/**
 * A data access object (DAO) providing persistence and search support for
 * TestpaperTable entities. Transaction control of the save(), update() and
 * delete() operations can directly support Spring container-managed
 * transactions or they can be augmented to handle user-managed Spring
 * transactions. Each of these methods provides additional information for how
 * to configure it for the desired type of transaction control.
