To set up MyBatis Generator for automatic code generation, the following steps need to be taken:

Add the MyBatis Generator plugin dependency: include the MyBatis Generator plugin dependency in the `pom.xml` file of your project. For example:


  
    
    
      org.mybatis.generator
      mybatis-generator-maven-plugin
      1.4.0
      
        
        
          mysql
          mysql-connector-java
          8.0.23
        
        
      
      
        
          Generate MyBatis Artifacts
          generate-sources
          
            generate

Please ensure that you set the values of “`, “`and“`correctly, and choose the appropriate driver dependency based on the database you are using.

Configure the MyBatis Generator generation rules: The generation rules of MyBatis Generator can be configured in the plugin’s `` tag.

For example:

Set up the database connection information:


  com.mysql.cj.jdbc.Driver
  jdbc:mysql://localhost:3306/mydatabase
  root
  password

Modify the “, “, “, and “ according to your database type and connection information.

Generate entity class configuration.

Set “table name” as the name of the table that needs to be generated into an entity class, and set “entity class name” as the name of the generated entity class. If there is an auto-increment primary key.

In the column, you can use “Configure to generate primary key strategy”.

Generating Mapper interfaces and XML files configuration:

Set “

” as the table name for which you need to generate Mapper interface and XML file, and “” as the corresponding entity class name.

Set “generated Mapper interface name” as.

3. Run the generate command: Open the terminal or command prompt in the project’s root directory and execute the following command to start the code generator.

mvn mybatis-generator:generate

After successful execution, MyBatis Generator will generate corresponding code files according to the configuration.
