A Java EE Data Persistence Layer Model Based on Multi Persistence Technology

Aiming at how to improve the execution efficiency and development efficiency of Java EE application data persistence layer, the popular JDBC, MyBatis framework and Spring Data JPA are selected as the research objects of persistence technology. Their architecture and persistence operation process are analyzed and combined with the DAO design model. A data persistence layer model integrating the three is proposed. The model relies on JDBC interface, mapper interface and repository interface to interact with database in DAO implementation class. At the same time, the selector is used to switch between different persistence technologies according to the record number of database table. The model is applied to the development of data persistence layer in the target assessment system of colleges and universities, JDBC, MyBatis and Spring Data JPA are used as development methods to compare with the model in this paper. Practice shows that this model can ensure that every persistent operation has the best execution efficiency and higher development efficiency.
