* 游戏区服动态数据库连接工具

*
|

|
|
* 游戏每个区服对应独立的数据库 mir_actor_s{serverId}
|
|||
|
|
* 该模块根据 serverId 动态创建连接池（带缓存，同一区服复用连接）
|
|||
|
|
*
|
|||
|
|
* 使用示例：
|
|||
|
|
* import getGameDB from '../mysql/gameDB.js'
|
|||
|
|
* const db = getGameDB(1)
|
|||
|
|
* const [rows] = await db.query('SELECT ...')
|
|||
|
|

|||
|
|
import * as log4js from '../log4js.js'
|
|||
|
