数据持久层基于Hibernate框架实现。持久层通过Hibernate

The data persistence layer is based on the Hibernate framework. The persistence layer connects to the database through Hibernate. The business logic layer passes the results of business logic processing to the data persistence layer. The persistence layer uses the Hibernate method to persist the data and write it to the database. Or when the logical layer requests data, the data persistence layer reads the object data from the database and feeds it back to the logical layer. The system's support for data persistence is based on the Hibernate framework. The Hibernate framework reads the configuration file, requests data from the database, and processes the data through the packaged Hibernate method to generate a persistent object (Persistent Object), which will be generated Persistent objects are fed back to the calling logical interface. The persistence layer defines the mapping from data to persistent objects. Hibernate will manage the mapping.

The data persistence layer is implemented based on the Hibernate framework. The persistence layer connects to the database via Hibernate. The business logic layer passes the results of business logic processing to the data persistence layer, which persists the data through the Hibernate method and writes it to the database. Or when the logical layer requests data, the data persistence layer reads the object data from the database and feeds it back up to the logical layer. The system's support for data persistence is based on the Hibernate framework, which processes the data from the database by reading configuration files, and processes the data through the encapsulated Hibernate method, generates persistent objects ( Persistent Object), and then feeds the generated persistent objects up to the logical interface of the call. The persistence layer defines the mapping from the data to the persistent object. Hibernate manages the mapping.
