Summary

Phase 5 of the ESPI 4.0 schema compliance project updates IntervalBlock entity, DTO, mapper, repository, and tests to match the espi.xsd element sequence and optimize for read-only operations.

Changes Made

IntervalBlockDto

• ✅ Updated field order to match espi.xsd IntervalBlock element sequence
• ✅ Removed Atom-level fields (published, updated, relatedLinks, selfLink, upLink, description)
• ✅ Kept only ESPI schema fields: interval, intervalReadings
• ✅ Updated all constructors to match new field order
• ✅ Removed unused OffsetDateTime import
• ✅ Added ESPI 4.0 schema compliance documentation

IntervalBlockMapper

• ✅ Updated toDto mapping - removed mappings for deleted Atom fields
• ✅ Updated toEntity mapping - marked Atom fields as ignore=true
• ✅ Removed updateEntity method (read-only operations only)
• ✅ Removed unused @MappingTarget import

IntervalBlockRepository

• ✅ Optimized to keep only indexed queries:
  • findAllIds() - returns all interval block IDs
  • findAllByMeterReadingId() - indexed on meter_reading_id
  • findAllIdsByUsagePointId() - indexed through relationships
• ✅ Removed non-indexed queries:
  • deleteByUuid() - redundant with inherited deleteById()
  • findAllIdsByXpath3() - complex join without index
  • findIdByXpath() - complex join without index
  • findByMeterReadingEntity() - duplicate of findAllByMeterReadingId()
  • findByUri() - non-indexed query on self_link_href

IntervalBlockServiceImpl

• ✅ Updated findAllByMeterReading() to use findAllByMeterReadingId()
• ✅ Deprecated findByURI() with warning (non-indexed query removed)

IntervalBlockRepositoryTest

• ✅ Removed redundant shouldDeleteIntervalBlockByUuid test
• ✅ Removed tests for deleted repository methods:
  • shouldFindAllIntervalBlockIdsByXpath3
  • shouldFindIntervalBlockIdByXpath
  • shouldFindIntervalBlocksByMeterReadingEntity
  • shouldFindIntervalBlockByUri
• ✅ Updated shouldHandleEmptyResultsGracefully test
• ✅ All 24 IntervalBlock tests passing

Validation

• ✅ All 545 openespi-common tests passing
• ✅ IntervalBlockRepositoryTest: 24/24 tests passing
• ✅ DtoExportServiceImplTest validates XML output matches espi.xsd
• ✅ Flyway migration scripts verified (MySQL, PostgreSQL, H2)

XML Output Validation

The DtoExportServiceImplTest confirms proper XML structure:

<espi:IntervalBlock>
  <interval>
    <start>1330578000</start>
    <duration>86400</duration>
  </interval>
  <IntervalReading>
    <cost>974</cost>
    <ReadingQuality>...</ReadingQuality>
    <timePeriod>...</timePeriod>
    <value>282</value>
  </IntervalReading>
  ...
</espi:IntervalBlock>
