参考 ruoyi-oracle，添加序列
    #if($pkColumn.increment)
    -- ${tableName}主键序列
    create sequence seq_${tableName}
    increment by 1
    start with 10
    nomaxvalue
    nominvalue
    cache 20;
    #end

GenTable
    /** 菜单id **/
    private Long menuId;
    
GenTableServiceImpl
    generatorCode()
    // 获取菜单id序列，用于生成菜单sql语句
    long menuId = genTableMapper.selectMenuId();
    table.setMenuId(menuId);
    
参考 RuoYi-Oracle，修改为 Oracle 可用的格式，调整路径相关
