Summary of Changes
Hello @polyglot-k, 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!
I've implemented changes to differentiate between guest and general user phone numbers within the system. This involves prefixing phone numbers with 'G' for guests and 'U' for regular users to clearly distinguish their accounts in the database and ensure proper handling across various services.
Highlights
- Phone Number Formatting: I've introduced new utility methods in
PhoneNumberUtilto prefix phone numbers with 'G' for guest users and 'U' for general users, ensuring distinct identification within the system. - User Data Handling: I've updated user creation and update flows in
ApplicationGuestRequest,SignUpAccountRequest, andOAuthUserPersistenceProcessorto apply these new phone number formatting rules consistently. - User Lookup Consistency: I've modified
MyUserServiceto correctly retrieve user information by applying the standard phone number format during lookups, ensuring compatibility with the newly prefixed numbers. - External System Compatibility: I've adjusted
NotifyServiceand added agetPhoneNumber()method inUserJpaEntityto strip the prefix when retrieving phone numbers for external use, ensuring compatibility with existing notification systems and external integrations.

Code Review
This pull request introduces a mechanism to distinguish between guest and regular user phone numbers by adding a 'G' or 'U' prefix. The changes are applied across user creation and update flows. My review focuses on improving the implementation's robustness and maintainability. I've identified a critical issue in UserJpaEntity where a getter is overridden in a way that could lead to a NullPointerException and other subtle bugs. I've also suggested centralizing the logic for removing the phone number prefix into PhoneNumberUtil to avoid code duplication and improve clarity.

| return phoneNumber.replaceFirst("^.", ""); | ||

Overriding a getter for a JPA entity field to return a modified value is an anti-pattern. It can cause unexpected behavior with persistence frameworks and breaks the principle of least astonishment. A getter should return the raw field value. It's recommended to rename this method to something like getRawPhoneNumber() and restore the default getter for phoneNumber (e.g., by letting Lombok generate it).
Additionally, the current implementation phoneNumber.replaceFirst("^.", "") will throw a NullPointerException if phoneNumber is null, as the field is nullable.
Here is a safer implementation with a more appropriate method name:
public String getRawPhoneNumber() {
if (phoneNumber == null || phoneNumber.isEmpty()) {
return phoneNumber;
}
return phoneNumber.substring(1);
}| public static String formatPhoneNumber(String phoneNumber) { | ||
| return String.format("U%s", phoneNumber); | ||
| } |

To avoid duplicating the logic for removing the phone number prefix (as seen in NotifyService and UserJpaEntity), and to improve readability over replaceFirst("^.", ""), consider adding a utility method here to handle that.
This centralizes the logic and makes the code easier to maintain. You can then use PhoneNumberUtil.stripPrefix() in other parts of the code.
public static String formatPhoneNumber(String phoneNumber) {
return String.format("U%s", phoneNumber);
}
public static String stripPrefix(String phoneNumber) {
if (phoneNumber == null || phoneNumber.isEmpty()) {
return phoneNumber;
}
return phoneNumber.substring(1);
}
