From 38168d129b6b754eb862dfa6ca348ae757d8a0ef Mon Sep 17 00:00:00 2001 From: Brian Sam-Bodden Date: Fri, 5 Sep 2025 09:50:29 -0700 Subject: [PATCH 1/2] test: add test case demonstrating projection issue with non-String fields - Created test entity with mixed field types (Integer, Double, Boolean, LocalDate) - Added projection interfaces with and without @Value annotations - Test shows that non-String fields require @Value annotation to work properly - The workaround of using @Value annotation works as expected This test documents the behavior described in issue #650 where projection interfaces return null for non-String fields unless @Value annotation is used.

This was due to incomplete handling of field types during projection result processing. This fix addresses the issue in two places: 1. MappingRedisOMConverter: Added projection interface introspection to determine property types for proper conversion when processing hash-based repositories 2. RediSearchQuery: Enhanced parseDocumentResult() to handle both full JSON documents and individual fields returned during projection optimization, with proper type conversion for booleans (stored as 1/0), dates (stored as timestamps), and other non-String types The framework now correctly handles all field types in projection interfaces without requiring the @Value annotation workaround.
