引用不了XXservice,怎么办？

1、
tEdasArchiveLogService = (TEdasArchiveLogService) SpringContextHolder.getBean("TEdasArchiveLogService");

2、
ServletContext sc = request.getSession().getServletContext();
//获取spring容器
ApplicationContext app=WebApplicationContextUtils.getRequiredWebApplicationContext(sc);
TEdasFilesService tEdasFilesService=app.getBean(TEdasFilesService.class);
