/**
* 服务员工作线程
*
* @author duanyy
* @version 1.0.2 [20140407 duanyy]
* - 采用{@link java.util.concurrent.CountDownLatch CountDownLatch}来和主进程通讯.
*
* @version 1.4.0 [20141117 duanyy]
* - Servant体系抛弃MessageDoc
*
* @version 1.6.5.6 [20160523 duanyy]
* - 淘汰MessageDoc，采用Context替代
*
* @version 1.6.5.6 [20160523 duanyy]
* - bizlog增加报文长度
* - 在action中提前写出报文
* - 增加trace日志
*
* @version 1.6.5.7 [20160525 duanyy]
* - trace可选择关闭
