src/main/java/com/iemr/mmu/utils/http/AuthorizationHeaderRequestWrapper.java (2)
11-11: Follow Java naming conventions for instance variables.The instance variable should use camelCase naming convention rather than PascalCase.
-private final String Authorization; +private final String authorization;Remember to update references to this variable in the rest of the class.
18-24: Consider extracting the header name as a constant.The string "Authorization" is used multiple times in the class. Extracting it as a constant would improve maintainability.
+private static final String AUTHORIZATION_HEADER = "Authorization"; @Override public String getHeader(String name) { - if ("Authorization".equalsIgnoreCase(name)) { - return Authorization; + if (AUTHORIZATION_HEADER.equalsIgnoreCase(name)) { + return authorization; } return super.getHeader(name); }src/main/java/com/iemr/mmu/utils/RestTemplateUtil.java (1)
14-40: Add logging to track request entity creation.Adding logging would help with debugging and monitoring of the request entity creation process.
+import org.slf4j.Logger; +import org.slf4j.LoggerFactory; public class RestTemplateUtil { + private static final Logger logger = LoggerFactory.getLogger(RestTemplateUtil.class); + public static HttpEntity<Object> createRequestEntity(Object body, String authorization) { + logger.debug("Creating request entity with authorization: {}", authorization != null); ServletRequestAttributes servletRequestAttributes = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()); if (servletRequestAttributes == null) { + logger.debug("No servlet request attributes available, creating basic headers"); MultiValueMap<String, String> headers = new LinkedMultiValueMap<>(); headers.add(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE + ";charset=utf-8"); headers.add(HttpHeaders.AUTHORIZATION, authorization); return new HttpEntity<>(body, headers); } + logger.debug("Servlet request attributes available, creating complete headers"); HttpServletRequest requestHeader = servletRequestAttributes.getRequest(); // rest of the method... } }

26-32: Good enhancement to JWT token extraction.Making
getJwtTokenFromCookiestatic with null-safety checking improves code robustness by preventing NullPointerExceptions when no cookies are present. This change properly supports the centralized JWT token handling across the application.src/main/java/com/iemr/mmu/utils/http/HttpInterceptor.java (1)
63-66: Good addition of early return for missing Authorization headers.This early check allows requests without an Authorization header to bypass further validation, which helps optimize request processing. The addition of the log message also aids in debugging and monitoring unauthorized requests.

271-271: Consistent usage of the RestTemplateUtil for flag updates.The HTTP entity creation in updateProcessedFlagToCentral method is properly refactored to use the central utility method, maintaining consistency with the rest of the application.
src/main/java/com/iemr/mmu/utils/UserAgentContext.java (1)
1-18: Well-designed ThreadLocal implementation for User-Agent context.This is a good implementation of a thread-local context for storing User-Agent values, following Java best practices. The ThreadLocal approach ensures thread safety while making the User-Agent available throughout request processing without parameter passing.
The class properly provides methods to set, get, and clear the thread-local storage, which is essential for preventing memory leaks in thread-pooled environments.
src/main/java/com/iemr/mmu/utils/JwtUserIdValidationFilter.java (4)
9-10: Import added for the request wrapper.The addition of AuthorizationHeaderRequestWrapper import supports the new security enhancement to control Authorization header propagation.
77-80: Security enhancement: Controlled Authorization header propagation.Wrapping the request with AuthorizationHeaderRequestWrapper and passing an empty authorization header prevents downstream components from accessing the raw Authorization header after JWT validation, which is a good security practice.
82-90: Improved conditional structure for JWT validation.The restructured conditional logic with improved if-else if-else structure makes the code more readable and maintainable, clearly separating the different authentication scenarios.
91-101: Added support for mobile client authentication.This new code branch properly handles mobile clients by:
- Checking User-Agent header to identify mobile clients
- Setting the User-Agent in ThreadLocal context for downstream components
- Properly clearing the ThreadLocal in a finally block to prevent memory leaks
The try-finally block ensures proper resource cleanup even if an exception occurs during filter chain processing, which is a best practice.
src/main/java/com/iemr/mmu/service/registrar/RegistrarServiceImpl.java (5)
72-72: Good addition of the required import.The import of
RestTemplateUtilis necessary for the refactoring of HTTP request entity creation in multiple methods.
703-703: Centralizing HTTP request entity creation improves code maintainability.The refactoring removes duplicate code for manual header construction and standardizes the HTTP request entity creation process.
731-731: Consistent application of the refactoring pattern.The use of
RestTemplateUtil.createRequestEntityhere maintains consistency with other REST API calls.
751-751: Streamlined HTTP entity creation.The standardized approach for creating request entities simplifies the code and reduces potential for errors.
774-774: Consistent implementation of the utility method.This change completes the refactoring pattern across all REST API calls in the class.
src/main/java/com/iemr/mmu/utils/http/AuthorizationHeaderRequestWrapper.java (1)
1-42: Well-implemented request wrapper for Authorization header handling.The class follows the standard wrapper pattern for HTTP servlet requests and correctly overrides the necessary methods to handle the Authorization header.
src/main/java/com/iemr/mmu/utils/RestTemplateUtil.java (1)
13-42: Good centralization of HTTP request entity creation logic.The utility class effectively centralizes the creation of HTTP entities with appropriate headers, improving code maintainability and consistency across the application.

🛠️ Refactor suggestion
Add null check for authorization parameter.
The constructor should validate that the authorization parameter is not null to prevent NullPointerExceptions.
public AuthorizationHeaderRequestWrapper(HttpServletRequest request, String authHeaderValue) {
super(request);
+ if (authHeaderValue == null) {
+ throw new IllegalArgumentException("Authorization header value cannot be null");
+ }
this.Authorization = authHeaderValue;
}🤖 Prompt for AI Agents
In src/main/java/com/iemr/mmu/utils/http/AuthorizationHeaderRequestWrapper.java
around lines 13 to 16, the constructor assigns the authorization parameter
without checking for null, which can cause NullPointerExceptions. Add a null
check for the authHeaderValue parameter at the start of the constructor and
throw an IllegalArgumentException or handle the null case appropriately to
ensure the parameter is not null before assignment.

Add null checks for header values.
The code doesn't handle cases where header values might be null, potentially leading to NullPointerException or unexpected behavior.

add null checks before adding header values to avoid NullPointerException.
Specifically, check if requestHeader.getHeader("JwtToken") and
jwtTokenFromCookie are not null before adding them to headers. If they are null,
either skip adding those headers or handle the null case appropriately to
prevent unexpected behavior.

🛠️ Refactor suggestion
Improve exception handling for JWT token extraction.
The current implementation catches exceptions but only prints the stack trace without proper logging or fallback mechanism.
try {
jwtTokenFromCookie = CookieUtil.getJwtTokenFromCookie(requestHeader);
} catch (Exception e) {
- e.printStackTrace();
+ // Use logger instead of printStackTrace
+ logger.error("Error extracting JWT token from cookie", e);
+ // Consider setting a default value or taking appropriate action

In src/main/java/com/iemr/mmu/utils/RestTemplateUtil.java around lines 25 to 30,
the exception handling for extracting the JWT token from the cookie only prints
the stack trace, which is insufficient. Replace the printStackTrace call with
proper logging of the exception using a logger, and implement a fallback
mechanism such as returning a default value or rethrowing a custom exception to
handle the failure gracefully.
