What is the method for reverse engineering in MyBatis?

The reverse generation method of MyBatis involves using the MyBatis Generator tool to read the database table structure information and create corresponding Java code files, including entity classes, Mapper interfaces, and XML mapping files.

The steps to generate code using MyBatis Generator are as follows:

1. Set up database connection information and generation rules: Configure database connection information, generate code paths, and tables in the generatorConfig.xml file.
2. Run the MyBatis Generator tool by running it through the command line or IDE plugin, passing in the path to the generatorConfig.xml file.
3. Java code files are automatically generated by MyBatis Generator based on the configured table information, which reads the database table structure and generates corresponding Java entity classes, Mapper interfaces, and XML mapping files.

The generated Java code files can be directly used for developing the persistence layer, reducing the manual workload of writing repetitive code. Additionally, MyBatis Generator also supports custom plugins and configurations, allowing for extension and customization based on specific needs.
