…mentation Complete implementation of Statement and StatementRef entities per customer.xsd specification (lines 285-307, 373-393) following Phase 17/18 patterns. Schema Compliance Changes: - StatementRefEntity: Changed from @entity to @embeddable (extends Object, not IdentifiedObject) - Removed UUID primary key, now stored as @ElementCollection in StatementEntity - statement_refs table: Removed id column, now collection table with statement_id FK only - StatementDto: Removed ALL IdentifiedObject fields, keeps ONLY issueDateTime + statementRef per XSD - StatementRefDto: Fixed to match XSD (fileName, mediaType, statementURL only) Entity Enhancements: - Added @manytoone relationships for Controller API navigation: * customer_id → CustomerEntity * customer_account_id → CustomerAccountEntity * customer_agreement_id → CustomerAgreementEntity * usage_summary_id → UsageSummaryEntity - Updated toString() to follow database field sequence per CLAUDE.md guidelines - @AssociationOverride for statement_related_links (bidirectional Atom protocol links) Database Migration (V3): - statements table: Added customer_account_id, customer_agreement_id, usage_summary_id FKs - Removed non-schema fields: statement_date, billing_period_start, billing_period_duration - statement_refs table: Restructured as @ElementCollection table (no id column) - Added indexes for all relationship foreign keys Mapper Implementation: - StatementMapper: Maps ONLY customer.xsd fields (issueDateTime, statementRef) - StatementRefMapper: Direct 1:1 field mapping (3 fields) - Uses qualifiedByName for DateTimeMapper epoch conversions - Follows DRY principle - Atom metadata handled by AtomEntryDto/LinkDto Repository & Service Simplification: - Removed 7 non-ID query methods from StatementRepository - Added 4 ID-based relationship queries (Customer, CustomerAccount, CustomerAgreement, UsageSummary) - Removed 10 methods from StatementService (date/description/count queries) - Kept only CRUD + ID-based operations per ESPI compliance patterns Resolves #28 Phase 19 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Test Coverage: - StatementRepositoryTest: 7 tests for CRUD + ID-based relationship queries - StatementPostgreSQLIntegrationTest: 4 tests with real PostgreSQL TestContainer - StatementMySQLIntegrationTest: 4 tests with real MySQL TestContainer Key Test Scenarios: - @ElementCollection StatementRef persistence (no id column) - All 4 relationship queries (Customer, CustomerAccount, CustomerAgreement, UsageSummary) - Cascading delete of @ElementCollection - CRUD operations with real databases Results: 781 total tests passing (added 15 new tests) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
…lity Issue: CI/CD failing due to timestamp precision mismatch between platforms - Windows: microseconds (6 decimals) - Linux/Mac: nanoseconds (9 decimals) Solution: Truncate all test timestamps to MICROS using .truncatedTo(ChronoUnit.MICROS) Changes: - StatementRepositoryTest: 3 occurrences fixed - StatementMySQLIntegrationTest: 3 occurrences fixed - StatementPostgreSQLIntegrationTest: 3 occurrences fixed Results: All 781 tests passing locally Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
