Summary

Complete implementation of Statement and StatementRef entities per customer.xsd specification (lines 285-307, 373-393) following Phase 17/18 established patterns.

Schema Compliance Changes

StatementRef (@embeddable)

  • Changed from @Entity to @Embeddable (extends Object, not IdentifiedObject per XSD)
  • Removed UUID primary key - no longer a separate entity
  • Stored as @ElementCollection in StatementEntity
  • Database: statement_refs collection table with statement_id FK only (no id column)

StatementDto

  • Removed ALL IdentifiedObject fields (id, description, published, updated, links)
  • Keeps ONLY schema fields: issueDateTime, statementRef collection
  • Follows DRY principle - Atom metadata handled by AtomEntryDto/LinkDto wrappers

StatementRefDto

  • Fixed to match customer.xsd lines 285-307
  • Fields: fileName, mediaType, statementURL (3 fields only)

Entity Enhancements

Relationship Support (Controller API Navigation)

Added @ManyToOne relationships with foreign keys:

  • customer_id → CustomerEntity
  • customer_account_id → CustomerAccountEntity
  • customer_agreement_id → CustomerAgreementEntity
  • usage_summary_id → UsageSummaryEntity

Other Improvements

  • Updated toString() to follow database field sequence per CLAUDE.md
  • @AssociationOverride for statement_related_links (bidirectional Atom protocol)

Database Migration (V3)

statements Table

  • Added relationship foreign keys: customer_account_id, customer_agreement_id, usage_summary_id
  • Removed non-schema fields: statement_date, billing_period_start, billing_period_duration
  • Added indexes for all relationship foreign keys

statement_refs Table

  • Restructured as @ElementCollection table (no id column)
  • Fields: statement_id (FK), file_name, media_type, statement_url
  • Single index: idx_statement_ref_statement_id

Mapper Implementation

StatementMapper

  • Maps ONLY customer.xsd fields: issueDateTime, statementRef collection
  • Uses qualifiedByName = "offsetToLong"/"longToOffset" for DateTimeMapper conversions
  • No explicit IdentifiedObject ignores (DRY principle)

StatementRefMapper

  • Direct 1:1 field mapping (3 fields)
  • No transformations needed

Repository & Service Simplification

StatementRepository

  • Removed: 7 non-ID query methods (date/description/reference queries)
  • Added: 4 ID-based relationship queries
    • findByCustomerId(UUID)
    • findByCustomerAccountId(UUID)
    • findByCustomerAgreementId(UUID)
    • findByUsageSummaryId(UUID)

StatementService

  • Removed: 10 non-CRUD methods
  • Kept: CRUD operations + ID-based relationship queries only

Test Coverage

Unit Tests (7 tests)

  • StatementRepositoryTest: CRUD + all ID-based relationship queries
  • Tests @ElementCollection StatementRef persistence

Integration Tests (8 tests)

  • StatementPostgreSQLIntegrationTest: 4 tests with real PostgreSQL TestContainer
  • StatementMySQLIntegrationTest: 4 tests with real MySQL TestContainer
  • Tests cascading delete, relationship queries, collection table persistence

Results

  • Total: 781 tests passing (added 15 new tests)
  • Coverage: Repository, Entity, Integration (MySQL/PostgreSQL)
  • All CI/CD checks pass ✅

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

test: Add comprehensive test suite for Phase 19 Statement implementation
9f0edb3 
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)

…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
