# Technical Standards ## 1. Folder Strategy (Box) - `/input`: Source files. - `/success`: Original file after COMPLETED status. - `/error`: Original file + Error CSV after FAILED status or if partial errors exist. ## 2. Implementation Standards - **Reader**: Must support `.csv`, `.xls`, `.xlsx`. - **Processor**: 100% logic here. Return a Wrapper object containing [OriginalData, ValidatedEntity, ErrorMessage]. - **Writer**: - Valid records -> MyBatis -> Stored Procedure. - Invalid records -> FlatFileItemWriter -> `[filename]_error_[timestamp].csv`. - **MyBatis**: Use `BATCH` executor and `CALLABLE` statement type.
