Release Notes - Version 2.3.2

Overview

Version 2.3.2 is a maintenance release that addresses critical bugs in WebClient Buffer Limit Exception for Large Files.

Bug Fixes

1. WebClient Buffer Limit Exception for Large Files

• Problem: DataBufferLimitException thrown when response body exceeds 256KB (default WebClient buffer limit).
• Impact: Affected APIs returning large files (e.g., text-to-audio returning 472KB audio files).
• Solution: Implemented streaming response handling to avoid buffer limits:
  • Changed from retrieve().toEntity(byte[].class) to exchangeToMono() with streaming
  • Used bodyToFlux(DataBuffer.class) to read data in chunks
  • Immediate DataBuffer release to prevent memory buildup
  • Merged chunks using reduce operation
• Benefits:
  • Handles responses of any size without configuration changes
  • Consistent with Spring Boot 3 RestClient behavior
  • Improved exception handling and logging (debug → error level)
• Affected components:
  • WebClientExecutor.executeForEntity() methods (both Class and TypeReference variants)
  • WebClientExecutorTest - Updated test mocks to use exchangeToMono()
