21-22: Add cross-field validation for password confirmation.While the individual field validations are good, there's no validation to ensure
confirmPasswordmatchespassword. Consider adding a custom validation annotation or implementing the validation logic inToBeValidated.Here's a suggested approach using a custom annotation:
@PasswordMatch(message = "{validation.password.mismatch}") public class SignupDTO extends ToBeValidated { // existing fields... } @Constraint(validatedBy = PasswordMatchValidator.class) @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @interface PasswordMatch { String message() default "Passwords don't match"; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; }

14-16: Enhance field safety and consider thread synchronizationSeveral improvements could be made to the field declarations:
- The
errorMapshould be made final to prevent null assignment- Consider making it thread-safe if used in concurrent contexts
- The
errorMsgfield seems redundant witherrorMapprivate boolean validated = false; - private Map<String, String> errorMap = new HashMap<>(); + private final Map<String, String> errorMap = new HashMap<>(); - private String errorMsg;
12-12: Add documentation and consider validation lifecycle hooksThe abstract class would benefit from:
- Clear Javadoc explaining its purpose, usage, and contract for subclasses
- Protected lifecycle hooks for subclasses to customize validation behavior
+/** + * Abstract base class for objects that require validation. + * Subclasses should implement their specific validation logic + * and use the error handling methods provided by this class. + */ public abstract class ToBeValidated { + + /** + * Called before validation starts. + * Subclasses can override to perform initialization. + */ + protected void beforeValidation() {} + + /** + * Called after validation completes. + * Subclasses can override to perform cleanup. + */ + protected void afterValidation() {}sep490-idp/src/main/java/sep490/idp/service/impl/UserServiceImpl.java (4)
42-43: Consider adding debug logging for validation failuresAdding debug logging would help with troubleshooting validation issues in production.
validator.validate(signupDTO); + if (log.isDebugEnabled() && !signupDTO.isValidated()) { + log.debug("Validation failed for signup DTO: {}", signupDTO.getFirstErrorMsg().orElse("No message")); + } if (!signupDTO.isValidated()) {
45-45: Avoid potential null error messagesThe
getFirstErrorMsg().orElse(null)could lead to null error messages being set. Consider providing a default error message instead.- result.setErrorMessage(signupDTO.getFirstErrorMsg().orElse(null)); + result.setErrorMessage(signupDTO.getFirstErrorMsg().orElse("Validation failed. Please check your input."));
42-47: Consider restructuring the success flag initializationThe success flag is initially set to true and then potentially set to false after validation. Consider initializing it based on the validation result to avoid the potential for inconsistent states.
SignupResult result = new SignupResult(); result.setRedirectUrl("redirect:/login"); - result.setSuccess(true); validator.validate(signupDTO); - if (!signupDTO.isValidated()) { - result.setSuccess(false); - result.setErrorMessage(signupDTO.getFirstErrorMsg().orElse(null)); - result.setRedirectUrl("signup"); - } + boolean isValid = signupDTO.isValidated(); + result.setSuccess(isValid); + if (!isValid) { + result.setErrorMessage(signupDTO.getFirstErrorMsg().orElse("Validation failed. Please check your input.")); + result.setRedirectUrl("signup"); + }
42-47: Consider extracting URL management to constantsThe redirect URLs are hardcoded strings. Consider extracting them to constants for better maintainability.
+ private static final String LOGIN_REDIRECT_URL = "redirect:/login"; + private static final String SIGNUP_URL = "signup"; private SignupResult validateSignupDTO(SignupDTO signupDTO) { SignupResult result = new SignupResult(); - result.setRedirectUrl("redirect:/login"); + result.setRedirectUrl(LOGIN_REDIRECT_URL); result.setSuccess(true); validator.validate(signupDTO); if (!signupDTO.isValidated()) { result.setSuccess(false); result.setErrorMessage(signupDTO.getFirstErrorMsg().orElse(null)); - result.setRedirectUrl("signup"); + result.setRedirectUrl(SIGNUP_URL); }sep490-idp/src/main/java/sep490/idp/validation/Validator.java (1)
8-12: Enhance method documentation for validation behavior.The current documentation could be more specific about:
- The validation process and error handling
- The state changes in the validated object
- Expected behavior when validation fails
Consider updating the javadoc:
/** - * Validate the whole object and set value to flag and map + * Validates the object and updates its internal validation state. * * @param toValidate the object to be validated + * @throws IllegalArgumentException if the object is null + * @see ToBeValidated for the contract on storing validation errors */

7-7: LGTM! Import changes align with the new validation architecture.The import change correctly reflects the transition from the
ToValidatedinterface to the newToBeValidatedabstract class.
13-13: Verify consistent adoption of ToBeValidated across DTOs.The inheritance change from
ToValidatedinterface toToBeValidatedabstract class looks good and aligns with the new validation architecture.Let's verify that this architectural change has been consistently applied across other DTOs:
✅ Verification successful
Inheritance pattern is correctly implemented
The current inheritance structure is appropriate:
- SignupDTO correctly extends ToBeValidated for complex validation
- Other DTOs are either records, simple validation cases, or base types that don't require ToBeValidated functionality
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Check for any remaining usages of the old ToValidated interface # and verify consistent adoption of ToBeValidated # Check for any remaining implementations of ToValidated echo "Checking for remaining ToValidated implementations..." rg "implements.*ToValidated" -g "*.java" # Check for adoptions of ToBeValidated echo "Checking ToBeValidated usage..." rg "extends.*ToBeValidated" -g "*.java" # Look for potential DTOs that might have been missed echo "Checking for potential DTOs that might need updating..." fd -e java -x grep -l "DTO" {} \; | xargs rg -L "ToBeValidated"Length of output: 883

4-4: Verify all implementations are updated for the breaking change.The change from
ToValidatedtoToBeValidatedis a breaking change that affects the entire validation hierarchy.Run this script to verify all implementations are updated:
✅ Verification successful
Breaking change has been properly implemented
All implementations have been updated to use the new
ToBeValidatedbase class. The validation chain is complete and consistent:
SignupDTOextendsToBeValidatedSignupValidatorimplementsValidator<SignupDTO>- No traces of the old
ToValidatedremain in the codebase🏁 Scripts executed
The following scripts were executed for the analysis:

21-26: Well-structured validation approach!Good implementation that collects all validation errors instead of stopping at the first one, providing better user experience by showing all issues simultaneously.
20-28: Verify password security requirementsThe current validation only checks if passwords match. Consider adding additional security validations such as minimum length, complexity requirements, and common password checks.
Let's check if there are any password security requirements defined elsewhere:

20-28: 🛠️ Refactor suggestionFix incorrect error key mapping for email validation
The email existence error is still being added to the "password" key instead of the "email" key.
Consider adding essential signup validations
The current validation is limited to password matching and email existence. Consider adding these essential validations:
- Email format validation
- Password complexity requirements (length, special characters, etc.)
- Username requirements (if applicable)
Example implementation for additional validations:
public void validate(SignupDTO dto) { + // Email format validation + if (!isValidEmailFormat(dto.getEmail())) { + dto.addError("email", "validation.email.invalid.format"); + } + // Password complexity + if (!meetsPasswordComplexity(dto.getPassword())) { + dto.addError("password", "validation.password.invalid.complexity"); + } if (!passwordsMatch(dto)) { dto.addError("password", "validation.password.invalid.notmatch"); } if (userRepo.existsByEmail(dto.getEmail())) { - dto.addError("password", "validation.email.invalid.exist"); + dto.addError("email", "validation.email.invalid.exist"); } checkValidated(dto); }

13-15: Consider improving testabilityThe validation logic in private helper methods makes it difficult to unit test individual validation rules. Consider:
- Extracting validation rules into separate, testable components
- Making helper methods protected for better testability
Example refactor:
@Component @Qualifier("signupValidator") @RequiredArgsConstructor -public class SignupValidator implements Validator<SignupDTO> { +public class SignupValidator implements Validator<SignupDTO> { + protected interface ValidationRule { + boolean validate(SignupDTO dto); + String getErrorKey(); + String getErrorMessage(); + }

30-33: Ensure complete validation state handlingThe method only sets
validatedto false when errors exist, but doesn't handle the success case. This could leave the validation state undefined when there are no errors.
