Description copied from interface: ConnectionCustomizer

Called immediately after a Connection is acquired from the underlying database for incorporation into the pool.

This method is only called once per Connection. If standard JDBC Connection properties are modified — specifically catalog, holdability, transactionIsolation, readOnly, and typeMap — those modifications will override defaults throughout the Connection's tenure in the pool.
