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 primarily introduces a new 'Find Login ID' feature, enabling users to retrieve their forgotten login IDs by providing their name and phone number. In addition to this core functionality, I've included important bug fixes for string comparisons in user-related services and refactored API parameter handling for improved clarity and maintainability.
Highlights
- New Feature: Find Login ID: I've implemented a new API endpoint and the corresponding service logic to allow users to find their login ID. This functionality leverages a new repository method to query users by name and phone number, and introduces dedicated request/response DTOs for clarity.
- User DTO Refactoring: The DTOs previously named
FindIdRequestandFindIdResponsehave been removed and replaced withFindLoginIdRequestandFindLoginIdResponse. This renaming provides more precise semantics for the new 'find login ID' feature. - Bug Fix: String Comparison: I've addressed a potential bug in the
findPasswordservice method by updating string comparisons from the==operator to the.equals()method fornameandloginIdfields. This ensures correct content-based string equality checks. - API Parameter Handling Refinement: The
getCustomerKeyendpoint inUserControllerand its associated documentation have been refactored to utilize a custom@UserIdannotation for extracting the user ID. This change streamlines parameter handling and improves consistency across user-specific API calls.

Code Review
This pull request implements the "Find ID" feature with a new endpoint, service logic, and repository method. It also includes a bug fix for string comparison.
My review suggests improvements in a few areas:
- A
highseverity issue regarding a potentialNullPointerExceptionwhen comparing enums. - A
mediumseverity suggestion to refactor a method for conciseness using a functional style. - A
mediumseverity comment regarding a minor scope creep to encourage focused pull requests.

Using .equals() to compare enums can introduce a NullPointerException if payment.getPaymentStatus() is null. Using == is null-safe and the idiomatic way to compare enums in Java.

This implementation can be more concise using the Optional API, avoiding the intermediate user variable and clarifying the data flow.
return userJpaRepository.findByNameAndPhoneNumber(request.name(),
request.phoneNumber())
.map(UserJpaEntity::getLoginId)
.map(FindLoginIdResponse::from)
.orElseThrow(() -> new CustomRuntimeException(ErrorCode.NOT_FOUND_LOGIN_ID));| @GetMapping("/customer-key") | ||

The change from @RequestParam to @UserId is a good refactoring, but it's out of scope for the "Find ID" feature. Submit refactorings in a separate PR for easier reviews and a cleaner commit history. This also applies to UserControllerDocs.java.
