web调用后台程序spring无法注入问题

架构是这样的 ssh(struts2,spring3.1,hibernate4) action->el->service-dao
el模块里有个 线程池 ,我管 线程池 叫 工头 .然后el模块还有个线程类.我管这个 线程类 叫 工人 .
工头从任务队列添加任务,工头要先查下数据库这个任务是否(调service查找),这个时候service对象是为空的,
我分析了是service里的dao里的sessionFactiory,是为空,导致层层都没有获取成功,我现在假设把线程池对象交给spring管理那么线程池产生的线程对象也是交给spring,可能这种做法不是很好,但是不交给spring的话,service老为空,注意:工头也调service,工人也是调service .
如果可以解决service不为空, 解决这个问题也可以不交spring管理
也分享一下我感觉比较爽的配置文件
