Why MyBatis‑Plus Migration Fails: LocalDateTime Conversion and Connector Version Issues

A legacy project using MySQL 5.7, MyBatis 3.5.0 and mysql‑connector‑java 5.1.26 encounters a "Conversion not supported for type java.time.LocalDateTime" error after switching to MyBatis‑Plus 3.1.1, which is traced to MyBatis 3.5.1 dropping built‑in LocalDateTime handling and the old connector not supporting the type, requiring an upgrade to mysql‑connector‑java 5.1.37 or later.
