Method and system for dynamically creating data tables

Abstract

The invention discloses a method for dynamically creating data tables based on Hibernate platform. The method comprises: A, determining the structure of a data table and generating an XML description document containing the structure information of the data table; and B, creating the physical table structure of the data table according to the XML description document, generating a data-table mapping file and mapping-class files according to the XML description document and a corresponding conversion template, and compiling the mapping-class files to get java class files of the mapping-class files. The invention also discloses a system for dynamically creating data tables based on Hibernate platform. The method and the system can dynamically create and access Hibernate platform data tables.

Description

technical field [0001] The invention relates to the application field of the Hibernate platform, in particular to a method and a system for dynamically creating data tables based on the Hibernate platform. Background technique [0002] At present, in the field of enterprise application development using Java EE, a large number of people have adopted the Hibernate platform as a tool for enterprise applications to access enterprise data. [0003] Hibernate is an object-relational mapping (ORM) technology platform. The so-called ORM is to map the relational model (Relation) of the database into an object model (Object). By applying this technology, in the development process of enterprise applications, The user directly calls the object to perform object-oriented operations, but finally can realize the data access of the database. Because the Hibernate platform encapsulates the database access, it greatly simplifies the process of users accessing the database. Therefore, the H...

[0004] However, in the process of users using the Hibernate platform, there is a common problem, that is, the access to each data table requires the creation of corresponding data tables, the creation of mapping files, and the creation of mapping classes during the development process. Create a series of work, so that the access to an existing data table under the Hibernate platform can be realized

However, actual enterprise applications often have business requirements that need to dynamically create data tables during system operation, and for such business requirements, the Hibernate platform cannot meet the data access to dynamic data tables, so that current enterprise applications are dealing with such Most of the problems are bypassing the Hibernate platform, and this will undoubtedly make the Hibernate platform less attractive in the process of using it.
