Code Generator Implementation

Create a main method with the following configuration:

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.Collections;

public class CodeGenerator {
    private static final String DB_URL = "jdbc:mysql://localhost:3306/your_database?useSSL=true&useUnicode=true&characterEncoding=UTF8&serverTimezone=Asia/Shanghai";
    
    public static void main(String[] args) {
        FastAutoGenerator.create(DB_URL, "your_username", "your_password")
            .globalConfig(builder -> {
                builder.author("developer_name")
                       .enableSwagger()
                       .fileOverride()
                       .outputDir("/path/to/output/directory");
            })
            .packageConfig(builder -> {
                builder.parent("com.yourcompany")
                       .moduleName("yourmodule")
                       .pathInfo(Collections.singletonMap(OutputFile.xml, "/path/to/xml/output"));
            })
            .strategyConfig(builder -> {
                builder.addInclude("table_name")
                       .addTablePrefix("prefix_");
            })
            .templateEngine(new FreemarkerTemplateEngine())
            .execute();
    }
}

Note: Ensure the output directory paths are correctly specified for your project structure.

Configuration Options

Additional configuration options are available through the various buillder methods for database connection, pacckage structure, table strategies, and template engines.
