AI Technical Summary
Technical Problem
In ORM frameworks, developers need to manually generate a large number of repetitive DAO and Mapper files, which leads to a large workload, a high risk of errors, high maintenance complexity, and poor flexibility and scalability.
Method used
During the application startup phase, the project code is traversed, database entity objects are identified and metadata is parsed, a general Mapper is configured, generic DAO class instances are generated, and they are registered through the IOC container to simplify the database operation process.
Benefits of technology
Improve development efficiency, reduce manual errors and maintenance costs, simplify database operation processes, and enhance code flexibility and scalability.

Abstract
This invention discloses an automatic ORM DAO code generation method based on database entity objects, belonging to the field of data processing technology. The method includes: traversing the project code during application startup to identify entity objects in the database and parse entity metadata based on preset annotations or class characteristics; configuring a generic Mapper to provide database operation methods shared by all tables; binding entity objects to generic DAO classes based on the generic Mapper to generate DAO instances corresponding to the entity objects; and registering the DAO instances to the IOC container as Bean definitions through the IOC container extension interface, enabling them to be instantiated and injected in subsequent lifecycles for database operations. This invention solves the technical problems of existing ORM frameworks having a large amount of repetitive code and the tedious manual generation of DAO and Mapper files, achieving the technical effects of improving development efficiency, reducing manual errors, and lowering maintenance costs.
