What is reverse engineering in MyBatis?

Reverse engineering in MyBatis is an automated tool used to generate corresponding Java entity classes, Mapper interfaces, and Mapper.xml files based on the database table structure. With the help of reverse engineering tools, developers do not need to manually write entity classes and Mapper files corresponding to database tables, which can save a significant amount of time and effort.

Reverse engineering tools can automatically generate entity class properties and methods, as well as SQL statements in Mapper interfaces, by reading the metadata information of the database. Developers can customize the tool as needed, such as specifying the package name for generated entity classes, Mapper interface, and SQL statements. This greatly improves development efficiency and ensures that the generated code remains consistent with the database table structure, reducing the risk of errors.
