src/main/java/com/iemr/ecd/utils/mapper/CookieUtil.java (2)
12-13: Add class-level documentation.Consider adding Javadoc documentation to describe the class's purpose, responsibilities, and usage in the JWT authentication flow.
@Service +/** + * Utility class for managing JWT tokens in cookies. + * Provides methods for setting, retrieving, and managing secure HTTP-only cookies + * used in the JWT authentication flow. + */ public class CookieUtil {
15-25: Consider streamlining implementation and adding documentation.The implementation is correct but could benefit from the following improvements:
- Use Java streams for more concise implementation
- Add parameter validation
- Add method documentation
+ /** + * Retrieves the value of a specific cookie from the HTTP request. + * @param request The HTTP request containing the cookies + * @param cookieName The name of the cookie to retrieve + * @return Optional containing the cookie value if found, empty otherwise + * @throws IllegalArgumentException if cookieName is null or empty + */ public Optional<String> getCookieValue(HttpServletRequest request, String cookieName) { + if (cookieName == null || cookieName.trim().isEmpty()) { + throw new IllegalArgumentException("Cookie name cannot be null or empty"); + } + Cookie[] cookies = request.getCookies(); - if (cookies != null) { - for (Cookie cookie : cookies) { - if (cookieName.equals(cookie.getName())) { - return Optional.of(cookie.getValue()); - } - } - } - return Optional.empty(); + return cookies == null ? Optional.empty() : + Arrays.stream(cookies) + .filter(cookie -> cookieName.equals(cookie.getName())) + .map(Cookie::getValue) + .findFirst(); }src/main/java/com/iemr/ecd/utils/mapper/JwtAuthenticationUtil.java (4)
28-28: Declare Logger as a static final fieldIt's a common practice to declare the
Loggeras aprivate static finalfield to ensure there's only one instance per class and to improve performance.Apply this diff:
- private final Logger logger = LoggerFactory.getLogger(this.getClass().getName()); + private static final Logger logger = LoggerFactory.getLogger(JwtAuthenticationUtil.class);
36-60: Decouple utility class from HTTP-specific response handlingThe method
validateJwtTokenreturnsResponseEntity<String>, coupling the utility class with HTTP-specific classes. Consider refactoring the method to throw exceptions upon validation failure and return the username directly. This keeps the utility class focused on JWT validation logic and allows controllers to handle HTTP responses appropriately.Refactor the method as follows:
- public ResponseEntity<String> validateJwtToken(HttpServletRequest request) { + public String validateJwtToken(HttpServletRequest request) throws ECDException { Optional<String> jwtTokenOpt = cookieUtil.getCookieValue(request, "Jwttoken"); if (jwtTokenOpt.isEmpty()) { - return ResponseEntity.status(HttpStatus.UNAUTHORIZED) - .body("Error 401: Unauthorized - JWT Token is not set!"); + throw new ECDException("JWT Token is not set!"); } String jwtToken = jwtTokenOpt.get(); // Validate the token Claims claims = jwtUtil.validateToken(jwtToken); if (claims == null) { - return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Error 401: Unauthorized - Invalid JWT Token!"); + throw new ECDException("Invalid JWT Token!"); } // Extract username from token String usernameFromToken = claims.getSubject(); if (usernameFromToken == null || usernameFromToken.isEmpty()) { - return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body("Error 401: Unauthorized - Username is missing!"); + throw new ECDException("Username is missing in JWT Token!"); } // Return the username if valid - return ResponseEntity.ok(usernameFromToken); + return usernameFromToken; }This change will make the method cleaner and delegates HTTP response handling to the controller layer.
75-77: Handle the possibility ofgetUserByUserIDreturningOptional<Users>To prevent
NullPointerException, consider changing thegetUserByUserIDmethod to return anOptional<Users>and handle the case where the user is not found.Apply this diff:
- Users user = userLoginRepo.getUserByUserID(userIdLong); - if (user == null) { + Optional<Users> userOpt = userLoginRepo.getUserByUserID(userIdLong); + if (userOpt.isEmpty()) { throw new ECDException("Invalid User ID."); } + Users user = userOpt.get();Ensure that the
UserLoginRepointerface is updated accordingly.
87-87: Use SLF4J placeholders instead of string concatenation in loggerAvoid string concatenation in log statements. Using placeholders is more efficient and aligns with best practices.
Apply this diff:
- logger.error("Validation failed: " + e.getMessage(), e); + logger.error("Validation failed: {}", e.getMessage(), e);src/main/java/com/iemr/ecd/repository/ecd/UserLoginRepo.java (1)
14-15: Simplify repository method by using derived query methodsYou can leverage Spring Data JPA's method naming conventions to simplify your code and avoid using explicit
@Queryannotations. Replace the custom query method with a derived query method.Apply this change:
- @Query(" SELECT u FROM Users u WHERE u.userID = :userID AND u.deleted = false ") - public Users getUserByUserID(@Param("userID") Long userID); + public Users findByUserIDAndDeletedFalse(Long userID);src/main/environment/ecd_ci.properties (1)
18-18: Ensure JWT secret key is securely managedIncluding secret keys directly in properties files can pose a security risk, especially if the file is checked into source control. Consider using environment variables or a secure secrets management system to manage the
jwt.secret.src/main/java/com/iemr/ecd/utils/mapper/FilterConfig.java (1)
8-19: Avoid double registration of filters; use either@ComponentorFilterRegistrationBeanSince
JwtUserIdValidationFilteris annotated with@Component, it will be automatically detected and registered by Spring Boot. Registering it again usingFilterRegistrationBeanmay lead to the filter being registered twice. Consider removing either the@Componentannotation fromJwtUserIdValidationFilteror the explicit registration inFilterConfig.To fix this, you can remove the
@Componentannotation fromJwtUserIdValidationFilterand keep the explicit registration:-@Component public class JwtUserIdValidationFilter implements Filter {Or remove the
FilterConfigclass if explicit registration is not needed.src/main/environment/ecd_test.properties (1)
18-18: Ensure JWT secret key is securely managedIncluding secret keys directly in properties files can pose a security risk, especially if the file is checked into source control. Consider using environment variables or a secure secrets management system to manage the
jwt.secret.src/main/java/com/iemr/ecd/dao/Users.java (2)
89-97: Enhance audit fieldsThe audit fields (createdDate, lastModDate) should be automatically managed.
Add JPA auditing:
- @Expose - @Column(name = "CreatedDate") - private Timestamp createdDate; + @CreatedDate + @Column(name = "CreatedDate", updatable = false) + private Timestamp createdDate; - @Expose - @Column(name = "LastModDate") - private Timestamp lastModDate; + @LastModifiedDate + @Column(name = "LastModDate") + private Timestamp lastModDate;
1-99: Consider implementing additional security measuresFor a JWT-based authentication system, consider these security enhancements:
- Add fields for tracking:
- Last password change
- Failed login attempts
- Account lockout status
- Password reset tokens
- Implement password complexity requirements
- Add multi-factor authentication support
src/main/java/com/iemr/ecd/utils/mapper/JwtUtil.java (1)
21-21: Consider making token expiration time configurableThe expiration time is hardcoded which reduces flexibility across different environments.
Consider making it configurable via properties:
-private static final long EXPIRATION_TIME = 24 * 60 * 60 * 1000; // 1 day in milliseconds +@Value("${jwt.expiration.time:86400000}") // Default to 24 hours +private long expirationTime;pom.xml (1)
235-254: Update JWT dependencies to latest stable versionThe current JWT dependencies are using version 0.11.5, while newer versions are available with security improvements.
Consider updating to the latest stable version:
<dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt-api</artifactId> - <version>0.11.5</version> + <version>0.12.3</version> </dependency> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt-impl</artifactId> - <version>0.11.5</version> + <version>0.12.3</version> <scope>runtime</scope> </dependency> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt-jackson</artifactId> - <version>0.11.5</version> + <version>0.12.3</version> <scope>runtime</scope> </dependency>

💡 Codebase verification
Add test coverage and enhance security measures
Based on the codebase analysis:
- No dedicated tests exist for
CookieUtil- only a general application test file is present CookieUtilis properly integrated withJwtAuthenticationUtilfor token extraction- Current implementation lacks comprehensive error handling and security validations
Required actions:
- Create
src/test/java/com/iemr/ecd/utils/mapper/CookieUtilTest.javawith test cases for:- Token extraction from cookies
- Null/empty cookie scenarios
- Cookie security attributes validation
- Add input validation in
getJwtTokenFromCookieto handle null cookies (similar togetCookieValue) - Consider adding CSRF protection mechanisms
🔗 Analysis chain
Verify integration with JWT components and add comprehensive tests.
As this is a security-critical component handling JWT tokens, please ensure:
- Integration testing with
JwtAuthenticationUtilandJwtUserIdValidationFilter - Unit tests covering all edge cases (null cookies, missing tokens, etc.)
- Security testing for cookie attributes and token handling
Let me check the actual integration and test coverage by examining the related files.
Let me check for test files in the standard test directory structure and examine the JWT filter implementation.

Implement measures against token replay attacks
The current implementation lacks protection against token replay attacks.
Add a nonce claim and maintain a blacklist of used tokens:
public String generateToken(String username, String userId) {
Date now = new Date();
Date expiryDate = new Date(now.getTime() + EXPIRATION_TIME);
+ String nonce = java.util.UUID.randomUUID().toString();
return Jwts.builder()
.setSubject(username)
.claim("userId", userId)
+ .claim("nonce", nonce)
.setIssuedAt(now)
.setExpiration(expiryDate)
.signWith(getSigningKey(), SignatureAlgorithm.HS256)
.compact();
}Also, implement a token blacklist service to track used tokens until their expiration.

💡 Codebase verification
Add unit tests for CookieUtil to ensure secure JWT token handling
The verification confirms that:
- No dedicated test class exists for CookieUtil
- CookieUtil is a critical component in JWT authentication flow
- It's actively used in JwtAuthenticationUtil for token extraction and validation
Required test cases:
getCookieValue():- Null cookies array
- Empty cookies array
- Cookie with matching name
- Cookie not found
addJwtTokenToCookie():- Verify security attributes (HttpOnly, Secure flags)
- Correct path and expiration settings
getJwtTokenFromCookie():- Successful token extraction
- Null handling
- Empty cookie array handling
Create tests under src/test/java/com/iemr/ecd/utils/mapper/CookieUtilTest.java
🔗 Analysis chain
Add comprehensive test coverage for this security-critical component.
As this class handles JWT tokens, it requires thorough testing:
Please add tests covering:
- Null/empty inputs
- Missing cookies
- Security attributes validation
- Token extraction scenarios
- Integration with JWT authentication flow
Would you like me to help create a comprehensive test suite for this class?
Let me check the JWT authentication flow integration to better understand the test coverage requirements.
Let me check the actual usage of CookieUtil in the authentication flow to provide more specific test requirements.

Potential bean conflict with EcdApiApplication RedisTemplate
There are two RedisTemplate bean definitions:
RedisTemplate<String, Users>hereRedisTemplate<String, Object>in EcdApiApplication
This could lead to autowiring conflicts and unexpected behavior.

- Consolidating these beans into a single configuration class
- Using distinct bean names if both are needed:

Redis security configuration needs enhancement
The Redis configuration is currently using default settings with no security measures:
- Redis is configured to run on localhost:6379 without password protection
- No SSL/TLS configuration is present
- No connection timeout settings are defined
This setup is insufficient for a production environment, especially when handling JWT session data. Consider adding the following properties to application.properties:
spring.redis.passwordspring.redis.ssl=truespring.redis.timeoutspring.redis.connect-timeout
🔗 Analysis chain
Verify Redis security configuration
The Redis configuration lacks security settings. When implementing JWT authentication, it's crucial to secure the Redis instance that might store sensitive session data.
Consider adding:
- Redis password configuration
- SSL/TLS settings
- Connection timeout settings

🛠️ Refactor suggestion
Move Redis configuration to RedisConfig class
Redis configuration should be centralized in the RedisConfig class rather than split across multiple files. This violates the Single Responsibility Principle.
- Remove this RedisTemplate bean
- Update the one in RedisConfig to handle both Users and Object types if needed
- Use proper qualifiers for different template instances

💡 Codebase verification
Based on the findings, I can now provide the final response:
Security configuration requires attention
Several security concerns need to be addressed:
- JWT expiration is hardcoded to 24 hours in JwtUtil.java. Consider making it configurable through properties
- JWT secret is empty in dev/test/uat properties files (
jwt.secret=) - Cookie security attributes (httpOnly, secure, sameSite) are not visible in the implementation
- Redis cache expiration policy is not configured, which could lead to stale user sessions
🔗 Analysis chain
Verify JWT security configuration
Please ensure the following security considerations are addressed:
- JWT token expiration is properly configured
- Secure cookie settings are enforced
- Redis cache expiration aligns with JWT expiration
Run the following script to verify JWT and cookie configurations:
Let me try a different approach to gather the necessary information.
Let me check the properties files for JWT and cookie configurations.
Let me try one final search to locate the CookieUtil and JwtUtil implementations.
