Research direction
Investigate the custom converter registration mechanism in easyexcel. Compare the annotation based approach and global configuration. Check the issue's provided code snippets and the relevant source files such as ExcelReaderBuilder or annotation processors. Look for any recent changes that might have broken the annotation based converter specification. Consider Spring Boot auto configuration interactions.
