# MySQL Configuration
db.url=jdbc:mysql://localhost:3306/mydatabase?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
db.username=root
db.password=your_password

public class AppConfig extends JFinalConfig {
    @Override
    public void configPlugin(Plugins plugins) {
        // 配置MySQL数据库插件
        DruidPlugin druidPlugin = new DruidPlugin(getProperty("db.url"), getProperty("db.username"), getProperty("db.password"));
        plugins.add(druidPlugin);

        // 配置ActiveRecord插件
        ActiveRecordPlugin activeRecordPlugin = new ActiveRecordPlugin(druidPlugin);
        plugins.add(activeRecordPlugin);
        
        // 添加映射关系，示例：
        // activeRecordPlugin.addMapping("tableName", YourModel.class);
    }

    // 其他配置和路由配置等...
}

public class User extends Model<User> {
    public static final User dao = new User();

    // 定义表名和主键名
    public static final String TABLE = "user";
    public static final String PRIMARY_KEY = "id";

    // 其他字段定义

    // 示例：查询所有用户
    public List<User> findAllUsers() {
        return dao.find("SELECT * FROM " + TABLE);
    }
}
