. This modification enhances code organization without altering the overall behavior of the method.
71-74: Improved method signature withfinalmodifierThe addition of the
finalmodifier to theaccessTokenparameter in thesetAuthenticationmethod is a good practice. It clearly indicates that theaccessTokenshould not be modified within the method, improving code readability and helping to prevent accidental modifications. This change enhances code quality without affecting the method's functionality.src/main/java/taco/klkl/global/config/security/SecurityConfig.java (4)
41-42: Fields added for custom logout handlers are correctly declaredThe
customLogoutHandlerandcustomLogoutSuccessHandlerfields are properly added asfinaland will be injected via constructor injection thanks to the@RequiredArgsConstructorannotation.
76-77: Session management is correctly configured as statelessSetting the session management policy to
SessionCreationPolicy.STATELESSis appropriate for applications that use token-based authentication like JWT, ensuring that the server does not maintain session state.
101-107: Logout configuration is properly implementedThe logout functionality is correctly configured with the custom logout handler and success handler. Setting the
logoutUrlto/v1/logoutand permitting all users to access it is standard practice to allow users to log out without additional authentication.
101-107: Verify that the custom handlers are properly defined and registeredEnsure that
CustomLogoutHandlerandCustomLogoutSuccessHandlerare properly implemented as beans and manage the necessary logout logic, such as invalidating tokens and clearing cookies.Run the following script to confirm that the custom handlers are defined in the codebase:
