******* spring getBean 的问题 ********

**** spring + hibernate 的工程
ServletContext servletContext = request.getSession().getServletContext();
WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
SubTaskServiceImpl subTaskService = (SubTaskServiceImpl)wac.getBean("subTaskServiceImpl");
这样拿到的subTaskService来操作dao会导致事物不起作用，或连接池的连接不释放吗？和setter注入再拿来用有什么区别？

In spring,a spring springs into spring spring是什么意思 pierian spring Spring came. spring 问题 spring line Spring Festival in spring in spring 还是in the spring Happy spring festival
