Problems solved by technology

However, when using mybatis, you need to create a mapping (mapper) file based on the data table fields, and you need to configure the dependencies between them. This kind of work is very trivial and repetitive. Although mybatis officially provides tools to assist in the creation, these tools still need Manually add a large number of configuration parameters, and each time you need to manually execute to generate a new mapper file, this process is still relatively cumbersome

Abstract

The invention discloses a database mapping file generation method and device, equipment and a storage medium, relates to the technical field of databases, and is used for improving the generation efficiency of a database mapping file. The method comprises the steps that in the compiling process of a target Maven project, a mapping file generation plug-in introduced into a project object model file corresponding to the target Maven project is triggered, and a mapping file is generated according to the mapping file generation plug-in; analyzing an entity relation graph file corresponding to a target database to obtain at least one entity element set included in the entity relation graph file; creating an entity class set, and storing the at least one element set in the entity class set; and calling the mapping file generation plug-in, traversing each database table in the entity class set, and generating a corresponding mapping file for each database table.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of database technology, and provides a method, device, equipment and storage medium for generating a database mapping file. Background technique [0002] Java is an object-oriented enterprise-level application development language. When using the Java language for application system development, it is generally inseparable from the operation of the database. The Java language exposes the interface to the database operation, and the specific implementation is determined by the database. implemented by the provider itself. [0003] At present, the more commonly used object relational mapping (Object Relational Mapping, ORM) frameworks of the Java language class data layer include Hibernate and Mybatis. Mybatis is widely used because of its lightweight framework and flexible use. However, when using mybatis, you need to create a mapping (mapper) file based on ...
