How to quickly generate code with MyBatis?

MyBatis offers a plugin called MyBatis Generator (MBG) for quickly generating code. The following are the steps to generate code using MBG.

1. Add the dependency for the MyBatis Generator (MBG) plugin in the pom.xml file.

<build>
    <plugins>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.4.0</version>
        </plugin>
    </plugins>
</build>

1. Create a configuration file, such as generatorConfig.xml, and place it in the project’s root directory. The file should include details such as database connection information, the type and location of the code to be generated, etc.
2. Add the configuration for the MyBatis Generator (MBG) plugin in the pom.xml file, specifying the configuration file to be used.

<build>
    <plugins>
        <plugin>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-maven-plugin</artifactId>
            <version>1.4.0</version>
            <configuration>
                <configurationFile>generatorConfig.xml</configurationFile>
                <overwrite>true</overwrite>
                <verbose>true</verbose>
            </configuration>
        </plugin>
    </plugins>
</build>

1. Run the following Maven command to generate code:

mvn mybatis-generator:generate

1. MBG will generate corresponding code according to the settings in the configuration file, including entity classes, Mapper interfaces, and XML files.

Before using MBG to generate code, it is necessary to first create the database tables and their corresponding mappings.
